Dirty Pair: Project Eden

Dirty Pair: Project Eden is a side-scrolling action game based on the Dirty Pair animated series. Players begin as Kei, using her laser gun and jumping abilities to reach an enemy lair on a planet affected by civil war.

After Yuri joins on a flying bike, Kei can ride through the stage if she reaches it quickly enough. Colliding with walls or obstacles forces her to continue on foot. Reaching the destination shifts the game into room-based exploration, where Kei searches for items such as floppy disks and unlocks doors.

The game also includes simultaneous two-player action featuring Kei and Yuri. It was released for the Family Computer Disk System on March 28, 1987, and is known for its considerable difficulty.
