# Veteran mode
Reach Level 32 to unlock Veteran mode, which is a Co-op mode with much tougher enemies.
# Ray Gun in "Little Resistance" mission
After the boat crashes, call in an air strike on the specified location. Run up to the beach, and move to the right. You will find a small puddle at the right side of the beach. Stand in it briefly, then move towards the middle of the beach to find a smaller puddle. Stand in that puddle briefly. Move towards the far left side of the beach. Stand briefly in the puddle in the barb wire. After several seconds, the screen will shake, and you will hear strange voices. Four lion statues will rise out of the ground with alien Ray Guns in their mouths. -From: Chris Hauserman

# Extra ammunition
Use the following trick if run out or are running low on ammunition on any mission in Solo mode on any difficulty. Find a non-essential teammate (someone not involved in the story line). Walk up to him, and aim the reticule next to his head or torso. Knife the air, and as you do so move slightly towards them so that the reticule is over them. If done correctly, he should die and drop his weapon. Non-essential teammates will get replaced when you walk into a battle. If the teammate does not die but keeps getting back up, they are essential to the story (for example, Sgt. Roebuck and Sgt. Rezenov).
(There are glitches in the game, but I don't feel like posting them for this game.)
Reach Level 32 to unlock Veteran mode, which is a Co-op mode with much tougher enemies.
