About this game

Become a Firefighter

Answer emergency calls and rush into dangerous situations together with up to 5 friends. Put out fires, break into collapsing houses, save civilians, and try to keep everything from turning into complete chaos. Every mission is a race against time, smoke, and your own bad decisions.

Do your job

You are not here just to make a mess with hoses and axes. The dispatcher expects results, which means responding to emergencies, completing objectives, and keeping the situation under control.

  • rescue civilians

  • handle false alarms

  • fight spreading fires

  • complete dangerous rescue missions

Fail too many calls, and your reputation will go down in flames.

Physics-Based Chaos

The entire game is built around physics-based gameplay and a destructible world. Walls collapse, debris falls, water impacts players and objects, and every emergency can spiral into complete chaos.

Stay alive

Firefighters are not invincible. Getting hit by debris, blasted by water pressure, run over by vehicles, or caught in the flames can put you out of action fast. Work together, rescue unconscious teammates, and adapt to the chaos around you. In a burning house, one mistake can bring the whole mission down.

The game heavily focuses on physics, destruction, and chaotic co-op teamwork.
