Part 01: Outskirts
(Three Pelicans rocket away from In Amber Clad, jet engines thundering, and spear out towards New Mombasa. The Assault Carrier hovers high over the city, Gravity Lift engaged.)

Cortana (Radio): The message just repeats. 'Regret, Regret, Regret.'

(The Master Chief watches from the stern of a Pelican as the clouds roll by below.)

Commander Keyes (Radio): Catchy. Any idea what it means?

Sergeant Johnson (Radio): (as the dropships approach the outskirts of Mombasa, passing over a convoy of Warthogs) Dear Humanity... we regret being alien bastards. We regret coming to Earth.

(Inside the cockpit of the Pelican, Johnson leans against the bulkhead behind the two pilots.)

Sergeant Johnson: And we most definitely regret that the Corps just blew up our raggedy-ass fleet!

Pilots (in unison): Hoo-rah!

Cortana (Radio): Regret is a name, Sergeant. The name of one of the Covenant's religious leaders. A Prophet. He's on that carrier, and he's calling for help.

(A Marine sniper/spotter team lies prone on a rooftop, and the Pelicans pass over their position.)

Marine (Radio): Immediate; Grid kilo 23 is hot. Recommend mission abort.

Pilot (Radio): Roger, recon. (To Sergeant Johnson) It's your call, Sarge.

Sergeant Johnson: We're going in. Get tactical, Marines!

Lord Hood (radio): Master Chief, get aboard that carrier, and secure the Prophet of Regret. This is the only place on Earth the Covenant decided to land. That Prophet is going to tell us why.

Pilot: Thirty seconds out... stand by to... whoa...

(The pilot goes silent as a huge walking tank comes into view. Its leg spears a bus, and then its main gun focuses and fires, giving the lead Pelican a glancing blow. The two other Pelicans veer off, plasma turrets on the tank's bank tracking them. The lead Pelican flips inverted, hits a building, and slides through a low brick wall, before blacking out the frame.)

(Your view is blurry, and Cortana fakes tapping on your visor)

Cortana: Hey... wake up.

Sergeant Johnson: Shake it off, Marines. Clear the crash site. Go, go, go!

Part 02: They'll Regret That Too
(As you arrive at a bombed-out building and a firefight breaks out)

Marine 2: Secure this area!

Sergeant Johnson: If they didn't know we're here before, they do now.

Sergeant Johnson: Yep. Here they come! Up high!

{After the first wave of Covenant forces are killed}

Sergeant Johnson: More on the street! Left side!

{After the second wave of Covenant are killed}

(Jackals come around a corner)

Sergeant Johnson: We got Jackals in the courtyard!

(Later, A group of Drones flies into view)

Sergeant Johnson: Buggers, headin' over the rooftops!

{Another wave of Covenant attack}

Sergeant Johnson: Across the street! Down low!

(Later, The sound of Phantom engines drifts over the rooftop)

Sergeant Johnson: Eyes up! Phantom's back!

(Later, another Pelican arrives, hovering over the courtyard)

Pilot 2 (Radio): My girl's a little big for that courtyard, Sergeant. I see a good LZ on the other side of these buildings. Meet you there, over.

Sergeant Johnson: Copy that. Someone get a satchel on the gate!

(A pair of Hunters breaks through the gate)

Cortana: Hunters.

Sergeant Johnson: Stand back, Marines. Let the Chief show you how it's done.

(Once the Hunters are down)

Cortana (Radio): Second squad, this is Cortana. What's your status, over?

Marine 3 (Radio): We're operational Ma'am, barely. Our pilots didn't make it.

Cortana (Radio): Find a hole, stay put. We'll come to you.

(When you reach the far courtyard, a third Pelican drops in and unloads Marines.)

Commander Keyes (Radio): Sergeant, I need you on that bird.

Sergeant Johnson (Radio): Ma'am?

