Your goal in this fun game that will require quick wits and multi-tasking skill is to build, maintain, and upgrade Defensive Sentries while shooting on enemies' forces. Use "WSAD" KEYS to move, Use YOUR MOUSE to aim and shot. Press SHIFT to toggle Settle Mode on/off. Press SPACEBAR to disrupt time (Causing slow-motion all over the map). Use 1, 2, 3 KEYS to switch weapons (Vulcan/Cannon/Spread). Good luck!
