5mintokill is a truly addictive online shooter. The name speaks for itself: you have 5 minutes to decimate all players or get decimated. You spawn in a random map point. No weapon, no ammo — nothing. You must run around all the buildings faster than your enemies and find some armor and guns. Once you acquire the stuff, move on to eliminate hostiles! The last is the winner!
Controls: WASD for moving, LMB for shooting, RMB for picking up.
