You are a human on an alien planet, there are Aliens green creatures, Ice Alien's light blue colors aliens, the MOM, the mother of all aliens, and the son the little shit colored alien. You have to try to fight them all off with your weapons. There is also a nest that can only be destroyed by granades.

Use arrow keys to move around. CTRL to throw grenade at aliens, move the mouse to aim, and press the mouse to fire. M will toggle the music on and off. P to pause the game. There are several weapons availble: machinegun, shotgun and the very powerful grenaded. As you will kill enemy aliens sometimes they will drop health packs for you. Good luck in this Alien Showdown!
