Gex was a platformer game series, developed by Crystal Dynamics, that details the adventures of a gecko named Gex. In this page you can see a couple of concept arts from the cancelled Gex 4, a cancelled project that was probably in development for the PS2. The series followed Gex the gecko. A lazy, tv crazy young man who after inhering a large fortune from his late uncle purchases the largest tv in the world.
Upon eating a fly which was actually a metallic transmitter, he is pulled into the digital world by his soon to be arch nemesis RezWhile. Not much is known about this sequel in terms of plot or overall any information. The last media ever released in the Gex franchise was a book in 2000.
