Stargate SG-1: The Alliance

Stargate SG-1: The Alliance, (or SG:TA for short), was a first person shooter based on Season 8 of Stargate SG-1. The game used a modified version of the Unreal Engine.

Overview
The game was said to have been based upon the events of the SG-1 seasons; the player was able to select their character for a mission and fulfil the roles of that character as seen in the TV show.

It was confirmed that the Alliance part of the name referred to the Alliance between Anubis and the new enemy, Haaken. The Haaken have never appeared in the TV show, they are a new alien race that was created by the developer's concept artists and game designers.

Cancellation
According to IGN.Com, an "administrator posting in the game's official forum stating that the game has been cancelled". However, this has never been officially confirmed by the developer, Perception Studios, despite forcing the majority of it's staff into redundancy in January 2006.

Gameplay
The game was a First-person shooter with an option for a third person perspective, consisting of objectives to be reached during various missions and levels. Since the developers have not shown much of the gameplay, it's not very clear how exactly the game was meant to play out. However, from the video from the "Stargate Atlantis: Rising" DVD, it appears to follow the storyline well.
