''{Scene fades in on Thel 'Vadamee and Rtas 'Vadumee, who is in a Wraith with its hatch open, conversing. The two are looking towards the Control Room of Delta Halo}''

Thel 'Vadamee: "What is that place?"

Rtas 'Vadumee: "Where the Councilors were meant to watch the consecration of the Icon." {Zooms in on Rtas 'Vadumee's face} "The start of the Great Journey."

{Focus on 'Vadamee}

Gravemind {in 'Vadamee's memory }: "There is still time to stop the key from turning."

{'Vadamee turns to face Rtas 'Vadumee}

Thel 'Vadamee: "I must get inside."

Rtas 'Vadumee: "Then mount up, Arbiter. I know a way to break those doors."

{'Vadamee turns to face the Control Room as Rtas 'Vadum enters his Wraith and closes the hatch behind him}

Gameplay
{they travel to where a Scarab is visible, docked up on a ledge}

Rtas 'Vadumee: "There, Arbiter. That Scarab's main gun will break the Control Room's door. At the far end of the beach there's a passage into the cliff. It'll take you up to the Scarab."

{after clearing the area}

Rtas 'Vadumee: "The Brutes control the cruiser, Arbiter. I'll remain here, make sure no reinforcements get in behind you. Then, I'm going to take the cruiser back!"

{'Vadamee walks into a room with Elites and Hunters}

Elite: "The Arbiter? I thought he was dead! Hold your fire. The Hunters have come to our aid, Arbiter. They will fight (sometimes fight will be substituted by stand) by our side.

{'Vadamee fights his way to a room where two Elite Councilors and two Hunters are being held prisoner behind force field doors}

(If the Spec Ops Elite lives at this point and follows you to the room)

Spec Ops Elite: Free our brothers! Death to the Brutes!

(Once you clear the room, free the Hunters and Councilors, then head to the top floor to the Scarab)

('Vadamee and his Elites arrive upon a group of Brutes preparing to execute the Marine prisoners.)

Tartarus (O.S.): "Mine will do, kill the others."

Brute 1: "Yes, Chieftain. (to other Brute) A day's ration says I can do this in one cut."

Brute 2: "Two cuts at least."

Brute 1: "Done. Wait, movement!"

Sergeant Major Avery J. Johnson: "Go, go, go!"

{'Vadamee turns around to see the Scarab's main cannon aimed at him}

Sergeant Johnson (O.S.): "Listen, you don't like me and I sure as hell don't like you."

{cut to Scarab's helm, Johnson at the controls}

Sergeant Johnson: "But if we don't do something, Mr. Mohawk's gonna activate this ring. And we're all gonna die."

{cut to 'Vadamee}

Thel 'Vadamee: "Tartarus has locked himself inside the Control Room."

Sergeant Johnson (O.S.): "Well, I just happen to have a key." {the Scarab's cannon opens} "Come on, Grab a Banshee and give me some cover.(focus on Johnson) They're gonna know we're comin'."

Gameplay
{Two Banshees arrive and the Elite pilots come out}

Elite: "Take my Banshee, Arbiter."''

{'Vadamee does so, Johnson fires on enemy Wraiths}

Sergeant Johnson (O.S): Ha! How do you like it?!

{they approach the Control Room}

Sergeant Johnson (O.S.): "Stay clear of the doors. Hey, bastards, knock knock!"

(If you block the doors)

Johnson(O.S.): "Stay clear of the doors!"

Johnson(O.S.): "Are you trying to get killed? Gimme some room!"

(When you don't move)

Johnson(O.S.): "What, do I have to spell it out for you? MOVE!!!

Johnson(O.S.): "Hey, listen, I'm gonna count to three. One ... Two ... Three! Don't say I didn't warn ya!"

(If you move away while he's counting)

Sergeant Johnson (O.S.): "Good! Now stay put!"

Sergeant Johnson (O.S.): "Hey, bastards. Knock knock!"

(If you go back after he says to stay put)

Sergeant Johnson (O.S.): (unamused) "Ha ha, that's real funny, I'm still shootin!"

{Scarab cannon fires, destroying Control Room's door, 'Vadamee enters the Control Room, runs into some Brutes}

Brute: "Do not let the Arbiter into the chamber! The Chieftain must complete his holy work!

{'Vadamee either kills the guards or sneaks past them, then heads into the main chamber of control room}

{Tartarus and four Brute Captains stand in front of the control panel, holding Keyes and 343 Guilty Spark}

Tartarus: "Come, human, it's easy." {he tries to get Miranda to insert the Index} "Take the Icon in your hands. (growls impatiently) And do as you are told!"

{he slams the Index on the console, which flashes red lights}

343 Guilty Spark: "Please, use caution! This Reclaimer is delicate."

Tartarus: "One more word, Oracle, and I'll rip your eye from its socket!" {he turns to Keyes, pushes her forward}

Commander Keyes: (Exhales sharply)

Tartarus: (soft menacing growl) "Which is nothing compared to what I will do to you."

{Thel 'Vadamee walks in}

Thel 'Vadamee: "Tartarus, stop."

Tartarus: (Gasps, jerks his neck up in surprise) "Impossible!"

Thel 'Vadamee: "Put down the Icon."

(Tartarus turns to face 'Vadamee)

Tartarus: "Put it down, and disobey the Hierarchs?"

Thel 'Vadamee: "There are things about Halo even the Hierarchs do not understand."

{Brutes step forward menacingly, Tartarus waves them off}

Tartarus: "Take care, Arbiter, what you say is heresy!"

Thel 'Vadamee: "Is it? (gently) Oracle, what is Halo's purpose?"

343 Guilty Spark: "Collectively, the seven—"

{Tartarus grabs 343 Guilty Spark and jerks it around}

Tartarus: "Not another word!"

Sergeant Johnson (off screen): "Please ...

