Category: Main Games Allegiance


Allegiance is based on an original concept by Gene Ball & Rick Rashid.  Members of Microsoft’s Allegiance / Zone team have gone on to work on games such as Halo, Dead Space, inFamous, Sid Meier’s Civilization, Microsoft Flight Simulator, Crimson Skies, & Grand Theft Auto.

- Allegiance was originally developed by Microsoft and released March 2000. The game received great reviews, but was too far ahead of its time (before high speed internet). Still the unique, highly strategic game-play allowed Allegiance to maintain a loyal following. In 2004, Microsoft released the source code to Allegiance. In 2017 the game's license was changed to MIT.

- If you would like to contribute to developing Allegiance, all the source code for the game, and website are  hosted on GitHub at and

- Staff are online via IRC at

Allegiance is a free, online, multi-player space simulation game. You pilot spacecraft, flying in a team with other players, defending and attacking sectors in space. Allegiance challenges your tactical ingenuity, your ability to function in a team and your prowess at blowing stuff up. Experienced players take command and lead their teams to victory or defeat.
