In it, you play as Louis, and the objectivefor each level is to get to the exit (A red door)

The red bar is your HP and the yellow bar is your ammo, and each time you reload, you lose a clip.

Red power-ups are HP refill's, and yellow power-ups are ammo refills.

After you're done using your main gun, and you don't have any more ammo, you switch to your pistol, and youhave to click to shoot instead of holding the button down.

Controls:
WASD - Move
Left mouse button - Shoot
R - Reload

Our clan password is lolwut. Don't ask, TeeKay came up with it. We'll use it whenever we make a clan game, like when the outpost gets attacked.