''{Tartarus lowers 343 Guilty Spark to see Johnson standing next to 'Vadamee. He holds a beam rifle and aims it directly at Tartarus}''

Sergeant Johnson: "Don't shake the light bulb!"

{Brutes growl and approach}

Sergeant Johnson (raises Beam Rifle to Tartarus' head): "If you wanna keep your brain inside your head, I'd tell those boys to chill."

{Tartarus barks as commanded, Brutes back off}

Sergeant Johnson: {to 'Vadamee} "Go ahead, do your thing."

Thel 'Vadamee: "The Sacred Rings, what are they?"

343 Guilty Spark: "Weapons of last resort. Built by the Forerunners to eliminate potential Flood hosts, thereby rendering the parasite harmless."

Thel 'Vadamee: "Those who made the rings? What happened to the Forerunners?"

343 Guilty Spark: "After exhausting every other strategic option, my creators activated the rings. They, and all additional sentient life within three radii of the galactic center, died, as planned."

(Close up on 'Vadamee; he lowers his head in sadness)

343 Guilty Spark: (Off screen) "(slightly awkwardly) Would you...like to see the relevant data?"

Thel 'Vadamee: {Turns his attention back to Tartarus} "Tartarus, the Prophets have betrayed us."

{Tartarus pauses, then throws 343 Guilty Spark at Johnson's head, knocking him down, then grabs Keyes' hand and forces the Index into the console}

Tartarus: "No, Arbiter! The Great Journey has begun and the Brutes, not the Elites, shall be the Prophets' escort!"

''{Tartarus grabs his hammer as his energy shield turns on. The main platform splits into three as Halo charges up}''

''{Elite reinforcements show up and wipe out the Brute Captains. Tartarus jumps to the platforms. Johnson hangs back, firing on Tartarus with his Beam Rifle}''

343 Guilty Spark: "Charging sequence initiated. Primary generators coming online."

Commander Keyes: "Well, shut them down!"

343 Guilty Spark: "Apology. Protocol does not allow me to interfere with any aspect of this sequence."

Commander Keyes: "Then, how do I stop it?"

343 Guilty Spark: "Well, it will take some time to go over the proper procedures, I—"

Commander Keyes: "Quit stalling!"

343 Guilty Spark: "Under more controlled circumstances, I would suggest the Reclaimer simply remove the Index."

Commander Keyes: "That's it?! Johnson, I'm on it!"

Sergeant Johnson: "Hang tight, ma'am! Not until that Brute is dead!"

{After you attack Tartarus for the first time}

Tartarus (Slams his hammer on the ground): "A lucky hit. You shall not land another."

343 Guilty Spark: "Secondary generators charging. All systems are performing well within operational parameters."

Commander Keyes: "You're telling me that you cannot stop the sequence?

343 Guilty Spark: "Reclaimer, please understand that interfering with the wave generation process will severely damage this installation.

Commander Keyes: "Give me a direct answer!"

343 Guilty Spark: "I am but a Monitor. The Reclaimer can do as it likes."

343 Guilty Spark: "Power generation phase complete. The installation is ready to fire. Starting final countdown."

Sergeant Johnson: "Come on, Arbiter! Kick that guy's ass!"

343 Guilty Spark: "Firing sequence initiated. And may I say, Reclaimers, it has been a pleasure to serve you both. Goodbye."

{'Vadamee kills Tartarus}

Note that if you hit Johnson with your weapon, he will sometimes say "Easy, Chief!" or "Chief! What the hell are you doing!", "Watch it Marine", or "Get back into battle Marine", as if 'Vadamee was the Master Chief.

Normal Walkthrough
Enter the driver's seat in the Spectre (or the Wraith as the Wraith can easily destroy Ghosts with one easy short range blast) and boost through the path until you reach an open area with a cliff. A Brute-controlled Ghost or two may follow you. If so, take them out. Slowly approach the Scarab until the Phantom is triggered, then stay behind the boulders until it goes away. After it does, move toward the opposite end of the area. While Rtas 'Vadumee fires on the enemy Wraiths, get out of the Spectre and strafe around the group of Brutes before attacking from the side. This way, you can take a Brute Shot from them.

When all enemies are removed the door will open, trade your other weapon for a Carbine and follow your allies which also include hunters. After passing through the corridor, open the door to let your allies into the next room but stay behind yourself. This way, the enemy fire will be drawn elsewhere. After a moment, engage your active camo, open the door and use your Carbine to headshot the Brutes. If the Brutes berserk at you, switch to your Brute Shot. After all the Brutes are dead, trade your Carbine for a Particle Beam Rifle and head through the next door.

Creep around the bend with your active camo and use your Particle Beam Rifle to snipe enemies on the far side of the canyon. Watch out for Jackal snipers! If you run out of ammo, replace your rifle with the other one in a previous room. If you drain that one, replace it with a Carbine. When you snipe all enemies you can snipe, run to the bridge and engage active camo just before you turn the corner. There sits a Brute on a Shade; toss a grenade on him which would remove him and from the sentry gun. Wait for your active camo to charge and then walk slowly down the right side of the bridge until you engage a checkpoint. Now, a new batch of enemies should show up. Snipe what you can, but be ready to switch to Brute Shot if they come near. The hunters will not advance from here on and you will have to go on your own.

When you reach the next bridge, use a Beam Rifle to take out the Jackal sniper at the far end. Take out the shielded Jackals near you, but keep in mind that a Phantom will come and fire on you if you linger long. Just stay out of the Phantom's reach and wait for it to go away. Use the Particle Beam Rifles to snipe Drones at the far end.

In the next room, go up the ramp and switch your Particle Beam Rifle with the Energy Sword. Engage active camo, walk around a corner and use your sword to take out a Jackal, and then run back the way you came. Repeat until all Jackals are dead, then trade your sword for a Carbine. Engage active camo and head around the left side. Notice a small machine projecting a force field to seal an Elite in a cell. Take it out with your Carbine. While the Elite distracts the Brutes, free a pair of Hunters in a lower level cell. Proceed to kill the Brutes. Follow the next corridor and fight the Brutes you find outside with the help of the hunters and the elites, during the fight (if you go to the left you will notice a pair of humans behind a box aiding you in the fight) until the cinematic is triggered. Another way to free the prisoners is to go invisible, use your carbine and quickly free the Councilors or the Hunters before your camouflages fails then let your friends do the rest!

