In a dystopian future where humans have been turned into lab rats for experimental tests in a sinister underground facility, you play as a sentient rat named Professor Nibbles. Your mission is to outsmart your captors and become the ultimate experimenter. Navigate through a twisted maze of bizarre experiments, rival rats, and eccentric scientists while collecting bizarre items that grant you unique abilities. Engage in witty banter with other lab rats and decide whether to cooperate with them or backstab them for your gain. The game features branching paths, where your choices will dictate your rise to power - or your demise as a mere test subject.
