Gas Powered Games' Supreme Commander 2 has been squashed into a demo and made available on Xbox Live.
The file's 586MB and can be queued for download on the Xbox.com site now.
What's in the demo is unclear. Colonel Rodgers - the game character who wrote the demo description, obviously - appears more interested in sounding off about the full game than listing specifics.
That full game, incidentally, is an RTS where lots and lots of little units blow each other up in the air or on land or in the sea. New to this sequel are chaotic experimental units and a more user-friendly approach.
