Gex 3: Deep Cover Gecko is a platform game for PlayStation featuring Gex, a humorous gecko. Players navigate through levels that satirize multiple television genres while working to rescue Agent Xtra from the antagonist Rez. The game incorporates TV sets as entry points to various areas, with remote control collectibles essential for advancement in the Media Dimension.
When Gex is watching TV one day, he discovers that Rez has kidnapped Agent Xtra (the agent from Gex: Enter the Gecko's backstory), head of the TV Terrorist Defense Unit, to get to him. He teleports to the batcave-like lair he has in the Media Dimension, and begins another adventure. Each level parodies a certain aspect of television culture (here the levels exist as stand-alone channels). Gex enters each level through a television set. He must collect remote controls to advance to the next level in order to complete his mission and rescue Xtra.
