Unlock Levels
The cheats these other fools have submitted are obviously garbage and made up. You can unlock the foundation MP map by finishing campaign mode on easy. there are also two other maps to unlock: Marathon and Conclusion. Try finishing harder campaign modes to unlock these levels.

Play as Miranda
This works in campaign, as well as multiplayer. On any map, find a turret, use it, and turn it three times to the left. After that, get to the final boss for the level, and press Start, Up, A, A. Next level you will play as Miranda. The confirmation noise will be a girl orgasming.
