game by Scott Cairns and Alex Wallbank. David Anthony and Aldo Sampaio at Perception developed a dynamic audio system that allowed the audio to cross fade between different score, dependant on what was happening in the game. Perception were given access to all of the sound effects from the television series. According to Viljar Sommerback, the game had just passed the alpha stage of development and the game was "playable most of the way" but there were however "a lot of polish and bug fixing left to be done". The PC version was furthest along in development, followed by the Xbox version, whilst the PS2 was slightly behind that, with Lenzo commenting "The Unreal Engine was difficult to work with on the PS2. James Steele, our PS2 Lead, is still ripping his hair out about". Perception knew that they would miss their initial September 2005 finish date and before their dispute with JoWood had expected to move the release to February 2006. Planned release, promotion and cancelation The game was originally slated for release in late 2005 and would have been released on the Xbox, PlayStation 2 and PC. The first preview of the game was given in the Stargate SG-1 season eight episode "Avatar", which was broadcast in August 2004. In the episode, Teal'c becomes trapped in a simulation, with Perception creating the graphics in the style of the video game to represent the simulation. Perception launched the games official website in November 2004, offering the first screenshots from the game. In December 2004 MGM offered the opportunity for fans to bid to have their likeness used as within the game. The first teaser trailer for the game was released on March 5, 2005. The game was first shown at E3 in May 2005, with attendees able to play a level from game in both the Namco and JoWood booths. Stargate SG-1 star Richard Dean Anderson appeared at the event in order to promote the game. The full trailer released was released at E3 and made available online days after the event. A featurette which included footage of the game and interviews with the Perception team was included on the Stargate SG-1 Season 8 Volume 43 DVD, first released in July 2005. In order to tie the video game into the show, the shows producers planned to either show or mention the encounter with the Haaken in an episode.
