Well not really. It's called body invader. I've got it at http://www.typhoonent.com/body invader.swf It's a work in progress. If anyone has an idea how to fix the problem of the wrong one disappearing I'd like to hear it. How this game works is you click on the ball things and then you're virus will shoot at them. You're the black thing. If you want to target another one than you need to push delete. The keys 1,2, and 3 gives your virus different battling tactics.

I've played sheep invaders before.

I like the game, I guess.
