Cyber Lip

Cyber-Lip is a 1-2 player side-scrolling game where you must fight your way through several areas, and defeat a boss at the end of each one. Along the way, you can pick up a variety of weapons along the way, and use them against the invaders. By destroying certain enemies, you receive a "core bot", which is a ring that surrounds you, and when this touches the invaders, they are destroyed. Time is against you. When it expires, you lose a life.
