Supreme Commander, abbreviated as SupCom, is a real-time strategy computer game designed by Chris Taylor and developed by his company, Gas Powered Games. The game is considered to be the spiritual successor to Taylor's 1997 game, Total Annihilation. First announced in the August 2005 edition of PC Gamer magazine, the game was released on February 16, 2007 in Europe and February 20, 2007 in North America. A standalone expansion, Supreme Commander: Forged Alliance, was released on November 6 of the same year.

Supreme Commander is focused on using a giant bipedal mech called an Armoured Command Unit (or ACU) to build a base, then upgrading units to reach higher technology tiers, and conquering opponents. The player can command one of three nations: the Aeon Illuminate, the Cybran Nation, or the United Earth Federation. Supreme Commander was highly anticipated in pre-release previews, and was received well by critics, with a Metacritic average of 86 out of 100.
