This post is for anyone that might be visiting the site, but isn't familiar with Supreme Commander. Supreme Commander (aka "SupCom") is a real-time strategy simulation by Gas Powered Games, and essentially the sequel to Total Annihilation. Whatever TA started, SupCom continues, with massive maps, easy-to-use gameplay, and great multiplayer.
If you're thinking this might be a game up your alley, check out the demo. Worth Playing has a copy of it available here. The map is called Finn's Revenge, and you can only play as Cybran. Even still, it's enough to wet most gamers appetites for more. If you're looking for more info on how to play the map itself, check out our forums and the subforum for Finn's Revenge.
