Supreme Commander: Forged Alliance is the stand-alone expansion to Gas Powered Game's Supreme Commander released early this year. The story picks up right after the events of Supreme Commander with an intro movie highlighting the events of the past couple of years; the Seraphim (the game's new faction) enter the universe through a quantum rift on Earth and launch an all out campaign against mankind. The three factions from the previous game are forced into an alliance as a last hope to fight off the Seraphim.
The game includes a campaign consisting of 6 missions; playable by each of the 3 original factions. The early missions are more enjoyable than in the original due to the fact that you have access to the entire tech tree from the start (minus some of the new units which you gain access to throughout the campaign), whereas in the original you were stuck at Tier 1 or 2 for most of the campaign. This does have the downside though that you spend the beginning of each mission teching up since you often donâ€™t start with a base. All of the missions play out relatively similar consisting of you gating to the planet and setting up defenses to hold of the constant AI attacks, which provide a negligent threat once you build up sufficient defenses; teching up to Tier 3; and then proceeding to destroy everything on the map. There are a couple optional secondary goals in each of the missions which vary based on which faction you're playing as and provide a small amount of variety to the campaign missions.
With access to all of the tech tiers you are immediately thrown in to huge battles. The scale of Supreme Commander just doesn't compare with any other RTSs; with 81x81km maps that can take ground units 5-10 minutes to move across. These missions let you explore the full power of your arsenal in epic land sea and air battles that are larger than in the original game.
Supreme Commander's technical requirements are fairly high due to the massive amount of stuff going on in the game but the game runs very smoothly except for the occasional 10 second freeze I would get about every half hour, and looks great on a system that can handle the requirements. Forged Alliance brings with it improved graphics via higher poly counts, improved shaders and textures. Also improved is the game's UI, which saw an overhaul, making it more useful.
Supreme Commander: Forged Alliance is a welcome standalone expansion which adds a large set of features to the already great Supreme Commander.
