Game Starsiege: Tribes
Starsiege: Tribes (commonly referred to simply as Tribes) is a sci-fi first-person shooter video game. It is the first of the Tribes video game series and follows the story from Earthsiege and Starsiege. It was developed by Dynamix and published by the company now known as Sierra Entertainment in 1998.
Tribes was one of the first online-only games of its kind and sported several multiplayer features that other games have only recently included (32+ player support, 128 players max, troop transport vehicles, several different player classes). Most of the standard maps were outdoors in a variety of climates, from sunshine to snow and hail. In general, bases were scattered throughout the map depending on the gametype. The outdoor environments were and still are relatively huge, extending for several kilometers in any direction, but “jetting” and “skiing” gave Tribes a fast-paced feel.
