Description
Players control either Joe (yellow), Mary (red), Lee (blue) or Edgar (green) across a number of sideways-scrolling levels. The object of the game is to advance through the level, fighting opponents that come out of portals in the walls, and eventually defeat a boss that carries the door key used to open the "exit door" for the level.
How to Play
Players can find various power-ups during play, such as a jet pack that allowed characters to stay airborne, springs to jump higher, speed boots, and point bonuses. Each character has a separate characteristic weapon type, which can be upgraded by picking up a coloured bouncing orb that bounced across the screen occasionally. Picking up the orb when it is a player's colour gives a weapon power up, while picking up the orb when it is another player's color gives a point bonus (but deprives the other player the chance to upgrade).
