What the fuzz is that?!!!!
The premise of the game is a space ship is invaded by these alien creatures (which reproduce at alarming rates) the the crew must fight to eliminate the aliens before they take over the ship and kill the crew. One person plays the alien creatures, which evolve from eggs (completely harmless) to adults(killing machines), and either one or many people play the ship crew. The ship crew can move about from room to room and pick up items (ranging from grenade like objects, to tools, and fire extinguishers) which will help them to fight off the aliens.
Each crew member and alien form has a defensive, offensive, and movement rating which affects what they can do and how effective they do it.
How's that for an explanation in a nutshell?