If you are low on ammo, it may be wise to return inside to collect weaponry. When you are satisfied, board a banshee which has landed and boost to reach maximum altitude. The Scarab will not be able to destroy the first three Wraiths on its own, so help it out. After they are killed, you can fly alongside the Scarab and fight the enemies that attack it, however, this is unnecessary. The Scarab can not be damaged, so you may boost through the canyon at once and simply wait for the Scarab to catch up. When it opens the door, proceed into the Control Room.

When the scarab blasts through the doors, head on through. Soon enough, several Brutes, Brute Captains and Brute Honor Guards head through the doors. Kill them or avoid them (your active camouflage can help with the latter) and head through the door to the control room. I suggest grabbing a pair of Brute Plasma Rifles to use in the upcoming fight. If you can't find two, just wait and grab the one that the Brute Captain has in the control room.

If you are low on ammo, health, or just don't want to fight the Brutes, there is a way to fly in through a side entrance, bypassing the entire fight. Another way is to throw to grenades at both sides of Tartarus which will immediately kill the brutes. An easy way to kill Tartarus is go to the top(Via the gravity lift) and gun him down from above. But there is a problem if Tartarus goes up via the gravity lift which is when you should go down. Wait till he is on the bottom level then go up and start firing down. {Cutscene}

Let the Elite reinforcements deal with the Brute Captains; there's no point fighting them and Tartarus if you don't have to. Wait for the Sarge to headshot Tartarus, then move into attack with your Brute Plasma Rifles in short sharp bursts. Don't let them overheat, as you will be defenseless. Watch out for Tartarus' gravity hammer, it will kill you with one good blow so its better to be a good distance from him. Until Tartarus doesn't glow any more, you can unleash plasma hell on him 'til he dies. It may take you a few times to get him down.

Speed Run Walkthrough
''Note: The techniques utilized in this walkthrough require correct Camouflage usage, precision and speed. This walkthrough is good for Legendary, and is based on the current fastest Speed Run at High Speed Halo, Flechette's 12:48 Legendary run. It may be altered as and when faster runs emerge.''

Take the Spectre. As soon as it's yours, activate the boost and charge straight for the first Wraith in the level, ignoring the Elite that gave it to you as well as the Brute-driven Ghosts that will pay a visit. You may want to use Active Camouflage when attempting to hijack the Wraith.

As soon as the Wraith's yours, make a beeline for the Scarab and take out the two Wraiths in front of the door, ignoring the fire from the Phantom that may attack. Now go around the right rock and assault the Brute waiting there. Get out and swap out your Plasma Rifle for his Brute Shot once he's dead. Now charge for the door. If you've been fast enough, you should get a checkpoint as you enter.

Swap out your Plasma Pistol for the Carbine and run right past the reinforcements. Once you get to the first room with Brutes, run right past them and activate Active Camouflage as you near the door. Skip the two Brutes that will run in, as well as the Brute in the turret. As you get to the other side of the chasm, you may come under fire. Use Active Camouflage once again and vault the low wall. Open fire on the enemy reinforcements with your Brute Shot, then run on. You will get a checkpoint as you reach an open-air bridge.

Jackals will arrive to greet you. Use your Active Camouflage once again to bypass them and slaughter the Jackal sniper at the end with your Carbine before he can get his deadly shot off. Then run on. If you've been following to the letter, you should get another checkpoint two rooms before the next enemy encounter.

As you reach the room with the prison cells, take the lower floor's right route and destroy the generator for the cell with the Hunters in it. Then take the left route and free the Elite Councilor. Feed the Brutes two Plasma Grenades, then head to the upper floor. Trade out your now-empty Brute Shot for the Energy Sword and free the last Councilor, then assail the Jackal waiting on the platform. As the next group of Brutes enter through the door, activate Active Camouflage and run through. You will get a checkpoint one door before the next encounter.

Back stab the Brute with his back foolishly to you, then stick the nearest Brute Captain with a Plasma Grenade. Camouflage yourself once more and stick the Brute nearest to the Scarab, then kill the final Brute with a Sword Lunge. Enjoy the cinematic if you want... Or skip it. You are, after all, on a speed run, and every second counts. Wait for the Elites to land the Banshees, then get into one. You get a checkpoint as soon as you're in the air.

Fly low to the ground as you engage the Wraiths. You will want to be close enough to the Wraiths to make them use their plasma turrets. Let them hurt your Banshee until it loses either wing, then retake to the skies and wipe them out from up high. As soon as you destroy the last of the three Wraiths, immediately start boosting towards the Control Room. You should get a checkpoint as you fly over the spare Banshee.

Ignore the Spectre charging towards the Scarab and head straight for the Control Room. If you've been boosting all the while, you should receive another checkpoint just before you go off the cliff.

Find a spot on the exterior of the Control Room and start... waiting. For Johnson to get the Scarab to the door. If you've been following to the letter and dashing madly on, the wait will take about two minutes. Watch Johnson blow up the door to the Control Room.

Here, you have two choices. Firstly, you can find the spot on the Control Room's exterior which will instantly teleport you into the final battle. If you followed this method, skip the next two paragraphs.

Or if you don't know where that is, don't despair, because Flechette didn't use it either. Fly the Banshee into the interior and head to the ceiling. Squeeze the Banshee through the hole in the rafters and down to the door. If you set off on the second method as soon as the door blew, you should get a checkpoint on the way down after squeezing past the rafters.

Get out of the Banshee and make the door open, then get back in and fly the Banshee past the Brutes that enter the next chamber, on to the next chamber.

