It looks like it won't be long before the public will get a chance to play a portion of Space Siege, the long awaited sci-fi action-RPG from developer Gas Powered Games and publisher Sega. A banner and a countdown clock on NVIDIA's NZone gaming site indicates they will debut the demo which seems to indicate a release late on Sunday or early on Monday.

The game, which has your player character fighting off nasty aliens on a ship that carries the last members of the human race, is scheduled to ship to stores late in August. There's no word at the moment on what the demo will contain at this point.
