Your mission in this fast-paced strategy game is to defend your human colonies against the aliens. Create ships and earn experience to defeat the attacking forces. Every few seconds the action will pause, and you will have the chance to place additional ship to help defend your reactor. Use YOUR MOUSE to aim and shoot. Protect the reactor at all costs! The game will end when it is destroyed. However, every game played will reward you with experience points, which you can use to upgrade your ships and buy new ship designs. Good luck!
