Monsters, Inc. on the PlayStation 2 is a 3D platformer based on the Pixar film.
Players control James P. "Sulley" Sullivan through 8 levels based on environments from the movie, including the scream factory, the streets of Monstropolis, Sulley's apartment, the Himalayas, and more. In each level, the main goals might include picking up one or more special items, or simply finding the exit. Sulley has to make his way across platforms, ladders and conveyor belts by jumping, climbing, flipping switches and pushing crates around. Enemies are rare, but Sulley can take them out with a whack of his tail, which is also used to break crates that contain items. There are also stealth sections, where Sulley has to avoid being seen by another character. Since the game is intended for younger players, there is no limit to the retries to any level, and helpful hints are always available.
Each level also includes a number of collectibles and special tasks. There are 100 discarded screams to pick up - finding a certain percentage of them unlocks mini-game bonus levels. There are also 5 scream canisters to find and a small challenge involving scaring 5 mice within a time limit. If both are completed, clips from the movie are unlocked.
Developer Kodiak Interactive closed down in December 2001, while the game was in beta. It is not precisely known who took the game to completion: no other studio besides Kodiak is credited in-game, but Monsters, Inc. Scare Island developer A2M's logo is displayed on the packaging.
