Eliminator (4 Players, prototype)

Eliminator is a multi-directional shooter in which players must use four buttons to take control of their ship: two to make them rotate left and right, and two more to make them fire and accelerate. Players pilot a space ship around the playfield and must destroy alien drones. The ultimate goal is to evade and destroy the Eliminator, a huge asteroid base. The players fire causes any enemy that is struck (with the exception of the Eliminator itself) to rebound and careen off in another direction.
