Dirty Pair: Project Eden is an action game based on the anime movie of the same name. The player can choose to play alone as blue-haired Yuri or with a friend in two-player mode, controlling red-haired Kei. The game has four sections.
The first two sections are auto-scrolling platform stages where you must jump and shoot enemies. In these stages, the environment is straightforward. However, in the last two sections, the environment changes to a maze layout with non-linear rooms. Your goal is to find disks to progress through each section. Some rooms are locked and require special items to unlock them.
