Gex is a series of video games starring its titular character, a talking gecko named Gex. Gex's passion for TV makes him a target for the series' villain, Rez, who wants to overthrow the Media Dimension. Crystal Dynamics also used Gex as their mascot for several years.

The games are largely inspired by American TV culture and Gex makes wisecracks that serve as media and pop-culture references.

The series has sold over fifteen million copies combined on every platform the games were released on. In the series, Gex 3: Deep Cover Gecko is the best selling of the games. It sold over six million copies and became the best-selling adventure game on the PlayStation in 1999.


There have been three strategy guides released, one for each respective game. A "How to Draw Gex and the Gang" book was also released as was a "Gex 3: Deep Cover Gecko Novelization" book.



Gex is the star of the series. He spends most of his days watching TV when not having to stop Rez.


Rez is an evil robot bent on taking over the Media Dimension.
