Supreme Commander: Forged Alliance, is a standalone real-time strategy computer game expansion developed by Gas Powered Games and published by THQ, and the second title in the Supreme Commander franchise. Because it is a standalone expansion, it will be possible to play without owning Supreme Commander. Along with the new faction, called the Seraphim, Forged Alliance will add new gameplay features to the game, and will be further optimized for increase performance, in response to issues with the original. In multiplayer, playing as the three original factions requires Supreme Commander.
