Take on MegaCorp contracts amid energy supremacy clashes, while aliens' thirst for Polymorphic Plasma disrupts plans. Punch In. Clean Up. Get Paid.

Forget the righteous battle cries of heroes. Here, combat is stripped down to a professional routine. Form a tight-knit trio of gritty, down-to-earth Exterminauts dealing with corporate honey traps and blood-soaked pest control. Every work order costs company money, so cover your crewmates, tally up your expenses, and survive your shift together.

Industrial-grade gunplay where your everyday tools are your firearms. Unleash a flood of firepower with heavy-duty utility and repair equipment repurposed for slaughter. Activate the multi-purpose OVERDRIVE system to turn typical blue-collar gear into devastating, alien-shredding weapons.

TIAN is a living world that fights back. You aren't just shooting bugs in an unchanging arena; you're invading a living, breathing ecosystem. With the alien threat always adapting to your squad's tactics, your 3-player team is forced to constantly communicate, reposition, and change strategies to survive this chaotic slugfest.

With every contract bringing new obstacles, players must adapt, work together and sharpen their skills to survive the next dirty job.

Developer Behaviour Interactive and publisher Level Infinite, in partnership with TEAM SHOOTER & CREATIVE, today announced that the Exterminauts Closed Beta begins November 12 on PC.

Players are invited to step into the boots of blue-collar galactic field technicians, tasked with tackling dangerous alien infestations in chaotic co-op gameplay across hostile off-world worksites. The test introduces a variety of weapons, tasks, alien pests and other surprises for the upcoming third-person PvE shooter. Players can sign up for a chance to join the crew and take on the challenges awaiting them on Tian. The Closed Beta runs from November 12 at 6:00 PM PT to November 18 at 6:00 PM PT.

We're looking forward to seeing how players tackle the job and make the experience their own."

“Exterminauts offers a distinctive take on cooperative shooters, putting players to work in a colorful sci-fi world where alien infestations and hazardous job sites turn every deployment into unpredictable battles ,” said Hakan Hu, Publishing Lead at TEAM SHOOTER & CREATIVE. “The Closed Beta is an opportunity for players to get a feel for the game's unique blend of teamwork, improvisation and off-world chaos, and we're excited to see crews take on the job together.”