Commander Keyes (Radio): My Pelicans are going to start airlifting armor and reinforcements into the city. They'll need an escort that isn't afraid of a little hostile ground fire.

Sergeant Johnson (Radio): Understood. I'll keep an eye on 'em. Chief... good luck.

(Johnson climbs aboard the Pelican and dusts off)

(Once you reach the second squad's position)

Marine 3: Chief! Glad you could make it. Crash site's on the other side of this hotel, Chief. Covenant are crawling all over it. Follow me.

(As you move into the darkened hotel)

Marine 3: Stay outta sight.

(A Marine pulls up in a Warthog, honking the horn)

Marine 3: Special Delivery from Commander Keyes, Cheif.

Cortana (Radio): That bridge is the most direct route to the city center.

Part 03: A Day at the Beach
Marine 3: Oh man, I love the beach...

Marine 2: I hope you packed a suit, mate!

Cortana (Radio): Cut the chatter... we got trouble.

(As you negotiate the beach)

Commander Keyes (Radio): Chief... the carrier just launched a wave of pods. They're inbound on your position.

(Covenant Orbital Insertion Pods slam down on the beach all around you, and armed Elites spring from them)

Cortana: This tunnel leads up to the bridge. It's full of rats if you know what I mean, but it beats swimming.

(As you move into the highway tunnel)

Cortana: I've been analyzing the Covenant tactical chatter. They're surprised, confused... I don't think they expected us to be here. Not... you and me, all of us... humanity, on Earth. Odd, I know, but it does help explain why they came here with such a small fleet.

Part 04: Speed Zone Ahead
(When you come across a group of Shadows in the tunnels)

Cortana: The Covenant must be trying to regroup. Don't let them.

(Once you approach the exit of the tunnel, the level transitions)

