Martians have invaded the Earth and enslaved our animals, but worst of all, they made Lazergoat angry. Now, he wants revenge! Inspired by classic arcade shooters like 'Galaga' and '1942', LAZERGOAT: INVASION is a difficult, never-ending battle against hordes of alien enhanced animals, from the streets of Earth to the canyons of Mars. Lazergoat's only objective is to kill as many of the creatures and Martians as he can before he dies. And he will die. Often.
