Run and take cover behind the transparent shielding. Get out your [[Plasma Pistol]] and take out each Sentinel with a charged shot. Plasma weapons work very well against the Sentinels. A single direct hit from a charged shot will take one out. Run up and hit the switch on the right to open the door. ===Part 02: The Gun Pointed at the Head of the Universe=== This next battle is a nasty one. The Covenant will easily take out these Sentinels if you don't intercede, and you don't want that. You want them to kill each other off down to the last man, so toss a [[Fragmentation Grenade]] or two into the middle of the Covenant group as soon as you see them. This will be a very long throw, but you just got a checkpoint, so you can restart if your aim is off. Hopefully this will not only kill off most of the [[Grunt]]s, but also blow their weapons your way. After the initial [[Elite]] and Grunts, a second group consisting of an Elite and two [[Kig-yar|Jackal]]s will come out to fight. Try to work it so the Elites get killed before the Sentinels. You can fire off a few charged plasma bolts, but don't get too close. If you do, some of the Sentinels will turn their attention towards you. Once they do, you'll have to take them out quickly. Try not to let that happen. Once the Sentinels are killed, pick up a [[Needler]] if one got blasted your way and use it on any remaining Elites. Use charged shots from your Plasma Pistol if you don't have a Needler. Run right up to the Elites as you're sending them charged shots then switch to your Shotgun and blast them. Finish off the Jackals with more charged plasma shots. That's a lot of plasma to go through, so pick up another Plasma Pistol whenever you can. Pressing yourself up against either wall and crouching will provide cover, but not very much. So you'll have to do most of this battle without recharging. Once everything is dead, put your Shotgun in a very safe place and grab a Needler, Plasma Pistol, and all the grenades you can carry. Next comes another tough battle. Open the first door and move through. Immediately after opening the next big door that leads outside, retreat. A bunch of Grunts will come wandering in after you and you want to keep your distance. Take these guys out with charged plasma shots. Back up to the site of the previous battle to recharge. Keep blasting until the Grunts are dead. Now you have two Jackals and two Elites to deal with. Get as close as you dare then look for an open enemy. If it's an Elite, fire off a magazine of needles towards him. If it's a Jackal, fire off a charged plasma shot. Use the stationary shields if you're feeling courageous, but be careful of Jackals dropping them with charged shots. They do that sometimes. Remember; enemies cannot see you crouching behind a stationary shield even though you can see them so stealth is an option here. Go back and grab more needles and a fresh Plasma Pistol when you're running low. Repeat until you've taken out nearly the entire Covenant. That last bad guy or two can be annoying to finish off, so don't worry about it. Find a decent Plasma Pistol and grab your Shotgun. Run up one last time and send off a few charged plasma shots and a grenade or two. Whoever is left will probably run for cover so follow up with your Shotgun at close range, blasting Elites and bonking Jackals. Now you can relax. No more tough battles for a while. Don't scavenge around here yet. Toss your Shotgun in a memorable spot and grab a {{Pattern|Okarda'phaa|plasma rifle}}. Keep your old Plasma Pistol as well. Walk up the ramp and into the tower. At the end of the path are a health pack, a [[Pistol]], and a [[Sniper_Rifle#Halo:_Combat_Evolved_and_Halo:_Combat_Evolved_Anniversary|Sniper Rifle]]. Toss both your weapons and grab these goodies. Remember where this ammo stash is. You'll be flying back up here later. Head down to the site of the last battle. You should have a nice array of weapons by now. The Sniper Rifle doesn't have much ammo, so you'll want to save that for later. The Pistol and Shotgun are your two staples. Always keep these around. Since that's what you're facing next, grab a Needler but keep your Pistol. Move off to the right (assuming you're facing out towards the canyon) and peek over the edge. You'll see several Covenant patrolling down below. Burn through all the nearby needles to soften them up then pick up a Plasma Pistol and toss the Needler. Peek over the edge just far enough to fire off a charged plasma shot at an enemy then quickly switch to your Pistol and zoom in. If the shot hits, follow up with the Pistol. Keep doing this until either all the guys below you are dead or you run out of needles and Plasma Pistols. Grab your Pistol and Shotgun and locate your Sniper Rifle. Continually switch it out with one of your weapons to toss it down to the level below. Follow it down and put your Shotgun in the