. "Move down the path until you find a small entryway into the vents. Proceed inside and search for a ladder in the floor. You'll see Infection Flood popping out of the hole. Spray them with the Rifle, then drop a grenade in the hatch to take down the Carrier below. Then follow the ladder down. You'll be greeted by Sentinel lasers. Drop them, then turn the corner, following the path until it appears to dead end. It isn't a dead end, though. Soon, a door will spring open and Flood will stream out. Fall back and waste them, then make your way through the door they burst open. Keep moving down the path, removing enemies and generally kicking ass until you reach a flaming mass to the right. Move through the green-lit door ahead. In the hallway that bisects it, you'll see a Hunter on either side. Use grenades and your Assault Rifle to take them down, making sure you don't go after one and leave your back open to the other. When both are dead, search the locker room in this hallway for Shotgun ammo, grenades and health packs. Then enter one of the two doors that lead into the cafeteria. There are a whole lot of baddies on the opposite side of this room. Elites. Armored Elites. Enemies who like to throw grenades. Always keep a path clear to retreat, because you'll have to fall back a lot to avoid grenade throws. Be very methodical and patient with this room. There's no reason to rush. Throw your own grenades, wait for good shots and pick off the Elite one by one. If you take a shield hit, fall back and regenerate. If you really get dinged, go back to the locker room and grab another health pack. When all of the Elite fall, move through the room to the far left corner. Blast the annoying Grunts with the green energy rifles, then fall back and let them explode. Move across the next hallway into a narrow maintenance passage. Here, you'll find another batch of Elite. Smite them with the mighty Shotgun and continue to the bridge area. Here, a cutscene will trigger. You have set the self-destruct sequence in motion, only to have the Monitor thwart your plans. Time to do it yourself... When the cutscene concludes, shoot down the Sentinels that appear. Or don't. Head back the way you came. There will be a door open that wasn't previously. Flood are waiting there to kill you. Teach them that's a bad idea. Smoke them then move through the room they came from... it's an armory. Head to the door at the end of the room and go through. There's a pair of big, bad Hunters off to the right. Move straight past them into the passage ahead, then move through a couple sets of doors to find some Sentinels and Flood battling. Move forward and finish them off, then duck under a half-closed door on the left side of the hall. More Sentinels wait in the passage ahead. Smoke them, then move through the door here. In the next hall, you'll see a yellow arrow on the floor pointing toward the Cryo Bay. Move into the room to find a group of Sentinels hosing down the Flood. Slay anything that moves, then head to the far end of the room and climb the ladder here. Take down the Sentinels in the glassed-in observatory deck above, then get ready for a slew of Flood from the left. Drop them as they attack, then move down this passage. The path will eventually dump into a long, gray hall. Stay there for a second and prepare for another Flood attack, this time from the door on the opposite side of the passage. Once you wipe out the Flood that charge, move forward into the area they vacated and grab the Overshield here. Return to the gray hall and move left, toward a bunch of toppled debris. Here, you'll find a door into the air vents. Go through. Follow the narrow passages until you reach a small, grated green door. In the destroyed area back here, you'll see plenty of corpses and plenty of grenades. Grab what you can, then head back into the vents. When you enter these tunnels again, take the first left into the hallway, then quickly duck back into the tunnel. There's tons of everything in the passage you just tiptoed into\u2014Sentinels, Elite, Flood, Hunter. The fight will rage on without you, so let it. There are several routes into the passage to the left in addition to the one you just used. Move to the opposite end to find a health pack and bundle of Frag grenades near a sealed-off door. Then move over one more and hang out near the edge of the corridor. If you look to the right, you'll see Hunters and Elite. If you look to the left, you'll see Sentinels and Flood. Take down the Elite and Hunter if you wish, otherwise, just torque into the hallway, take a right and leave all of the nonsense behind. While it's fun to contribute to this fight, it has nothing to do with you. Follow the path until you see the path to Engineering. Then follow the path forward until you reach a crossroads."@en .
