Become a Cat Agent of the Underground
In an underground city unseen by humans, animals have formed their own agency to protect creatures living in the human world. To return to the surface, the protagonist must complete training, earn a pass, and take on their very first mission.
But as missing cats, a mysterious factory, cat allergy medicine research, and a hidden conspiracy within the underground city begin to surface, the protagonist realizes this mission is far more than a simple investigation.
Jump, Sneak, Solve Puzzles, and Push Through Danger
Play as a nimble kitten traveling between the human world and the underground city, using a cat’s natural agility to complete all kinds of missions.
More Than Platforming: Special Mission Stages Await
Memorize targets, recreate sequences, and uncover hidden clues.
Hold tight to a minecart and carve a path through the tracks of the underground world.
Discover the hidden entrance, step into the secret room, and find a little surprise reserved for the most observant agents.
Watch for warning signals, seize the right moment, and deflect incoming projectiles back the way they came to clear wave after wave of turret threats.
Adjust your height, time your throw carefully, and use darts to destroy both fixed and moving targets in a special agent shooting-range challenge.
