Heat.net was an online PC gaming system prouced by SegaSoft, Sega's PC game division. Heat.net hosted both Sega-published first- and second-party games, as well as popular third-party games of the era, such as Quake II or Baldur's Gate. Heat.net was based on a licensed version of the MPlayer Internet multiplayer gaming system, which itself later became GameSpy. The "currency" in the gaming system was "degrees", earned through playing games, game-related or general trivia contests, viewing ads, or other actions (like hosting enough game rooms in a time period). Heat.net had a loyalty program, in which members, known as "Foot Soldiers", received shirts and Heat.net dogtags.
