Supreme Commander: Forged Alliance cost to play

Supreme Commander: Forged Alliance came out in November 2007 as a standalone expansion to Supreme Commander, the large-scale strategy game from Chris Taylor's Gas Powered Games. Nineteen years later it still has a steady audience on Steam: over the 30 days to 20 October 2026 it peaked at 1,210 players online at once. Online play now runs through Forged Alliance Forever, a community-run client, which our guide explains.

Players

Steam Charts shows a steady audience rather than a dying one. The monthly average has stayed between about 640 and 790 players for more than a year:

Month	Average players	Peak players
August 2025	727	1,390
October 2025	666	1,320
December 2025	706	1,367
January 2026	790	1,579
March 2026	766	1,526
May 2026	743	1,379
July 2026	713	1,348
September 2026	639	1,233
Last 30 days to 20 Oct 2026	614	1,210

The all-time Steam peak is 2,072, in October 2022. Steam Charts' records for the game start in July 2012, when the monthly peak was 314.

Forged Alliance Forever runs as its own program on top of an installed copy of the game. FAF doesn't publish player numbers on any page we could read, so we can't say how many of its players Steam counts. Copies from GOG or old CDs aren't counted by Steam.

How it plays

Supreme Commander: Forged Alliance is a real-time strategy game and a standalone expansion to Supreme Commander. You build bases and command armies on land, at sea and in the air, on what Square Enix calls an epic scale, with full navies, orbital weapons and counter-intelligence technology.

The new single-player campaign is set two years after the Infinite War. A new enemy, backed by the zealots of The Order, threatens to wipe out humanity, and the three human factions, the UEF, the Aeon Loyalists and the Cybran, have to put aside old hatreds and fight together. That enemy is also a new faction you can play in multiplayer, described as masters of quantum technology.

The expansion adds 110 new land, sea, air, base and experimental units, along with new multiplayer maps. Steam lists single-player and multiplayer modes.

What it costs

Forged Alliance costs £8.99 on Steam UK. The original Supreme Commander is also £8.99, and the Gold Edition, with both games, is £14.99. There are no in-game purchases. Forged Alliance Forever is free, but you need to own Forged Alliance to use it.

For comparison, Age of Empires II: Definitive Edition costs £25.99 before its expansions, and Command & Conquer: Generals – Zero Hour comes in a £19.88 collection.
