Passwords in Gex are seen by collecting VHS cassettes in certain stages, with cassettes being awarded automatically for defeating a boss - this is the same system used on the 3DO to allow the user to save, though here details on points and lives are lost in the process.

The most significant change lies in the saving system - on the 3DO, progress in Gex can be saved to the system's internal memory, and despite the Saturn and PlayStation (and PC) versions being more flexible in save game storage, this feature was omitted from these versions for unknown reasons, being replaced with a password system instead. Gex was built with the 3DO in mind, and was converted to the Saturn and PlayStation with minimal changes. Plans for a third sequel were put in place for the PlayStation 2 but were ultimately scrapped. The success of Gex lead to two 3D sequels, Gex: Enter the Gecko and Gex: Deep Cover Gecko, both of which skipped the Saturn.