Here is where both routes meet. Enjoy the cutscene if you want... Or not. You get a checkpoint as soon as the cutscene ends.

Leave the Brute Captains guarding Tartarus for Johnson and the Elite reinforcements that show up, and make a beeline for your Banshee. Get in and fly over to Tartarus.

It's mostly smooth sailing from here on. Simply pummel Tartarus with the Banshee Bomb and a bit of plasma fire whenever Johnson brings his shield down and dodge him as he jumps around. Luckily, he's too stupid to hit the Banshee with his Hammer. However, at times in the fight Brute reinforcements will arrive to aid their Chieftain and, ironically enough, they're not as stupid. However, they are much easier to wipe out. Feed them your firepower before they can take out your ride. Rinse and repeat until Tartarus is dead.

That's the end of The Great Journey... And Halo 2 as a whole. The current record is Flechette's 12 minutes 48 seconds. If you think you can best it, go record your own run and submit it!

Overview
Here we are...the end of the road at last, and only the Arbiter can stop the Covenant from drinking the cosmic Kool-Aid and destroying all sentient life in the galaxy. The scenery should look familiar, as this level picks up right where Uprising left off. This time, you'll begin with some vehicular combat, using a spectre (and potentially a wraith) to blast your way through a swarm of ghosts and wraiths with the aid of your invincible spec-ops buddy. You'll then move inside, where you'll battle through room after room of brutes and jackals, though this time both elites and hunters will join you. Eventually, Sarge will join the team as well, and you'll have one last vehicle battle as you close in on the control room. You may have been expecting to fight Tartarus at some point, and your worst fears will be confirmed as Bungie pulls out the last boss battle of the game.

Part 1: Your Ass, My Size-24 Hoof
Although you start out on foot a Spectre will soon arrive to pick you up. Since the spec-ops commander stubbornly refuses to give up his Wraith, the Spectre is the best we can do for the moment. (In lower difficulties, he will leave the Wraith and you can choose which vehicle you want).

Interestingly, the level starts you out very close to your ultimate destination. Any attempts to head right for the control room, though, will likely be foiled by the cheap instant death barrier down below the cliff.

Your first priority is to upgrade your vehicle to something a bit more robust, as you'll be wading through quite a few enemy Ghosts, as well as a couple of Wraiths. Thus, rather than jumping right into the combat at the beginning, I'd recommend boosting ahead a bit and procuring the first available Wraith, as shown in the next video.

The biggest danger associated with this tactic is probably being shot apart by Ghosts while you're boarding the Wraith. However, if you don't waste any time, you should usually be able to make it to the Wraith and complete the boarding before you really get swarmed. Using grenades to kill the driver can help speed up the process, though you run the risk of destroying the Wraith along with him. As your allies don't let little considerations like, say, the fact that you're clinging to the vehicle that they're firing on slow them down, there's also the danger of friendly fire. Partly for this reason (and partly to avoid getting caught in the explosion if it gets destroyed), I'd suggest parking your Spectre behind the rock before boarding the Wraith.

Once you've safely gained control of the wraith, you can relax a bit. Obliterate any Ghosts that may be pestering you and move ahead to engage the two enemy Wraiths near the door. I'd recommend attacking them more or less head-on, as shown in the next video.

Right-click (option-click on a Mac) and "Save As" to save to disk.

The small tree on the right can actually help provide a bit of cover, intercepting some of their shots. You could try flanking them from around the little hill on the right, but the narrow path severely restricts your movement, making you an easy target. Note that there's also a Phantom out past the cliff to the left who may fire on you at some point. From this distance, though, he's not really much of a threat, so I usually just ignore him and focus on the Wraiths. Take a moment to savor vaporizing the Brutes running around on foot with the Wraith's cannon.

When the area is clear, I'd suggest exchanging your useless Plasma Rifle for a Brute Shot and as much ammo as you can find before heading inside. Unfortunately, you won't run across an Energy Sword for a while, so the Brute Shot is the best you can do for melee attacks.

Once inside, proceed through the hallways, making sure to exchange your equally useless Plasma Pistol for a Beam Rifle along the way, until you enter a two-level room guarded by a phalanx of five Brutes on the upper level. A couple of additional Brutes will also enter through the upper door after you've killed off a few members of the initial group.

You might be inclined to sit back in the hallway and use your newly-acquired Beam Rifle to pick off the Brutes from a distance. The problem with that tactic is that not only is it tedious (with all of the grenades bouncing around, it can be hard to get a clear shot unless you're cloaked), but your Hunters will take a tremendous pounding, and at least one of them will most likely die. The Hunters can be a valuable distraction in the next battle, and so it really pays to keep both of them alive. Thus, I'd recommend moving in on the Brutes right away, before they can deal out too much damage. Although there are quite a few of them, they tend to focus their attention on the Hunters, which makes it much easier to sneak up the ramp and kill several of them from behind before they even know you're there, as shown in the next video.

QuickTime (2.1 mb) | WMP9 (2.1 mb)

Right-click (option-click on a Mac) and "Save As" to save to disk.

Make sure not to use your cloak too early, as you'll want to save it for when the Brutes arrive through the door. If necessary, you can also drop down to the lower level after taking out the first group. Note that, for some reason, the Brutes in the second group (even those that have gone berserk) have a tendency to retreat back the way they came when they're losing the battle, so if you don't finish them off here you'll have to deal with them in the next room. As usual, collect Plasma Grenades and Brute Shot ammo after the battle.

As you proceed through the next door into the large cavern, you'll find yourself on one arm of a U-shaped platform that curves around to the right, while five Brutes occupy the other. Another group of two Brutes, two regular Jackals, and two Jackal Snipers will arrive from the cave on the opposite side after you either kill off most of the original Brutes or you approach the exit.

The easiest way to survive this room is probably to run right through, as shown in the next video.

QuickTime (1.7 mb) | WMP9 (1.6 mb)

Right-click (option-click on a Mac) and "Save As" to save to disk.

