Disney-Pixar Monsters, Inc. is a platform game for PlayStation 2 where players control Sulley, and optionally Mike, to return Boo to her home in Monstropolis after Randall destroys her door. Players navigate through various environments, evading Randall and the Child Detection Agency while overcoming obstacles. Gameplay involves jumping, dodging enemies, using attacks, and collecting items across multiple levels.
Boo has returned to Monstropolis and it is your job as Sulley (or Sulley and Mike in the GBC version) to get her back home. However, to make things difficult, Randal has destroyed her door.
Avoid Randall and the CDA (Child Detection Agency) as well as other dangers as you try getting Boo home. This platform scroller will have you trying to find out where you have been as you make your way through multiple doorways, up and down ladders, and more. Pick up items along the way as you jump and dodge enemies, use your roar attack, push items, sneak, and more.
