Stargate SG-1: The Alliance is a cancelled FPS based on the Stargate TV series. The project was never released, but a playable PC version was found by The Gaming Liberty and they started to share as much as they can from this lost game. This version seems almost finished and as we can read from their preview, it could have been a great game especially for Stargate fans. Thanks to Denis from The Gaming Liberty for the contribution!