Normal Walkthrough
This is my favourite level, and the first bit is excellent fun on Legendary. But, as your a NOOB, doing it on Normal, I'll do a very accurate walkthrough for you. You'll start off this level with the well balanced array of the SMG and the Battle Rifle, and I would recommend keeping them for this first part. DO NOT TAKE JOHNSON'S SNIPER RIFLE! He is an excellent shot, and will be useful on may occasions, and can engage enemy snipers (only on Heroic, though). Keep your Battle Rifle out for the moment, and run round the corner, where a curious Grunt is investigating the crash. We have an old Earth saying here: curiosity killed the cat! DO NOT SHOOT! It will alert the Covenant in the courtyard. Melee attack him before he can alert his little friends, then run through the door and take cover behind the grey storage container to your right. Headshot the Grunts across the courtyard, forget the Jackals for a bit, and instead aim your rifle above the doorway to the stairs, where a chunk of wall is missing. You will see the Grunts before they see you, as their little rebreathers will come bobbing above the wall. When they come into sight, headshot the cute things, reload, and move to your right, towards a white bus. A pair of Jackals are here, and will make tricky targets when they have their shields up. Either run in and melee them, or shoot their hand, and then their head as they flinch. SMG time! Pull out your full-auto weapon and run through the entrance now on your left. An Elite will jump down, but the Grunts, dismissing such hooliganity (is that a word?) will use the stairs. Mow down the Elite first with close-combat fire, and the Grunts will panic and run. Mow the things down before they can escape through the door, and climb the stairs switching to your BR. An Elite will appear on the roof of a building to your right. An usually the Marines will concentrate their fire on him. Kill him before he can jump onto your platform, and you have secured the area... For the moment (puts finger to mouth). This platform you are now standing on is an excellent vantage point, and the Marines will generally stay on the second floor. Johnny with his little gun will run up to the top floor to go sniper. First, you will need to know what is here at your disposal. At the base of one of the staircases there is a weapons cache that has an SMG, a Magnum, (for you cowboys) BR ammo and Sniper Ammo. Additionally, there is an SMG cache to the left when you are coming through the doorway to the staircase. Grenades and SMG ammo can be found down next to the 2 Military Containers, remember this, as it will come in handy as your supply drops. There is a turret on the edge of the balcony, which will come in handy in several scenarios. There are two tactics that can be used to get back up to the balcony ASAP. The first is a large white truck below the turret. With a crouch jump you can make it. The second is a purple Covenant container just below where you sniped those Grunts off the roof, and with a crouch jump you can get back up to the balcony. This is a place where grenades will come in very handy, as waves upon waves of Covenant will come out of cramped alleyways set along the road, just waiting with shining eyes for an armed M9. The Marines know this, and will frequently toss bombs down on the Covie's heads, which is very useful. So here you are, waiting for a Pelican to show up and help your sorry ass, while waves upon waves of Covenant deluge you. Use your Battle Rifle for medium to long range, then switch to your SMG if they get up close and personal. You'll have to face several waves of little bastards and big bastards (to quote that Malta guy), and a squad of Elites and Jackals that will run from the door that you came through. With the latter group, try to get a frag in before they can get through the door, and stick the Elite if possible. If you missed that opportunity, jump into the machine gun and take out some aliens, then jump down to polish them off. After the Jackal patrol have been busted, turn around and use my Container-Jump technique to get back up to the turret ASAP. Do it fast, as Drones are about to appear in the line of sight of the turret. Hop into the machine gun and swat those bugs as they pop their ugly insectoid heads over the top of the wall. Watch out for the bugs to the left up high. When you have Mortened the Drone assault, take cover under the canopy as a Phantom appears, firing at you with it's Plasma Guns. Take cover until it is hovering over the top of the courtyard. Then rush to the turret and gun down the Covenant as they drop. You highest priority is the Grunts as they will toss plazzies up at you, and might stick you and you precious machine gun! Okay, so hit the Grunts as they drop, and the plazzy they were arming will be dropped under the feet of the Elites. It will weaken the Elite's shields, so push your advantage, and hit 'em while they're down. As this battle is going on, another Jackal Patrol will attack from the same door as before. Ummm... Just a minute! Finish off the last of the split-lips, then take out the Jackals and their Elite personal trainer. Ah! You've finished defending this area! The Pelican is here, and will finish up anyone you missed with it's machine gun. But don't play air guitar with your Battle Rifle yet, there is one more, um... "tiny"... problem... You have about half a minute to do this, so do it fast. Go and swap your BR for Johnny's Sniper Rifle, and jump down in front of the door. You will have one chance at this, so don't screw up. The door will break open and a pair of Hunters will walk through, with their bellies exposed. Fire two rapid shots into each of their stomachs. If you ain't such a crack shot, jump (last time, I promise) into that damn turret again and mow down the worms as they walk through. But where's the fun in that? Don't let the Hunters go into combat mode, as they will run through and slaughter the Marines. Finally! You've finished! Just the rest of the level to go... Damn... MONTAGE! Grab some guns before running through the doorway. Definitely a Sniper Rifle, but grab an SMG or BR. I recommend SMG. There are Drones and close combat coming up. Grab full ammo for your weapons (there should still be plenty left) and run through the door. There is a sniper across this courtyard (The only thing worse than Jackals, are Jackals with sniper rifles!). Take him out, and the rest of his scummy mates. Sarge will now have to leave you in a Pelican. *Sniff* bye-bye Sarge! We'll miss you! Ah, he sucked anyway. If you don't have three Marines, the Pelican will give you a refill. Move forward, but DON'T GO ROUND THE CORNER YET! Swap your sniper for a pistol, (temporarily) and pick up one of the less supplied rifles on the ground, and give it to a Marine (Thanks Chief!), then swap that crappy pistol for the fully charged Beam Rifle on the ground. The Beam Rifle owns the Sniper in this bit, cause you have to reload with the Sniper, and not the Beam Rifle, which is an excellent advantage in this particular exchange. You will now come across the fabled Sniper Alley, named after a location in the Cold War, I think it was. Oh well, this is Halo, and this bit sucks on Legendary. In front of you a Jackal will walk from behind a container. Headshot the bastard. For ease, here is a list of snipers in this part.


