Exterminauts is a cooperative third-person PvE shooter developed by Behaviour Interactive and published by Level Infinite. Set on the scarred alien world of Tian, players assume the role of Exterminauts—hardened interstellar professionals tasked with eliminating alien threats, repairing critical infrastructure, and responding to crises across hostile industrial worksites. The game emphasizes blue-collar aesthetics and gritty sci-fi worldbuilding, blending corporate contract work with survival against unpredictable alien encounters.

The core gameplay loop centers on squad-based missions where teams deploy from an orbiting depot into hazardous environments, complete high-pressure objectives under time constraints, and extract before alien encounters spiral out of control. Successful mission completion yields resources to upgrade equipment and evolve tools, preparing crews for increasingly challenging contracts. The game supports up to three-player squads, with teamwork and tactical coordination essential to survival.

Combat employs a distinctive weaponized power-tool system inspired by blue-collar equipment, including specialized firearms such as the Ice Gun, Electric Gun, Anti-Gravity Gun, and Foam Gun. Players execute dynamic combat actions including sliding, zipline traversal, rolling, and powerful Overclock abilities. The alien ecosystem features diverse creatures with unique mechanics and weaknesses, set against environments where nature, machinery, and extraterrestrial life collide in a colorful yet dangerous landscape.

Exterminauts differentiates itself through its working-class thematic focus and objective-driven gameplay structure that emphasizes base defense and infrastructure maintenance alongside pest elimination. The game blends squad-based shooting mechanics with resource management and progression systems, drawing comparisons to titles like Deep Rock Galactic while maintaining its own identity through blue-collar narrative framing and specialized tool-based combat.

The title targets cooperative multiplayer enthusiasts seeking challenging PvE experiences with emphasis on teamwork, strategic planning, and replayability. Its mature tone, featuring unrealistic alien gore and blue-collar language, appeals to players aged 18+ seeking grounded sci-fi action without the typical military shooter aesthetic.
