You're not alone. Every player is a different baboon, part of the failed Subject series.

You start with nothing — and die often. But with every run, you get smarter, faster, weirder.

Customize your baboon, evolve abilities, form factions… or betray them.

Failed experiments roam these halls, each more twisted than the last.

Every encounter teaches you something new about survival.

Learn their patterns, exploit their weaknesses, or become one of them.

Evolution doesn't always go as planned in the lab.

These creatures were once like you, now they're something else entirely.

Will you follow the same path, or forge your own destiny?

The final stage of the experiment gone wrong.

A grotesque fusion of flesh and fury that stalks the deepest corridors.

Face your fears, or become another failed subject in the endless cycle.
