Cuphead

Cuphead is a 2017 run and gun game developed and published independently by Studio MDHR. The game follows its titular cup-head character and his brother Mugman, as they make a deal with the Devil to pay casino losses by repossessing the souls of runaway debtors. In the game, up to two players control Cuphead or Mugman to fight through several levels and boss fights; the game does not have a rigid narrative structure. As the game progresses, the protagonist acquires more power and abilities, eventually facing the Devil. Players, however, can only equip a limited number of these abilities at a given time.
