Monsters, Inc. is a platforming video game made by Kodiak Interactive for the PlayStation 2. This game is more like the movie (location wise) than Monsters, Inc. Scare Island. There are 8 levels in the game and 5 additional mini games that can be unlocked by scaring all 5 monster mice, 5 canisters and 100 red tokens all of which are scattered throughout the levels. Each level has you either do jobs in order to proceed or collect items for other monsters (such as materials for Boo's costume).
- The Scarefloor (get Thaddeus' manual and keycard.)
- The Mailroom (Ride the mail train and get to Boo while avoiding the CDA.)
- Main Street (Traverse through the rooftops of Monstropolis while trying to find Boo and avoid the CDA helicopter.)
- Sulley's Apartment (Run through Sulley's apartment building and find materials for Boo's costume.)
- Garbage Disposal (Chase Boo through the garbage disposal and don't get tricked by the monsters that look like her!)
- Himalayas (Go through the Himalayas to get to the village.)
- Doorvault (Explore the giant library of all the closet doors and don't fall!)
- Showdown (Shut down the power supply by scaring the switches and save Boo from Mr. Waternoose.)
