Calabasas (CA) - THQ has said that it’s working on a follow-up to the real-time strategy game Supreme Commander that was released earlier this year.

In a quick turnaround, THQ will bring out Supreme Commander : Forged Alliance in November, just nine months after the original title was released in the US, reports Eurogamer.net.

Supreme Commander hit the PC game sales charts at #4 the month it debuted, and remained in the top 10 in March.

Forged Alliance, which will act as both a standalone game and an expansion pack for owners of the original, will add 100 new units to the war simulation arena.

The original game, developed by Gas Powered Games, still retails for around $50. The expansion has not yet been given a price.