face of anybody who was giving you trouble before. Now you have a large amount of space to work with and can look down on the enemies below you. Needlers are once again very useful since you can rain needles on enemies who can't find any cover. And if the Covenant aren't paying attention, you can often drop {{Pattern|Anskum|plasma grenade}}s on them as well. Look off the left side first. There will be a couple of Elites and a Jackal here. You definitely want to take these guys out with needles and grenades if you can. Head back to the right when you're done and take a look at the Covenant down below. A couple of Elites, a Jackal, and a Grunt. Snipe the Grunt and Jackal with your Pistol or charged Plasma Pistol shots. Head down the path and get the attention of the Elites then run back up top and move around behind them. Peer over the edge and toss a grenade onto them or let loose with a magazine of needles. Go back up and retrieve your Shotgun and Sniper Rifle. If you want to plan ahead, you can toss your Sniper Rifle down to the walkway below so you don't have to go as far to retrieve it later. Or you can even take it with you, constantly switching it out with another one of your weapons. You should have already taken out these next guys from above, but if there's anyone left just use the chunks of debris as cover. Sneak up then run out and pump a few Shotgun shells into them. Moving along you'll see two Grunts at the other end of the upcoming tunnel. Zoom in and kill them. Move up to where they were standing and take out the Jackal nearby with a few shots to his vulnerable spots with your Pistol. Toss your Shotgun (remember where it is of course) and pick up the Needlers dropped by the two Grunts. Stay out of the range of the two Elites ahead and unload your Needler on them. A few magazines later they should be toast. Now you should go retrieve your Sniper Rifle. Pick it up; toss your Needler and head back down to the bottom floor of the pyramid. Part way down the last ramp you will get a checkpoint, so take a moment before you trigger it to make sure you're set. Run back to the ammo stash if you're running low on rounds for your Pistol or Shotgun. And if you want you can move your Shotgun to the top of the ramp to make it more accessible later. Once you're ready, move ahead. After the checkpoint, get your Sniper Rifle out and zoom in on the Banshee ahead of you. As you move past the piece of debris the next group of Covenant will appear. An Elite will come running out from behind the Banshee, so put a couple of sniper rounds through him when you see him. It is possible to kill the Elite with your Pistol on [[Legendary]], but it requires all rounds to hit him. Switch back to your Pistol and look for Grunts and Jackals to snipe at. The [[Zurdo-pattern Wraith|Wraith]] will start lobbing mortars soon, so move into the shelter of the tunnel once things get too hot. From the tunnel you can peek out both sides and snipe most of the Covenant in the area. Use your Pistol to clear out the Grunts and Jackals, and then switch to your Sniper Rifle for the Elites. Be patient here, as sniping the [[Gold Zealot Elite]] will save you a lot of grief. Kill the Zealot and waste as many Elites as possible. Once you've emptied your Sniper Rifle and gone through a few Pistol magazines, there should only be a few Elites left. Now it's time to put the smack down on that Wraith. You've probably noticed that [[M19 SSM Rocket Launcher|Rocket Launcher]] by now. Go toss your rifle and pick it up along with an extra magazine of rockets to top it off. Be careful not to grab the [[health pack]] unless you really need it. Put those rockets to good use. Move through the tunnel and target the Wraith. Wait until it stops moving then fire. Keep watching for a moment to confirm you actually hit it then duck back into the tunnel away from the mortar shells. Three rockets will finish it off, but I recommend only hitting it twice. Instead of that last rocket, empty a couple of magazines of Pistol ammo into the tank. You will be filling up on Pistol ammo soon, so this saves you a rocket. Once the Wraith is destroyed, you can go back and grab the extra magazine of rockets. If you didn't miss, you should now have a full rocket launcher. Retrieve your Shotgun and switch it out for your Rocket Launcher. Now we have to deal with the last few Elites. Make sure there are only Elites left. Snipe any remaining Jackals or Grunts. The Elites have all probably migrated to the side of the pyramid where the Wraith was and where you probably are now. If not, harass them until they're all on that side. Now quickly run into the tunnel and drop down on the far side. Run up to the left wall and turn right so you're facing the back of the canyon. Run along the wall and hope the Elites don't see you. Once you've run all the way to the ice flow, turn around and head to the