 * 2 at the other end of the alley, in the second and third floors of the broken building
 * 1 to the left of the explosive Grunt Methane supply container.
 * 1 up on the top of the building to the left
 * 1 on the top of the building to the right

That's alotta snipers... While you trade fire with the snipers, Drones will fly in to cause trouble. If you're good, you can snipe 'em outta the air, or when they land. Additionally Jackals will attempt to storm your position. What of the Marines? The Marines, being the tactical masterminds they are, will crouch in the center of the alley not moving, and are pickoffs from sniper fire. On maybe Heroic and definitely Legendary, they're screwed. Give the stupid twits covering fire, but be wary of the Stealth Elites that will leap out as you move forward on Heroic and Legendary. One has a Plasma Sword, so look out! Once you have cleared out sniper alley, go back and drop the empty Beamer for your old Sniper Rifle, and continue on to the left. Watch out for the Jackal that appears on the bridge thing above your head. At the other end of this alley, two snipers will jump out and attempt to make your head a family heirloom. Make their's a sellable item on Ebay (slightly damaged) and continue forwards, looking out for the sniper in the narrow alley up to your left about halfway down. Watch out for an Elite that may jump out from where the two snipers were. He will run forwards, attempting to rifle you. Rifle him first, then continue on into a carpark place thing. You will be attacked by two waves of Elites and Grunts, and a sniper will appear on the shingled rooftop to give you some grief. Survive this wave, then move forwards, on to Hotel Zanzibar. Aaahh! Hotel Zanzibar! An excellent place with nice rooms, a swimming pool, and homocidal aliens! A couple of Grunts and an Elite (an Ultra on Heroic and Legendary) will be laying seige to some Marines hiding in the reception area with Plasma Cannons. Take out the aliens, and Sergeant Stacker will walk forwards to greet you, if he didn't DIE. Hey, he changed quick! Didn't he have ODST armour? Oh well... Move through the hotel. Hmmmm, a bit dark for my taste, but don't switch on your light. It ain't needed. For some reason, an Elite will fire his Plasma Rifle in front of the door, giving noobs a nice warning of the oncoming danger. Leave off throwing a grenade around the corner until the next section has loaded, or the grenade will disappear in midair. Loading... done, okay NOW you can nade 'em. Throw to your hearts content, then rush forwards, veering to the left to pick off a pair of Grunts. You are now in the place where the adventures of Another Day at the Beach occured. Hmmmm... Decomposition is getting mighty fast these days... No time to contemplate! A Phantom is coming! It will drop a squad of Grunts and an Elite on the bridge above the road. They will rush forwards, apparently unaware of the methane tank in their path... Toss a grenade at them when they pass, to see some Grunts fly. Mow down the Elite, and jump down onto the road as a Warthog drives by, beeping it's horn. Yes, tell Miss Keyes thankyou, but at the moment there is a Ghost coming up behind you about to blow you up... Quickly jump into the driver's seat before the Marines suffer too much damage, and kill off the pair of Ghosts chasing them. By default, you should have a Marine with a BR in the dreaded passenger seat, but I find BR's innefective. SMG's seem to do a lot more damage... Hmmm... If you can get a Marine with an SMG or more powerful weapon to get in, do so, but don't waste time. You're little brother wants a go by now! Tell him later, and drive down the slope and over to the Pelican to pick off some Jackals and harvest some ammo. If you prefer Ghost's to Warthogs, then take it by all means. Yes Marine, that's nice, but I hate the beach. Drive over the slope and gun your Hog forwards to ram a sniper. This part has a lot of Grunts and Elites. Kill them all, them drive past the large containers, pick off the Gunner Grunt in the Plasma Cannon, and continue to the next bit. Isn't this fun? Drive past the squad to your right and take out the Ghost that has just been mounted by an Elite. When you've killed some Covie's a Phantom will show up, and drop off a pair of Ghosts. More will rush over from your destination. Kill off the Ghosts while dodging Phantom-Fire, and eventually it should fly off and the place should be peaceful. A nice place for a picnic. Wait that Elite up on the tower! Jump out of your Hog and climb the ladder to melee attack an Elite to death. Jump straight off into your Hog and follow the Phantom to the next part. Drive your Hog for a bit, killing off a couple of Ghosts, but then you should ditch it to climb the nearby bunker. Grab your first Rocket Launcher in the game (yay!) and blow off 2 of the Phantom's Plasma Guns. It will retreat. Grab your sniper again and headshot the Jackal hiding up in the sniper tower. Now a rain of Elite Drop Pods will fall down. Some near your position, others on the other side of the field. Snipe 'em dead, but be wary that when they are doing the "getting out" animation they are invincible. Don't try it. It should be noted that an infinite amount of Ghosts will constantly appear from the rat infested tunnels, so get in there as soon as possible. Grab a Ghost, and the rest of the level is pretty straightforward from that point on. One word of advice: When you come across the Shadows, aim for the cockpit. It will do more damage. At the last battle you can just completely skip it and break for freedom, but that ain't any fun. As the screen fades to a celestial white, well done. You have completed Outskirts. My fingers are hurting. By Digi7 (If you liked say in the discussion section!)

