Shape-shifting aliens have taken over the city! Fortunately for us, a trio of
heroes called the Alien Buster have agreed to wipe out the attacking alien
force. This Alien Busters team consists of the following members: a muscular
man, an athletic woman, and a robot. Since each side-scrolling stage is filled
with attacking aliens, you must punch, kick, and blast your way though them in
order to advance.