other side of the pyramid. Run up behind the Banshee, hop in, and fly away from those Elites as fast as your anti-grav pods will carry you. Hover over them at a safe height and pound them into the dirt with your [[Fuel Rod Gun]]. Once you've bombed them all into submission, head back up to the top of the pyramid to grab more Pistol and Shotgun ammo. You should be carrying both of these weapons. Fly up to the top and gather some ammo. Now you can head towards the nav point. Fly in from above. As you approach you'll see the door open for an Elite and two Grunts. Aim for the Elite and nail him with the Fuel Rod Gun. Finish him off with the plasma guns, but be careful. You want his Plasma Rifle, so notice where it lands. If the Grunts haven't retreated, take them out with the plasma guns as well. Land and switch out your Pistol for that Plasma Rifle. If you can't find it, grab one or both of the Needlers. Follow the corridor along until you come to the pulse generator. Hop into the middle of the beam to destroy it then run immediately to the back of the room. That's right, the side away from the door. A whole mess of Sentinels will move into the room. Peek in and use your Plasma Rifle or Needler on them. Duck back to reload, as they can take out your shields quickly. Your Covenant weapon should take them out pretty easily. If you run out of ammo, just move around the outside of the room and leave. ===Part 03: Breaking Stuff to Look Tough=== Head back out to your Banshee. You have two groups of Covenant to worry about here, one from each side of the bridge. Most of these Grunts are carrying Fuel Rod Guns. Take these guys out with some Fuel Rods of your own. Use hit-and-run attacks until there are just a couple of guys left. Try not to hover or you'll be an easier target to hit. You want to have at least one of their plasma weapons land on the bridge when they die, so don't blow them away with Fuel Rods. Try running into them or hosing them down with plasma. If you take a lot of damage, fly back up and grab your old Banshee. It probably hasn't taken much of a beating. Once you've cleared off the bridge, land on it and switch out one of your weapons for any old Covenant weapon lying around. This is why you needed to make sure one landed here. Now fly back down to where you left your Rocket Launcher and pick it up, tossing your Covenant weapon by the wayside. Fly back up to the land bridge and get out. Now you have a full Pistol, full Shotgun, and possibly a full Rocket Launcher all here on the bridge with you. If you're feeling confident, don't bother moving the Rocket Launcher along with you. If you can't stand the thought of leaving a Rocket Launcher behind, move it into the tunnels with you. You know the routine. Keep switching it out with another weapon as you walk forward. The previously mentioned tactic doesn't work very well on Legendary. The Grunt with a Fuel Rod Gun is much more accurate, and the Elites can hose down your Banshee very quickly. What you need to do is, if you didn't take the Sniper Rifle from the tower earlier, go back and get it, then get the Banshee up onto one of those semicircular beams above the blast door, and snipe all the enemies. It's an extreme distance, but that's what the sniper is for. Target the Elites first (remember to aim for the head), then the Grunt with the Fuel Rod Gun, and if you have any ammo left, kill the Jackal. Once they are all dead, go back to where you got the sniper and get your other weapon back. Move ahead through the corridor and you'll get a checkpoint. Keep going into the room ahead and try to bonk the lone Grunt before he gets into the interior of the room. There are a lot of Covenant in here with you, and this battle can be a real pain. Fortunately you have a Rocket Launcher! Unload on these guys. After launching a rocket, switch to your other weapon (doesn't matter whether it's the Shotgun or Pistol) to finish off anyone damaged by the explosion. By this time, you're out of rockets there should be far fewer Covenant in the area. The remaining enemies can be handled as usual. Bust out all the windows and use them to sneak around. Snipe Grunts and Jackals with your Pistol. Use charged shots on annoying Jackals or Elites. Stick grenades to any Elites who can't see you. Once there are only Elites left, fill them full of needles or move in close and blast them with your Shotgun. Once the room is clear, find a good Plasma Pistol, keep your human Pistol, and drop your Shotgun in a safe spot. The ramp ahead leads down to an area with three Jackals. Use charged shots to take them out. One will probably retreat to the next room. Let him go for now. Head back to the site of the previous battle and fill up a Needler, dropping your Plasma Pistol. You can move your Shotgun along with you as well since you'll need it eventually. Move down the ramp and past the area where