A procedurally generated nightmare
You are a rat trapped in the sinister facilities and controlled by an evil AI. Every day, horrific experiments are carried out in deadly mazes. The maze is procedurally generated, ensuring that no two parts are the same. You must complete the objectives—find the cheese, avoid traps, and outwit the Cyborg Hunters—to survive.

Upgrade and escape fate
Death is inevitable and part of the experience. However, you can improve and evolve your rats to give them the necessary advantage against the AI. Unlock new experimental and twisted rat types, like cyborg or mutant rats. Every rat counts and every death is part of you and your companions' desperate attempt to escape this sinister place.