Speed Run Walkthrough
Note: This walkthrough require correct Grenade Jumping, precision in everything and... speed. This walkthrough is based on the current fastest Speed Run at High Speed Halo, Fully_Synthetic and Chad's 4:43 Legendary Co-Op run, with a bit of minor editing as I personally deem fit to allow for Single-Player use. It may be altered as and when faster runs emerge. Certain portions detailed here may only take place on Legendary and alternate methods, not detailed here, will be necessary in such events.

Start moving towards the doorway. Jump onto the lamp in front, then onto the awning to the left. Turn back towards the hole you jumped up from and jump towards the pathway there. Throw a Frag Grenade as you fall and immediately jump again as you land so that you make use of the grenade's force in a Grenade Jump. Jump across the chasm to the building opposite. Throw a Frag Grenade at the wall of the building as you reach the top of the small slope and turn towards the building to the left, jumping as you reach the edge. Follow the path and jump down to the next area, then jump onto the pointed roof, then over the parapet. Follow the path in a straight line over to the next building, jumping as necessary. Throw a Frag Grenade shortly before you reach the small parapet and jump as you hit the parapet, letting the grenade blow you onto the next building. Continue walking in a straight line until you see the sign for Hotel Zanzibar. Jump over the gap between the building you are currently on and the next one, then head for the hotel and drop down. Go in and throw your currently last Frag Grenade at the Covenant in the hall, then hide to the left. Rush out and charge past the survivors, heading down to the beach. If you've been going fast enough, you should hear Miranda say "Sergeant, I need you on that bird" as you near a parked van. Find the crashed Pelican and the Ghost near it, then board it. "A Day At The Beach" will appear as you do so, as will a checkpoint.

Boost the Ghost past all resistance and head into the highway tunnel. You will get a checkpoint as you near the first turn. Once "Speed Zone Ahead" appears, get out of the Ghost and commandeer the Warthog that appears. Charge past the resistance. You will get a checkpoint as you pass the first group of Covenant, then a second near the little ramp.

