Take out the bad guys in this fast-paced shooter! Take on a first-person vantage point and navigate the halls of a massive building. Bad guys and monsters wait at every turn, so be sure to keep your gun ready. Use your arrow keys to move your character around and use your space bar to fire your gun. Be sure to keep an eye on your ammo at the bottom of the screen. If you run out of ammo, you're out of luck! Your health and armor toolbars will show you how much damage you've taken and how strong your armor is. Avoid getting shot or hit by bad guys to keep these numbers up.
