Quartet

A platform game hybrid from Sega for one to four players, who can choose between Joe (yellow), Mary (red), Lee (blue) and Edgar (green). The action takes place in a series of side-scrolling levels, most of which consist of simple platform action. However, some levels require players to collect jetpacks and the focus of the game changes to a standard side-scrolling shoot-em-up. The aim of the game is to destroy an army of robots that have taken over an Earth colony satellite station. In each level there is a boss that must be destroyed. When he dies, he releases a door key that you can use to exit the level. Weapon and character power-ups can be collected to help players with their task. Due to its potential for four-player shoot-em-up games, Quartet's gameplay is somewhat similar to the Atari classic "Gauntlet" from 1985 (although it's nowhere near as well done).
