The Scheme (ザ・スキーム, Za Sukiimu) is an action-adventure game best described as the bastard child of Castlevania II and Metroid. The game is set up into separate levels, and within each level is a boss and a gate, both hidden somewhere in the level. The gate will only open once you have collected the item to open it from the boss, but as the game progresses you will quickly learn that finding either one at any moment in time is a very daunting task.
