Gex 3: Deep Cover Gecko

Gex 3: Deep Cover Gecko is a 1999 platform game developed by Crystal Dynamics and published by Eidos Interactive for the PlayStation. It is part of the Gex video game series, and was released in 1999, followed by ports for the Nintendo 64. Its protagonist, Gex, is a wisecracking, pop culture enthusiast voiced by Danny John-Jules in the UK and European releases and comedian Dana Gould, reprising his role from former Gex games, for the American release. The gameplay is set in Gex's secret hideout, Mission Control a overworld, which is overseen by Gex's butler, Alfred the Turtle. Playboy model Marliece Andrada plays Gex's kidnapped companion, Agent Xtra, the only live-action character, who is featured in brief full-motion video sequences on the PlayStation version. The plot follows Gex's return to the Media Dimension to rescue Agent Xtra from Rez, Gex's arch-nemesis from the previous games.

Gex 3 was conceived as a sequel to 1998's Gex: Enter the Gecko and incorporated unused elements of the game's design into Gex 3. Advancements in the utilization of available technology allowed Gex 3 to feature a set of bigger levels, more on-screen characters, different textures, and a retooled camera system over its predecessors that maximizes gameplay improvements with consideration to the hardware limitations of the time. Certain aspects from the original Gex were brought back as well, such as the addition of secret levels and bug collectibles. A 2D game titled Gex 3: Deep Pocket Gecko was released for the Game Boy Color in late 1999 which used the same plot and themes as Deep Cover Gecko.
