Dude Theft Wars is an open-world sandbox game set in a satirical urban environment. Gameplay centers on free exploration, completing various missions, and interacting with the world using touchscreen controls for movement, driving, and combat. The sandbox design encourages chaotic experimentation with the physics and numerous vehicles, items, and characters.

The mobile version offers a substantial single-player experience focused on causing mischief, undertaking story-driven tasks, and unlocking new areas. Players can engage in activities ranging from mundane jobs to elaborate heists using an inventory and weapon wheel adapted for touch interfaces. The world operates with systemic, often unpredictable, AI behavior.
