The player may roam about on foot or by horse to complete missions as a man named Buck Crosshaw across two game maps, Arizona (with deserts and mesas) and Oregon (featuring forests and mountains).

An in-game store and currency system allow for upgradable clothing items, weapons, and horses, with optional microtransactions available for additional or premium credits.

As missions are completed, the player is rewarded with coins and experience points, unlocking access to higher tier items from the store.

The main storyline and campaign follows Crosshaw's discoveries of the happenings and fate of his lost wife, while a multiplayer mode features online team deathmatches and capture-the-flag.

Buck Crosshaw, a lone, and amnesiac outlaw, awakens in the Arizona desert and heads west in search for the nearest settlement.

The Exorcist explains that the outlaw gang is a secretive cult fixated on performing a ritual to summon demonic and supernatural entities into the world, including the devil himself.

Buck emerges from the mine and buries the Exorcist’s body, vowing to rid the land of the remaining demonic entities.
