Paranautical Activity: Deluxe Atonement Edition -Action with a first-person view that uses mechanics taken by developers from the Rogue-Like genre. The gamer has to pick up a virtual protege of many different firearms that will help to fight off enemies and destroy entire waves for their own survival. The single -user regime contains 45 awards of varying degrees of difficulty unlocking. Subject to all of them, the player may claim to complete all available content.

The gameplay of this indie project is as dynamic as possible due to the active protagonist who knows how to quickly run, jump, and striphy. The gameplay is as aggressive and wild as in the Quake and Doom series. The features of these franchises added randomization and hardcore of the pants like The Binding of Isaac, which gave rise to a rather interesting mixture with more than hundred levels and hidden stages. They can be met by 40 types of enemy creatures that will attack the protagonist as soon as they see. Also, there are battles with bosses that take place under a clockwork soundtrack in the Dubstep genre, like all other shootings.
