You must defend your tower at all cost from the animals using various weapons

The more animals you kill the better weapons you will get, but the animals will also get better units as they send more. Your goal is to send a nuclear-strike to get rid of the animals for good, if you play in two-player mode the second players goal is to destroy the tower so the animals can get peace. Use weapons ranging from cannon to deadly ray-gun and fight everything from the harmless sheep to the monstrous DNA experiments.

Features:

* Defend your tower with a large arsenal of weapons
* Let either a friend or AI send the animals
* Unlock the 8 mini-games and fight for the highscores
* Survive long enough to send a nuclear-strike
