Defend your planet against the alien invaders in this new version of the classic arcade game. Either shoot black or white bullets to take down each invader. After each wave you will then need to take out the UFO ship flying at you. Be careful because the UFO can change colors. Try to complete each mission given to you in order to unlock all of the achievements.
How to play: Touch left and right or use arrow keys to shoot black or white bullets.