Jumping the chasm at a couple of points helps to speed things up and bypass the brute in the turret, though sometimes you may end up taking quite a bit of fire from the main group. Be sure to save your cloak for the end, as you'll need it to avoid the snipers.

Despite the effectiveness of this tactic, I'd recommend fighting this battle merely because it can be rather fun. If you've been following my advice, you should be carrying a full sniper rifle, and so it's certainly possible to sit back and snipe everything. However, closing in on the enemies right away can work just as well for killing them all as it does for avoiding them. If you're quick enough, you can manage to get around behind the second group while they're still mostly bunched up, as shown in the next video.

Otherwise, if the second group manages to disperse, you'll just have to take out the first group and then approach the remaining enemies in whatever way seems best, as shown in the next video.

Note that you can always crouch jump over the low wall in order to flank the enemies, when necessary. Whatever you do, I'd advise against standing around in the vicinity of the turret brute. There are several exploding objects nearby that are easily detonated by brute shots and possess a dangerously wide kill radius.

Continuing onward, you'll reach a short bridge defended by several nearby jackals, as well as a jackal sniper and several drones at the far end. The next video shows how I usually approach this battle.

Note that a phantom will appear on your left to complicate matters when you're about halfway across, so once you start moving I wouldn't stop until you're safely out the other side. In my view, there's not much to be gained from fighting the drones except pain, so I'd recommend running right past them. The timing of your cloak is very important here, as the drones will send a barrage of plasma fire your way if you wait too long, which will usually cancel your invisibility.

Continue up the hallway and into the prison.

Once again you'll have to deal with two large contingents of brutes, with the second group showing up, as usual, when enough members of the original group have fallen. Three jackals also lurk up on the walkway around the center of the room. Despite the large number of enemies, though, a relatively mindless tactic is all that's really necessary to clear the room, as the next video shows.

It's very easy to die if you take too long to fire a burst of needles, as the brutes will quickly start launching grenades and shooting carbines your way. The Needlers tracking is pretty forgiving, though, so you won't have to aim too carefully; but don't forget to use your cloak when it's available. It's possible to free your captured allies from prison during the battle (just shoot the little force field emitters in front of the cell doors). However, they won't last very long with all of the brutes around, so I usually don't bother. Note that the door by the brutes will stay locked until the second group arrives, so even if you're planning on just running through the prison, you'll still have to kill at least a few of the enemies.

When the battle is over, I'd suggest picking up the energy sword if you haven't already and exchanging your Needler for the beam rifle. Fill up on grenades, and free your allies as well, though they won't be able to help you for very long.

Continue through the next hallway, which eventually leads you to a large platform outside. There are four brutes here, and the next video shown how I usually deal with them.

Part 2: Backseat Driver
When the cutscene ends grab a banshee to begin a fairly long sequence of vehicular battles. Make sure that you have at least one plasma grenade left before you leave, as it will become very useful the next time you're fighting on foot. The terrain should look rather familiar from the beginning of the level. Regardless of what your objective says, the scarab is just as indestructible as it looks and you don't have to worry about protecting it. In fact, you can skip as much of the combat this chapter as you desire, as the scarab will eventually kill the three wraiths and then lumber onward to its ultimate destination.

Still, as long as you're waiting you might as well make yourself useful and speed things up. The safest way to destroy the wraiths is probably with the banshee, as it's quick enough to dodge their slow shots with relative ease. However, if you intend to keep fighting after the Wraiths are gone, you'll also have to face two Spectres and four banshees around the next bend. To make matters worse, several enemy turrets line the canyon walls. Surviving this gauntlet in the banshee can be fairly challenging, and so you'll be better off in the long run if you can take control of one of the Wraiths. I'd suggest boarding the one on the right and using it to take out the other two, as shown in the next video.

You should receive a checkpoint after this battle, and I'd recommend that you save and quit before proceeding.

The two Spectres will arrive as you move a bit farther along the canyon. They can be fairly annoying, gradually picking you apart with their little cannons, so I'd suggest taking the proactive approach and going right after them, as you'll be less likely to miss at close range. When the Spectres are gone, four Banshees will fly over the cliff ahead of you one at a time. The next video shows how I approach this battle, using the Wraith.

Staying near the corner along the side of the cliff forces the Banshees to begin their attack runs closer to you, making them somewhat easier to hit. As you can see, their tendency to fly straight at you does not exactly help their cause, either.

By the time you finish with the Banshees, the scarab will most likely have reached its destination. If you're really out for blood, you could take the time to destroy the two wraiths and four banshees in the next area, but I generally just head for the door at this point. I'd also recommend that you save and quit before proceeding if you received a checkpoint after destroying the banshees. I'll note once again that it's possible to skip this whole section simply by hopping back into a banshee after clearing out the first three wraiths and flying right to the control room. You can wait there out of harm's way until the scarab shows up. You'll have to fly toward the scarab close enough that Sarge begins firing on the control room door.

Part 3: Delusions and Grandeur
After the door is destroyed, the intended path for you to take is clearly to land outside and proceed on foot. You'd then have to fight through a large group of brutes before finally arriving at the control room.

However, it's actually possible to squeeze your banshee through the tunnel and fly over the brutes and into the control room. This approach has the advantage of not only bypassing the difficult battle with the brutes (though they can still potentially shoot you down), but also allowing you to employ the banshee in the final battle with Tartarus. In order to get the banshee through the tunnel you'll have to squeeze it up and over the rubble once you're past the doorway. You can make this task somewhat easier by destroying one or both of the banshee's "wings".

There's an even more interesting way into the control room, though, that involves exploiting a glitch whereby you can trigger the cutscene that precedes the final battle from outside the control room structure (thanks, Kyle Barr!), as shown in the next video.

