1. Cheats - by holding down start and pressing either x, o, square, and triangle, you can activate god, all weapons, level warp, and full map.

2. Auto-run - by default your marine will now run without having to hold down the run button. When you do hold down the run button, you will walk.

3. Map zoom - pressing up or down on the dpad/nub allows you to zoom in and out in the automap.

4 Gamma - by default the current gamma setting is 3, instead of 0. This brightens the game consideratly, however, may cause some washout.
