Build absurd contraptions, launch wooden ragdolls, and trigger chaotic chain reactions inside a mysterious testing facility. Switch between first-person building and free-cam mayhem. Complete challenges, unlock gadgets, and discover hidden areas.

You are wondering around deep inside the RMF Ragdoll Testing Facility: a sprawling, half-forgotten testing site filled with malfunctioning gadgets, leftover mannequins, and decades of questionable experiments.

Guided (and occasionally insulted) by the disembodied voice of the Facility, your job is unclear. There's no staff. No signs of life. Just doors that still open, machines that still work, and a growing sense that whatever this place was built for... it's still running.

Nobody’s watching. Probably.