you just axed a couple of Jackals. The next group of Covenant will appear at the end of this corridor, but they won't show up until you've moved part of the way down. If one of those Jackals retreated here, take him out now with your Pistol. Now, move forward until the Covenant shows up. Back up and fill the hall with needles. Fire off a magazine on one side of the columns, move over, reload, and then fire off a magazine on the other side. This should take care of most of the Grunts and possibly the Elites. Once you've emptied the Needler, go back and switch it out for your Shotgun. Head back to the battle and snipe any leftover Grunts with your Pistol. The Elites can be taken out a number of ways. You can rush them with your Shotgun or you can peer around the columns and stick grenades to them. Either way works. Once they're dead, you can move into the next room where you will get a checkpoint. Stay up against the right wall and move to the base of the ramp into the next room. Stay out of sight while the battle rages on ahead. Once it dies down, move up to the top of the ramp, but not all the way into the room yet. Walk in just a step and look to your left. Over the little wall, you should see a couple of Elites that survived the battle. They will notice you and start shooting. While they're firing, take careful aim and stick a Plasma Grenade to one of them. If that doesn't take them all out, throw another grenade or just rush in with your Shotgun to finish the job. Several Jackals and a [[Zealot Elite]] will be coming around the corner soon, so back up. Stay at the top of the ramp until you see them. Toss a couple of Frag Grenades towards the Jackals and retreat down the ramp. From down here, you can take out the rest of them. Snipe the Jackals with your Pistol, and if the Elite Commander comes down after you, stand your ground and blast him with your Shotgun a few times at point blank range. Some of the Jackals may come down after you as well, but as long as you're on the right side of the doorway, they'll have to expose their unshielded side to you as they walk, which makes them fodder for your Shotgun. If the Commander hangs back, wait until the Jackals are killed, then rush him with the Shotgun or stick a grenade to him just like the previous Elites. To your right, there is a Shotgun full of ammo, several Frag Grenades and two health packs. Go fill up and look through the slits into the other side of the room. You don't really want to waste Pistol ammo on something this easy, so grab a Plasma Rifle or something. Peek through and hose down anybody you can see. Be careful of the window. You should probably stay crouched. Just keep firing until all the Grunts and Jackals are dead. Go back and grab another plasma weapon if you need to. Be patient and eventually, killing one of the last Grunts will trigger a group of Flood to rush in behind the Covenant. Once this happens, grab your Pistol back and get your Shotgun ready. These guys should take out the rest of the Covenant for you and should be easy for you to kill. Just move through the room and take them all down with your Shotgun. There will also be some carriers towards the back, so don't let them sneak up on you. Search carefully and you'll find some valuable Pistol ammo amongst the bodies. Be sure to grab it. And head back to grab a health pack and more Shotgun ammo if you need to. Moving along, you'll come to another battle between the Flood and Covenant, this time out on the bridge. Run out the door, take a right around the support, walk up behind a Jackal and blast him with your Shotgun. Blast another if you can. Retreat, get your Pistol out and snipe the rest of the Jackals. After the entire nearby Covenant are either dead or retreating, follow them down the bridge. Snipe any Flood that are lingering around on the other bridge, but not if they're also firing on Covenant. At some point the Zealot will come to kill you. Back up and blast him a few times with the Shotgun. He should go down pretty easily. Peek around one of the walls in the middle of the bridge and toss a Plasma Grenade onto an Elite. There should be several running around ahead. Keep sticking grenades to them until they retreat. Move ahead to their previous position and keep an eye out on the other bridge. Several Flood will jump over soon. Back up when you see them and hope they all go after the Covenant. Shotgun any who come after you. If there are any Jackals left, zoom in and snipe them before proceeding. While the Elites are still recovering from the Flood assault, rush in and spread buckshot liberally around the area. If the Covenant are all dead, so much the better. The rest of the bridge should be cake. Just keep your Shotgun at the ready and look out for Flood jumping over from the other bridge. The next room contains a huge amount of Flood, but is relatively easy. Run in and