Zap… zap… zappity zap zap! That’s the noise u will hear as u zap the alien invaders into oblivion! How many waves of these insidious creatures can u withstand? WELL?

Tis a shooterer-upperer game. U need to click or press the aliens to death. If u do not, they will invade ur world and kill all the men and keep ur women for slaves. That cannot be. U are all that stands in the way of doom or victory. Which will it be?

Watch out for powerups, they may come in handy.