As you can see, not only is this method quicker, but it also allows you to skip the brutes entirely and, surprisingly, even warps the banshee inside with you. Well, most of the time, at least. It's been my experience that the banshee doesn't always make it through in working condition (for example, I've run back to find it stuck in the floor). It's for this reason that I encouraged you to save and quit at the nearest checkpoint before you entered the control room structure. Be aware that you can't enter the control room in this manner until Sarge breaks down the door and the final chapter transition occurs, so there's no sneaking in early. Also, if you don't already have a beam rifle I'd recommend stopping by the bridge and picking one up before you proceed. You may not even end up using it if you have the banshee inside, but it gives you more flexibility for deciding how you want to deal with the brutes in the final battle. Anyway, it's not like you have anything else to do while Sarge is breaking down the door.

And so we come at last to the final battle of our epic, galaxy-spanning quest.

The Arbiter vs. Tartarus

In light of this momentous occasion, Bungie added a entirely new weapon never before seen in the Halo universe, the gravity hammer. Tartarus wields this formidable weapon against the Arbiter in their final encounter.

Unfortunately, Tartarus is one of the easier of the three bosses(assuming that you don't use the fuel rod gun tactic on the Heretic Leader, at least). In contrast the other two bosses, Tartarus doesn't have a ranged attack, and so he can't hurt you as long as you don't let him get to close to you. His henchmen, meanwhile, attack only from one direction and only at fairly specific times during the battle. Thus, you can see them coming a mile away and there's little chance of being surrounded or taken by surprise.

The structure of the battle is fairly simple. Like the other boss fights, I tend to think of it in terms of several rounds, with each round ending when Sarge knocks out his shield and you damage Tartarus. Depending on your weapon choice, you'll probably need somewhere in the vicinity of 8-10 rounds to kill him. So, as far as Tartarus himself goes, the battle basically amounts to maneuvering to keep him at a distance until Sarge gets his shots in and you can do a bit of damage.

The only breaks in this pattern occur when the brute reinforcements show up. Although the time of their appearance does not appear to be absolutely fixed, it's at least consistent to a pretty high degree. The first group almost always appears after you first damage Tartarus (he'll say "A lucky hit. You'll not land another"). Expect the second group to arrive about 2-3 rounds after that, and the third group after another 2 rounds or so. As long as you keep an eye on their platform, you should be able to see them coming long before they actually get close enough to present a threat.

Given an understanding of the basic structure of the battle, the issue then becomes the specific tactics for damaging Tartarus and eliminating his brutes before they can cause you trouble. As I mentioned earlier, potentially clever shortcuts like pushing him off the platform into the abyss or smashing him with the banshee won't work, so you'll have to do it the old-fashioned way.

First and foremost, I should point out that the easiest and quickest method is to rely exclusively on the banshee. In that case, all you need to do is hover around Tartarus until Sarge takes out his shields and then blast him with the fuel rod cannon, flying off to interdict the other brutes as necessary. As Tartarus won't even be able to reach you, victory is almost assured, as long as one of the other brutes doesn't get in a lucky shot with a grenade or something.

Of course, the battle is quite manageable even without the banshee. Personally, I prefer to fight Tartarus on foot simply because I think it's more fun, and use the banshee only to take on the rest of the brutes.

Perhaps the most important observation if you intend to forgo the banshee at any point is that although the battleground consists of three platforms, virtually none of the action will occur anywhere but the middle platform. Tartarus may fall down to the lower level or use the beam in the middle to ascend to the top, but given a bit of time he'll always return to the middle. Likewise, both the brutes and your useless elite allies will jump to the middle level and stay there. Thus, the top or bottom levels (I always choose the top) can serve as a safe refuge and an ideal drop-off point for weapons and your banshee where nothing is likely to disturb them.

As far as weapons go, I'd recommend dual brute plasma rifles. They'll do a tremendous amount of damage in a short period of time, and you'll never have to worry about running out of ammo. The shotgun works well, provided that you have enough ammo. The sword, for a change, is highly ineffective and puts you at great risk every time you get close to Tartarus. The carbine and brute shot, for their part, suffer from ammo limitations and just don't seem to deal as much damage as the plasma rifles or shotgun. As for plasma grenades, his shield is usually back up by the time they explode. You may be inclined to try knocking out his shield yourself with the beam rifle in order to speed things up. While it's certainly possible to do so, I've never really found it to be worth the trouble, as you'll quickly run out of ammo and you won't have much time left to damage him after switching weapons. In my experience, you're better off just sticking with the plasma rifles. However, the beam rifle can be very useful if you don't have the banshee (or are choosing not to use it), as you can often snipe several of the brutes before they even make it to the central platform.

Since you'll need to wait for Sarge to dispel his shield in each round, I'd recommend maneuvering Tartarus into a location where Sarge can get a clear shot, without any obstructions. Your best bet, perhaps not surprisingly, is around the outside of the middle platform right in front of Sarge's position.

As an alternative method to avoid Tartarus' hammer, take the Needlers off one of the elites that spawn (if he doesn't spawn then revert to saved until you get one). Then jump on the platform with Miranda and 343 GS on and attack Miranda with the Needler until she has taken enough rounds for them to explode, she will then run forwards and hold an imaginary gun. As she is invincible she wont die when Tartarus attacks her and he wont leave until she is dead (which is impossible). Hey presto the battle is easier.

With these considerations in mind, the next video shows an example of such a battle.

As you can see, nothing really fancy is required. Just be patient and deliberate in your movement, taking care to keep Tartarus in an advantageous location and to watch for approaching brutes. Keep in mind that he can strike both forward and backward (like the hunters), so be sure to stay a safe distance away from both sides of him. I'd also discourage you from trying to jump over his head. One move you can use to fake him out, though, is to hesitate slightly when backing away from him (much like you could do with the hunters in Halo 1 to trick them into lunging and exposing their midsections). This feint will trigger his melee attack and allow you to put a bit more distance between yourselves.