head straight into the interior of the room. Fire off a few Shotgun shells into the Flood at the other end of the room then retreat. When you reach the door you just came out of, turn around and toss a grenade at the oncoming wave of bad guys then keep on retreating into the hallway. Back up so the Flood have to come around a corner to get to you. As they come around blast each one with your Shotgun. Toss grenades as necessary and keep backing up if you get overwhelmed. There will inevitably be some stragglers, so move back up and use the same tactics until they've all been taken care of. There are still three groups of Flood to deal with in this room. One on the left, one in the middle, and one on the right. Let's take the one in the middle first, since they sometimes will interfere with your other fights. Move into the interior of the room and look up the ramp. These guys are armed with Shotguns and Pistols, so be careful. Snipe with your Pistol or move up the ramp and use your Shotgun. Grab all the ammo they dropped. Then, head back the way you came to the exterior of the room. Assuming you're facing the interior, we're now headed left. This group is at the far end of the room, almost at the door. Toss a Plasma Grenade right into the middle of them. They aren't that bright, so they should just stare at it until it goes off. Any survivors will probably come after you, so Shotgun them. Now it's back around the way you came only this time we're headed right. Walk up and just blow these next Flood away. They aren't that well armed. Standing in the doorway out of this area are two Elites, who are waiting for a fight. If it hasn't started already, move towards the doorway until it does. It should be a pretty fair fight until a Flood with a rocket launcher shows up at the far end of the corridor. Peek around far enough to watch the battle and snipe this guy as soon as possible. If you see him fire a rocket, retreat. Peek back around and make sure this guy goes down. Take out any survivors as usual. If you're a big fan of the rocket launcher, you can pick this one up for now, but it's not very useful. I usually just leave it. Cruising along you'll come into another room with a smattering of Flood. Kill them, and then move towards the interior of the room. Hiding in the first vent on the right is an infected human, so snipe him before he makes a nuisance of himself. There is also a Flood on the second ledge on the left. He moves between the interior and exterior of the room, so you may have to wait for him. Take him out with your pistol when he shows up. Move towards the center of the room and keep your shotgun trained on the second vent on the right. You will trigger an explosion. A few Flood will come out of the vent and a ton of infection forms will drop down. Quickly blast the combat forms then retreat before the little guys overcome you. Keep retreating and managing the little guys so they don't get through your shield. Once they're all popped, move back into the centre of the room, blasting anybody on the way. Once you're in the middle, the rest of the infection forms will suicide on you. There are a few Flood left in the exterior of the room near the exit. Most of them have pistols, so you can use up your pistol ammo on them. Once you've sniped all of them, move in to pick up their ammo. You can also grab the health pack lying by the door. There are a great amount infection Flood waiting in the hallway ahead, so take them all out before moving on. The next battle takes you back out onto the double bridge for the last time. There are two Banshees flying around in the air and a bunch of Flood on the bridge with you. Wait around in the hallway for a bit and the Banshees will take out most of the Flood for you. Once you're tired of waiting, run out and get the attention of the nearby Flood. Duck back into the hallway you came from and shotgun each of them as they come after you. That should clear out a bit of space on the bridge. Enough for you to take out the Banshees. Stay near cover and gun them down with your pistol. These guys will often fly in close, so blast them with your shotgun if you get a chance. After several dozen pistol rounds, they should be grounded for good. Move out onto the bridge now and switch to your shotgun. Several Flood will appear, but it's nothing you can't handle. Zoom in with your pistol and look down the length of the bridge. Snipe any Flood that wander into your crosshairs. A few have rocket launchers, so you want to take them out from as far away as possible. About three quarters of the way along the bridge, a big group of infection Flood will appear in front of you. Ditch one of your weapons, pick up anything handy, and blast these guys. If you can't find another weapon to use on these guys, just run around and keep recharging like you usually do. Grab your old weapon once you'r
