Color Ball Defender is a simple defense game.

Shoot the incoming attackers either in 2D or 3D mode.

Guard your color balls and don't let the attackers come too close. If the attackers cross the red circle, your color balls will die.

Try to survive as many waves as you can! You will be rewarded with a double gun in wave 5 and a triple gun in wave 10. And for a more relaxed shooting fun, you get the auto aim power-up in wave 1 and a new one in every tenth wave.