Weapons Caches

 * The first one is on the second story of the main structure in the first plaza. Get on the second story and check under the stairs.It contains BR and Sniper ammo, a Magnum, and (interestingly) two SMGs that have a total of 430 rounds (80 rounds more than usual).
 * Another on is found after you encounter the Hunters. Go through the doors and go to you reach the two crates stacked on top of each other. Jump on top and turn right. You should see some bodies. Go towards them and you should see the ammo.There will be two dead Grunts and two dead Marines. There will be three Frag grenades, two fully loaded PPs, and a Sniper Rifle and two clips, plus one Magnum.
 * Another is very close to the above cache. When up by the bodies you should see a broken street light. Jump between it and the wall to get the ammo.
 * If you go to the building with the two Jackals on the bottom floor there are several Sniper Rifle clips as well as the gun.
 * A Sniper rifle cache is found in a balcony. It contains four or five boxes of ammo and a sniper rifle. This balcony also has the IWHBYD Skull when you trigger the events on Legendary.
 * The last one is in the third beach area, in the open area building. If you park on the right side there is a ramp that leads up to the top floor. Here is the only Rocket Launcher in this level, plus a sniper rifle, BR ammo, and Sniper ammo. On the bottom floor is two Rocket ammo boxes.

Legendary Walkthrough

 * For the first part of the level, when you are in the boxed-in area, take out your Battle Rifle and shoot all visible enemies. Once they are dead, take out your SMG and pick up a Plasma Pistol. Then, head for the building in the center. Charge the Plasma Pistol and when the Elite jumps down from above, quickly shoot him with the Plasma Burst and finish him off with a barrage of SMG fire. Take out the Grunts with the SMG, drop the Plasma Pistol, head to where the dead Marine is at the top of the stairs, get ammo then hide inside the building. You need to hide because for the parts that follow, Jackal Snipers will appear. In Legendary, they always get headshots, which take you out in one hit. Just pick up a Plasma Pistol every now and then, blast Elites with it, then shoot them. Use your SMG to take out Grunts or if you're a good shot, use your Battle Rifle to get headshots on Jackals and Grunts. Sometimes, the Covenant soldiers will try and get inside the building. DON'T LET THEM! Now, about the Snipers. Let JOhnson keep his Sniper Rifle. Since he can't die, he can simply eliminate the Snipers easily. But, if you see a Sniper and they don't see you, quickly headshot them with the Battle Rifle. Stay inside the building for the Drone part, take out only visible enemies. When the Hunters come, either let Johnson shoot them or, if you're brave, get to the turret and shoot them yourself. Whenever a Hunter begins to charge up a beam, shooting the Hunter will stop it from charging up the attack. When they are dead, go to the next part. Quickly headshot all visible Jackals with the Battle Rifle and avoid the Sniper that protects them. When all the Jackals are dead, do not proceed! The Famed "Sniper Alley" is murderous on Legendary. Instead, head back to the area where you killed the first patrolling Grunt and use the tactics you would use to get the Blind Skull(don't pick up the Blind Skull though). Jump from building to building on the side parralel to where the Hunters came from. Make your way to a yellow building where you have a clear view of the part of the destroyed bridge the Pelican was facing. Jump onto it and walk around until you see what looks like a giant ramp of debri below the bridge. Jump onto the ramp and walk up. This should bring you to Hotel Zanzibar. While on top of the ramp, take out your Battle Rifle and pick off the Ultra Elite and Grunts. When they're dead, jump down and head into the hotel. Be sure to grab a Plasma Pistol for the next part. Only head halfway through the building, then, when you see plasma fire, turn and head back. Wait for the Elites to come through then charge up the Plasma Pistol and quickly switch to Battle Rifle and kill the Elite that has no shields. Do this twice to take out both Elites. Duck behind something to recharge your shields if you have to. Kill the Grunts with an SMG and move forward. For the following part, quickly kill the Grunts around the corner, take out your Battle Rifle and hide behind a concrete block. Wait for the Phantom to drop off Covenant soldiers then quietly, take out the Elites and Grunts that arrived. Don't bother leaving your position when the Warthog arrives, because it's Legendary, the Warthog