Dash Text: This is Colonel Rodgers of the United Earth Federation. I need you to come in and clean up the mess left by those Cybran Chipheads and Illuminate fanatics! I’m ordering you to download the playable demo of SUPREME COMMANDER 2 and experience the award-winning real-time strategy game yourself. Fight the enemy on air, land, and sea, in spectacular environments on different planets. SUPREME COMMANDER 2 has everything you demand in an RTS: over-the-top experimental units, in-depth strategy, fast action, 4-player multiplayer, revolutionary controls, and more. There is only one true real-time strategy game, soldier, and that game is SUPREME COMMANDER 2. Download it today. Colonel Rodgers out.

The FIFA demo pits Italy and Spain against one another and has a new, optional, two-button control scheme to make the game more accessible for new comers. Presumably this applies for our American friends who may get a touch of the “soccer” fever come June.

Which demos have you downloaded? Let us know below.