 * Note*: An alternate method of bringing Tartarus down is to wait for Johnson to take out his shield, and then shank him.  Right as Tartarus first jumps onto the platform, several Elites follow, all carrying energy swords.  Once they are taken out, take one of their energy swords and lunge at Tartarus with the sword once his shield is down.  In my experience, if you're playing multiplayer, have one person distract him so that the one with the sword can get at him from behind.

That's what he gets for bringing a hammer to a gunfight.

Be aware that you won't get a checkpoint at any time during the fight, so don't let up and get careless at the end.

When you're done, sit back, enjoy the ending cutscene, and revel in your legendary victory.

I don't know about you, but despite all of our hard work I sort of wanted to see the Halo fire.

Congratulations!

Trivia

 * If you play through Uprising and High Charity, the weapons the player carried in Uprising will appear with the Arbiter in the Great Journey. In this way, you can get a Rocket Launcher, Frag Grenades, or a Fuel Rod Gun early on in the mission, although the Fuel Rod Gun may not appear sometimes.
 * It's possible to skip straight to the Control Room battle after the Scarab escort. Fly the Banshee around the large sphere and the cinematic will start. It may take some time to get the Banshee in the right position but it will happen. Note: You may also get to use the Banshee in the fight.
 * It is also possible to use a Spectre and a Ghost against Tartarus. See here.
 * After the scene where Johnson steals the Scarab, if you fly down to the entrance, a random Elite will appear that has different armor. This may be Rtas 'Vadum's replacement. This Elite will not help you fight though unless you get a Spectre and drive up to him.
 * If you are able to drive a Ghost up to the Scarab you can get on it before Johnson. You will be able to follow him to the inside of the Scarab and see that the weapon he holds is actually a Plasma Pistol.
 * It is possible to fly the Banshee into the control room after Johnson blows the doors. If you fly it into the main chamber the cut scene will begin. However when the cut scene finishes, you must go back into the hallway where you can find the Banshee you flew. This Banshee can also be seen in the cut scene if it is landed in the right place.
 * It is possible to get a Banshee into the control room in perfect condition. Instead of going through the halls, once you enter there is a hole immediately above you which you can fly your Banshee through with no damage at all. This trick requires you to boost upwards and do barrel rolls in order to get past the wreckage. You should just skip the room filled with Brutes by boosting through them as they enter in order to receive no damage.
 * Occasionally Corporal Perez will appear instead of Marcus Banks.
 * It is possible to force Tartarus off the platform to fall to his death, but he will reappear and fall from the sky back onto the platform.
 * If you stick Miranda so she jumps on to the platform, (She is on second sky platform that comes around)Tartarus will usually focus his attacks on her, which will make fighting tartarus A LOT easier.
 * When the Phantom with the seventh Wraith comes in for deploying, you could actually land on it and then have it drive beyond Delta Halo's Control Room and drive to a far canyon, if you stay on it later it will disappear and it takes a long time to head back.
 * When you get to the beach and go too far by the side of the mountains with a Banshees you get pulled back but when you are walking it will let you explore.
 * If you have the Sputnik skull on, you can get on top of the Scarab and look inside it when it is parked at the beginning.
 * If you are able to keep your Hunters alive after the fight with the Phantom on the bridge and take them to the next room with the cells holding the Councilors and the Hunters, the Hunters in the cells won't be there.
 * At the beginning of the Tartarus fight, it is possible that there are only 3 Brutes with Tartarus, even though another Brute will appear out of nowhere when the Arbiter arrives.
 * If you manage to get a Wraith or a Ghost to the Forerunner building underwater, you can explore the mountains with it.
 * When Johnson's Scarab arrives in front of the Control Room's door, you can see a Brute with no weapons standing on top of an overturned Wraith, he will not attack you when you get close to him and will only follow you around saying random Brute taunts. It will also appear if you hijack a Banshee close enough to the ground.
 * It is possible to get Rtas 'Vadumee and the other Elite to go with you into the building. Get Rtas 'Vadumee and the Elite into the Spectre and drive it into the building then get them out. They will usually follow you, though this could take a few tries.
 * After Johnson blows away the control room doors, Brute controlled Banshees will begin to appear, in pairs. If you hijack one pair, another will arrive. You can do this indefinitely to have an infinite amount of Banshees, and Brutes, if they are hijacked close enough to the ground.
 * If you have the Banshee inside the control room and fight Tartarus he will ignore you and this allows you to get an easy kill.
 * It is entirely possible to get 4 Johnson's in the fight with Tartarus. Just take the Spectre to the control room. After the cinematic is done, go back to the Spectre and kill the Elites that should already be sitting in the Spectre. (They shouldn't be able to move the Spectre) then go back to Johnson and he will get inside the Spectre. Then move the Spectre a bit towards the control center, and there will be a replacement Johnson waiting there. Move closer to him in the Spectre and he will get in. Repeat to get a maximum of 4 Johnsons. (3 in Spectre, One sniping on the "bridge".) This will make the battle a lot more easier having 3 Johnson's being able to snipe for you.
 * There is also a hidden assault cruiser in this level near the skull. Head to the mountain and keep going around till there is a drop. Look around and it is up in the sky. You can't see it any where else.
 * If you manage to get on the place where Miranda Keyes was standing, you might able to see her crouch and hold her hands up as if she was holding a weapon. Also, if you stare at her long enough, she might call you Chief.
 * The second easiest way to kill Tartarus would be to get two brute plasma rifles from the boxes near the central lift thing and fire both at his head as soon as his shields are down.
 * If you take a Ghost to the end of the level, drive it into the water so it's completely submerged, and shoot up, the water will splash upside-down. This may also work in Outskirts.
 * You can "kill" the Sarge and Miranda Keyes with a Needler. When you fill them up with needles, they will run off the edge. However, they will re-spawn after a few seconds. If you want to do this to Johnson, you must wait until he is on the end of the platform.
 * If you use the above glitch to push Keyes off in the right way, she will land on the platform that the boss fight takes place on. She will just stand aimlessly, and will be immune to Tartarus' hammer.
 * It is possible to get Johnson in the final battle by taking a Spectre to the control room.

