In a top-secret laboratory, a group of genetically modified lab rats has developed advanced intelligence but are still stuck in their cages. Players will take on the role of Rex, the bravest and most cunning rat, as he leads his fellow rodents through a series of daring challenges to outwit the mad scientists and police dogs guarding the lab. Along the way, players will solve puzzles, make alliances with other animals, and experience humorous dialogue and dramatic encounters. Every choice impacts the outcome, leading to multiple possible endings based on your decisions and teamwork.
