Supreme Commander : Forged Alliance

This is an expansion of Supreme Commander, but is a stand-alone as well, which will offer some genuine improvements.

You will now fight aliens, better known under the name Seraphim, with great gameplay, graphics, UI and audio, so you have the best circumstances to get into battles and win the war.

Though there’s a multiplayer mode, the solo mode is still pretty good; you will have to discover the torments of strategy on a level that will require patience and experience.
