Gameplay
Munch's Oddysee was the first game in the Oddworld series to be in 3D, unlike the 2D Abe's Oddysee and Abe's Exoddus.
Abe's chant possession ability was also changed. In Munch's Oddysee it appears as a small ball of energy which the player controls. In order to possess an enemy, you need spooceshrubs, which are green and ball-shaped. They can also be used for opening some locked doors. Other new features include Abe's ability to pick up objects and people, and different vending machine power-ups, such as Expresso, which increases speed for a limited time.
The most significant new feature is the ability to switch between Abe and Munch. Munch has his own abilities, such as using his sonar to control the Snoozers from the control panel, as well as pick up grabbers. He can also swim in water, while Abe can not. In the Munch's Oddysee booklet, it warns that Abe can only possess Industrialists, but in gameplay, you can possess all the same creatures as you could in Oddworld: Abe's Exoddus, and for the first time, you can possess Slogs, though the options for controlling non-Industrialists are very limited. There isn't a proper use for possessing non-Industrial creatures apart from using them to fight each other; however, the possessed creatures are usually the ones killed.
