This is your fight-forward on the ship. Your aim is to find the Captain, who is trapped in a prison cell above you. It's a long drawn out fight. You being in a big room. Wait until you kill everybody, and then you'll be guided to going through a door and hitting a dead end. Now go out and around to fight your way up to the other side of the door, so you can let your buddies through.

You fight around to the second floor and then up to the third floor, where you reach the prison room. The captain gets out of his cell and starts talking about the Halo control room, and how it's really important to find it.
