Unreal 2: The Awakening Cheats - Xbox

Ranger: Zoom in
When playing as a Ranger in a multi-player or in single player game, press [L] to zoom with the sniper rifle. To zoom in even further, click the Right Analog-stick.

Tech: Easy turret disabling
When playing as the Tech online, switch to your grenade launcher and use your primary fire on an enemy turret to easily take it out. This also works on enemies, but not as well. Also, if there is a room with people crowded inside, use the secondary fire with your grenade launcher to gas them all. Fire about two shots in the room to take them out.

Telefragging
This can be done with any character as long as the person you are telefragging is on your own team. When you go up to revive someone, immediately after you revive them press [Crouch] to telefrag them. Note: You will lose points.

Restore vehicle turbo
Exit a vehicle that has used up its turbo, then re-enter it.

The Avalon 2: Hidden area
In two player mode, when you are on the elevator someone can fall out by looking down right next to the computer. There is a space that you can use to crawl out, then the other player can push you out while you are trying to walk out that way. This may take a few attempts. When you are down there, do not talk to the repair man or else you will have to restart. Also, do not enter where the man walks out from or you will not get out.
