This (along with City) are my earliest memories of the Gizmondo, or at the time as it was known the Gametrac.

Promising silky smooth visuals, it was way ahead of the competition at the time, but yet being listed on the official website at the time, it was only later found out that Fathammer decided to drop developed of the game for some unknown reason and the hopes of a fps on the Gizmondo all but died (well until homebrew hit the Giz!)

Game blub;

SGS - SpeedGun Stadium sets the player in the middle of a violent futuristic TV-sport. Armed with a force field and a firearm, the contestants must battle each other in different mazes and arenas, referred to as Stadiums, in ferocious competitions for highest kill counts.

The SGS competitions, hosted by Bill Sunday, are constantly watched in millions of homes as the favorite TV show since Who Wants to be a Millionaire. Bill, the announcer, comments on game events while the cheers of the audience are played through the speakers in the Stadiums. Success in SGS will bring the contestant the cheering of millions of fans, while falling from their favor dooms the player into a torrent of hisses and boos. The strong presence of the audience in the game is one of the elements which differentiate SGS from the run-of-the-mill FPS games.

SGS matches are played in three rounds of three minutes each, and they are occasionally interrupted by Match Events: shouts from the audience influence Bill to spice up the game by (for instance) making special weapons available, disabling player force fields or letting loose hunter/killer robots.

At heart, SGS is a futuristic first-person shooter much in the visual style and feeling of Unreal Tournament. The hero's only mission is to eliminate the enemies infesting the arena. To aid the character in this mission there are different weapons to be found in the Stadiums.