will usually only last a few seconds before exploding into flames. Just jump up to the second level of your current position then jump again to a small chunk of another destroyed bridge. This allows you to avoid a fatal encounter with three Ghosts. When the coast is clear, jump down and run to the downed Pelican. There's likely a few Covenant soldiers waiting for you so run in from an angle that's facing the nose of the ship. Jump up top and duck unless you have a death wish. This part requires skill and luck. In order to stop the gunfire, try and plant a grenade on the Elite. I did this and since all the Jackals were circled around the Elite, it blew them all to the sky. If you're not as fortunate as me, take out your Battle Rifle and kill the survivors. When all of them are dead, grab the Ghost that hopefully wasn't destroyed and head for the next part. I tried many different things to defeat this part but in the end, an all-out assault on the Covenant soldiers was the best way to go. Start behind the large, purple gun. Kill all the enemies in sight. Be sure to kill the Jackal Sniper first because, as I said before, they ALWAYS get headshots. When that porton of this part is clear, quickly take out the Ghost by driving behind it and firing like crazy. Then, get out of the Ghost and grab the Beam Rifle the first Sniper dropped. Use it to take out the second Jackal Sniper in the floating tower. Use the Beam Rifle to kill all the other enemies then get in the Ghost again, pick up the other Beam Rifle and head for the next part. Before you head out into the open again, get out of the Ghost and pick off all the enemies that are at the first pillar/tower structure. Also, take out any Covenant soldier who try to reach the parked Ghost on the far side. When all the enemies are gone, run to the first tower and climb 3/4 of the way up. Do this because there will be a Phantom coming that can shoot you when you're up top and 2-4 Ghosts that will shoot you when you're on the ground. Wait until the Phantom leaves then climb up and shoot at the Ghosts. Try to hit the circular power cells on the side, it destroys the Ghosts in one hit. When they're dead, make your way to the parked Ghost from before and head to the next part. Once you pass over the ramp thing, three Ghosts should attack. Use the same tactic for taking out the Ghost before, getting behind them and unleashing hell. When they're dead, park your Ghost behind the building in front of you. Run to the top, grab the Rocket Launcher and blow up 2 of the Phantom's guns. This will make it leave. By now, 3-4 Elites hve landed nearby. Grab the Sniper Rifle and take them out. If an Elite grabs your Ghost, blow him up since you won't need the Ghost anymore. More Ghosts will evntually come. Take the Sniper Rifle and use the same tactics as before. When they're dead, take out the Sniper on the far side in the floating tower then jump down and pick up a Beam Rifle. Walk to the other end until you hear a "whoose". These are the Elites landing in pods. Turn around and take a sniping position out of their view. Pick them off along with any other Ghosts that may appear then head into the tunnel. Bring a full Beam Rifle with you. Grab the Ghost at the entrance and head off. Every now and then, get out of the Ghost and kill all the Covenant enemies ahead of you. A WArthog will come to assaist you so take out anything that could destroy it since the Warthog will make very quick work of your enemies.Finally, when you reach the convoy of Covenant vehicles(I forget what they're called). Speed up to right behind the first one, this will put you out of harm's way. Shoot at it until it explodes. Continue this for the next three. Finally, for the last part, head onto the ledgey thing above and beside the road. Fire off a few shots with a Ghost. This will get the attention of the 3 other Ghosts. When they become visible, speed away. The Ghosts should follow. Just when they are about to shoot, turn a hard left and speed in the opposite dircetion until you come behind the slowest Ghost. Blow it up and follow the other Ghosts, blowing them up from behind. When they're all dead, speed into the opening area of the tunnel but stay behind something the whole time. There are three turrets, two Grunts controlled Plasma Turrets and an Elite in the turret of one of the Covenant vehicles from before. Kill all the Elites and Grunts that are running around then get out of the Ghost and shoot the Grunt controlled turrets with your weapons. For the last turret, get in the Ghost and destroy it with a barrage of fire. When it blows up, speed forward until the cinema scene begins. Seems easy, right?
