Serial Cleaner is a story-driven, fast-paced stealth/action game, characterized by a 1970s theme and aesthetics. The protagonist is a professional cleaner, which means he takes care of cleaning up murder scenes by disposing bodies, covering up blood stains and hiding murder weapons and other incriminating evidence. He takes on jobs without asking questions, working shady assignments for the mafia, as well as taking on jobs from mysterious clients, which will put him in harm's way... more so than what he's comfortable with.
