It starts off showing the pillar of autumn after Halo: Reach, where the ship and its crew discover Installation 04 or “Alpha Halo”. It then goes to Cortana and Captain Jacob Keyes where they talk about the Fall of Reach and the pursuing Covenant Fleet of Particular Justice lead by Supreme Commander Thel’Vadamee. Soon the Fleet catches up and Keyes puts the ship on full alert. It then goes to the hangar bay, which has Pelicans flying around, Warthogs on the move and Marines getting to their positions. Sergeant Major Avery Johnson then gives a speech to his Platoon before they run off to their positions on the ship, preparing for boarders. Cortana then gives the message to Sam to open the hatch to the Master Chief’s Cryo-tube. Nathan then goes down. First, Nathan will tell you to look around. Once that’s done you must exit the Tube. Now Nathan will tell you to run around the Cryo Chamber until you know how to walk and run. Then you will stand in this box and look at set lights. Now, just walk into the Shield Recharger. Your Shields will now activate. Then Nathan will tell you to activate the vaporizer. A Plasma Pistol Overload will destroy your shields and let Nathan see if they recharge. They do. Nathan will then go onto teaching you about Weapons but Keyes interrupts him. He says that the Chief is needed at the Bridge. Nathan will argue, but Keyes wins. Cortana then mentions that Covenant Boarders have been reported through out the ship. An Elite Major Domo will then blast the door down and kill Sam. He will try to kill you but, fails and runs off. Nathan will then tell you to follow him. You follow him. Seconds later a blast rips through the bulkhead and kills Nathan. Go back. Then jump over the pipes and go to the left where you will see 2 doors. Go through the one that’s straight ahead. Another explosion will come through, avoid it. Go through the door. Go to your right and you will see crewmen with pistols will come under attack from Elites. Crouch under the door and go straight ahead. Then more Elites and Grunts will come from ahead. Go through the door to the right. Go through the other door. An Elite Minor will be be waiting behind the door and is about to go berserk but he gets hit by Assault Rifle fire and retreats to the left while firing his Plasma Rifle. Go to your right and two marines with Assault Rifles will be standing there and firing at the Elite. Ignore them and go your left. Two more crewmen with pistols and a marine will be spotted behind a barricade. They will be firing at Grunts and Elites [remember you are unarmed so you should not bother fighting]. The marine will come up to you and tell you to follow him. You will go through the mess hall where wounded marines will be found. And out through a door, two more crewmen behind a barricade will be found fighting more Grunts and Elites. Just go to your right. Keep going until you see a blue arrow on the ground saying “Bridge”. Go through this door. Go to your right and then left and you’re on the bridge. Just go talk to Captain Keyes. After the cutscene he will give you a pistol you may then exit the bridge. Then follow the path up to the crewmen behind the barricade. As soon as you see the arrow, the pistol will become usable. Kill the Grunt Major and the 2 Minors that are standing there waiting. You may pick up their weapons. Then go through the door that’s straight ahead and into the mess hall where a squad of marines are. You will automatically pick up an Assault Rifle.

MISSION COMPLETE!!!!
- Before you enter the bridge, there is a picture of earth and billboards saying "Fight for her!" etc. But on The Maw, none of these can be seen
- There is a Glitch where you can walk through a Escape Pod Hatch and walk around the Autumn. But you can't go far for you meet a Barrier
- On the bridge, once keyes gives you a pistol shoot him in the head and you'll kill him. Cortana will call for reinforcements to kill you. Johnson and a group of marines will try to kill you, they are invincible.
- Doing the Hatch glitch, you will see that the Plasma Torpedoes coming from the "CCS-Class Battlecruisers" are actually spawning out of nowhere. This due to Bungie not knowing of the gltich in the Level
