The Single-player demo for Supreme Commander, the spiritual successor to 1997's hit RTS
Total Annihiliation, is now available for download.
If you never heard of this game, you need to keep up on your gaming news

. What's not to be intrigued about enormous maps with up to 500 units
per player, gigantic units and even bigger explosions

.
Here's a quote from the recent PC Gamer:
PC Gamer, on March 2007, p.023, said:
[...] SupCom goes like this: Your Armored Command Unit (ACU) dramatically teleports in, constructs a base, and raises a huge robot army to wage war over land, sea, and air. Your ACU is roughly equivalent to the king in chess--powerful and versatile, but also slow and vulnerable--and if you lose him, it's Game Over. That chess-like game element significantly changes the standard (and somewhat tired) RTS gameplay formula for the better by forcing you to defend a high-priority target, but it just scratches the surfcace of what SupCom has to offer. Oh, and when an ACU dies, he explodes like a nuke. You don't usually see that in chess.