Mistakes

 * Brute-piloted Ghosts will have normal Plasma Rifles, not the Brute version.
 * If you land the Banshee in front of the door, Johnson will repeatedly tell the Banshee to move, as though you were in it.
 * In the ending cutscene, Miranda Keyes is shown holding a Plasma Pistol. Also, she can be seen using it during the fight, however, the weapon is not seen, and she does not fire it (the most she does is crouch and aim it).
 * Before the battle with Tartarus you can see an Elite skull on his shoulder during the cut scene but it disappears during battle against him.
 * Walking up to Banks and Stacker, Stacker will say something like, "Chief! Glad you could make it!" in the same way that Johnson does.

Easter Eggs
When you get to the part when Johnson blows up the door, fly down to see a flipped wraith with a Brute on it. He does not have a weapon and he does not kill you. If you flip the Wraith over and get in, he will begin hijjacking your Wraith. If you get out he doesn't get in. He just stays. Sometimes he follows you, and sometimes he attacks you. (Doesn't matter what Difficulty.)
 * The Black Eye Skull can be found on this level.
 * There is an Elite Minor with black as a secondary color that lands on the ground under the Scarab, 2 minutes after it blows off the door. It will randomly say things like, "We should have had a run at the Demon, eh, Arbiter?" and some other tidbits about Installation 04.
 * There is a Heretic Banshee that is an Easter egg on this level, but no Heretics appear. Also, there are times where you will find the body of a dead Elite.
 * If you look at the Elites who give you the Banshees you will notice that when they walk into the structure, they walk backwards. (They seem to look like they're walking forward though)
 * Originally there was going to be an Easter Egg in which Johnson would ride 343 Guilty Spark in different ways on different difficulty levels.
 * If you stay in the battlefield after Johnson blows open the door with the Scarab, after a few minutes a Phantom will drop off a new Wraith for you to face.

Miscellaneous
When you get to the part when Johnson blows up the door, fly down to see a flipped wraith with a Brute on it. He does not have a weapon and he does not kill you. If you flip the Wraith over and get in, he will begin hijjacking your Wraith. If you get out he doesn't get in. He just stays. Sometimes he follows you, and sometimes he attacks you. (Doesn't matter what Difficulty.)
 * Johnson's Beam Rifle is the only weapon in Halo 2 you cannot trade with because this weapon can take out the shields that Tartarus uses.
 * When escorting the Scarab you can get your Banshee stuck in the Scarab, and since the Scarab is invincible, you don't actually have to defend it.
 * When fighting Tartarus if you stay on the platform where Johnson is, Tartarus will often taunt you for example he will say, "Just like the rest of your kind. You're cowardly and weak!" or, "Want revenge? Well here I am!"
 * This is the only level where Councilor Elites are your allies.
 * Originally, there was a cutscene at the part of the level where you are on the Scarab platform in which there was a gathering of Brutes decapitating Marines. Joseph Staten explained that this cinematic had to be cut because at that time "real world events" made this a little politically dangerous.
 * This is technically the first level in which the Elites and the UNSC fight alongside each other, and the only level in Halo 2 in which they do, though very briefly and it is just Sergeants Stacker and Banks armed with Plasma Pistols against Brutes, so their impact on the battle is minimal to none.
 * Sergeant Banks and Sergeant Stacker will disappear right after the cutscene. They probably entered to the Scarab with Johnson. However, if you kill any of them, their corpses will not disappear after the cutscene.
 * For the most part, the Elites are pretty much useless when you fight Tartarus.
 * This is the only level in Halo 2 where Johnson is the only human to call the Arbiter by his title name.
 * While playing the level and see on top of the mountains you could see the parts of the Uprising level when you go outside.
 * When you start the level, go to the door you came from, then go to the tree that’s the closest, on the mountain look to your right it looks like the upper face part with eyes.
 * There is a rooster head by the trees at the beginning where you appear by the Uprising door.
 * If you try to get in the Scarab to see Johnson drive it after he is inside, it is blocked by a visible Energy door.
 * At the end cutscene where 343 Guilty Spark is talking with Johnson and Keyes, you can see Elites you managed to save during the battle with Tartarus.
 * Bungie employees impart the title as the structure at the end of the level in which you fight Tartarus as the 'Birthday Cake of Doom'.
 * For the Tartarus battle, it is often a good idea to bring a Beam Rifle along with a weapon of your choice as you can take out Tartarus' shields rather than wait for Johnson to do it, though the time is significantly less.
 * This is the last level in the Halo trilogy where you get to use a Brute Plasma Rifle, Spectre, Heretic Banshee, duel wield Needlers, a Scarab that's on your team, and play as the Arbiter in a single player campaign mode.
 * After this level it is unknown what happens to the Fist of Rukt. It might have been destroyed by the elites in disgust since it took the lives of many elites.
 * Tartarus will not die if you melee his back after his shields are gone, however, he would take more damage if you shoot its back, as most of his armor are in front of him.
 * It seems that the Beam Rifle Johnson uses is stronger than most, even on Easy difficulty, if you are in his line of fire, it will take down your shields in a matter of seconds.
 * In the part where you rescue the 2 Councilors and Hunters, whenever they are hit a lot, the Councilors go berserk and pull out an Energy Sword and charge to the enemy. An Ultra Elite in the Scarab in the level Metropolis does the same thing when Chief fires at him.
 * Nobody technically knows what Gravemind's questions to Cortana were.
 * If you fight Tartarus long enough, Brutes will jump down to the platform to aid him. Sometimes in the cutscene after, they will just be standing there watching the characters.
 * When you have a banshee, there is actually a grav-lift on top of the Scarab that if you land a banshee on, it will float in midair. No matter how you land it, it will always re-align itself to a certain position. The walkway that goes on top of the the scarab makes it look like that a banshee would be put there for an escape craft from a Scarab about to blow up.
