Gex 3: Deep Cover Gecko (1999)

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.
