Play against the computer with up to 2 friends in a skirmish mode.

Pushing the RTS genre to new levels Supreme Commander introduced battles the size of which hadn't been seen before. SupCom (as it's often abreviated to) alowed players to have a unit cap of 750 (and there are mods to push this further). The game has many similarities to Starcraft, most importantly the ability to play to your own style of strategy. The coop in the game is basically skirmish missions against the computer. The maps though are less inspiring and just resemble arenas rather than realistic terrain. Also the AI is largely disappointing (although improved in the addon) and easily beaten on most settings. From experience the Balanced AI setting offers the most challenge to seasoned players.Supreme Commander is an excellent game though and would suit anyone looking for a new RTS to play.
