Gex

Gex is a side-scrolling platform game developed by Crystal Dynamics and originally released for the 3DO in 1995. Versions of the game were later released for the PlayStation, the Sega Saturn and Microsoft Windows. It was a pack-in game for Panasonic models of the 3DO later in the console's life.^[1][2]

It is the first game in the Gex series and introduces players to the title character, a wisecracking gecko, voiced in this game by comedian Dana Gould. Gex served as Crystal Dynamics's mascot, and was intended as a competitor to rival the likes of popular video game mascots such as Mario and Sonic the Hedgehog.
