Plot
In the game, the player controls A.D.A.M., a battle android, as he fights his way up a tower with eight floors, the first seven named after the seven deadly sins. It offers a sad, twisted, love story instead of androids gaining their "self".

Trivia

 * Rengoku 2: The Stairway To Heaven is actually based from the poem/story The Divine Comedy by Dante Alighieri.
