In an interview which was published the day after the announcement of the game, Experiment 101's head of studio Stefan Ljungqvist said that the game already was content complete. He also mentioned that one of the most difficult things for the development team was to balance the combat system in order to "combine shooting, melee [attacks], and abilities in a quite intuitive way".[4] Unreal Engine 4 is being used for the game's development.[9]
