Supreme Commander: Forged Alliance is an all-new standalone add-on for THQ's Supreme Commander. The title will function as a complete game in its own right, but will also bring a variety of extra features to the first game.

Supreme Commander fans can look forward to an all-new campaign, a host of innovative multiplayer features, more maps, an entirely new faction and over 100 new units (fully realised navies, orbital weaponry and advanced counter intelligence tech).

"Supreme Commander: Forged Alliance is not only the continuation of the epic story that is unfolding inside the game's universe, it is the continuation of our goal to move the bar for RTS gaming even higher than ever," said Supreme Commander creator Chris Taylor.

Supreme Commander: Forged Alliance is scheduled for release on PC in November.
