If you can't wait to get your alien shooting rampage started with Space Siege (coming August 22nd for the PC) you'll be happy to hear that a demo was released today. The demo is about 930MB's and can be found on Nvidia' s Nzone, and some other fine websites. 

Space Siege was made by Gas Powered Games, and designed by game-guy Chris Taylor. If you don't know him, he is an ex-Canadian veteran of the gaming industry, probably best known these days for determining the design parameters behind Supreme Commander and Dungeon Siege.

Space Siege does not look particularly ground breaking or original, but that does not mean it might not be fun. The game is pretty easy to describe: picture Diablo or Dungeon Siege, make the dungeon a interstellar space-ship and swap the bows and arrows with guns, the monsters with aliens, and there you go. Top-down, overhead view (like an old early nineties arcade shooter), light RPG elements, upgradable and swappable gear and armor, hordes of creatures to shoot, a couple of branching plot points, and you have a reliable (if unoriginal) game dynamic.

In addition to the demo, a video was released today, featuring gameplay excerpts and Chris Taylor giving some insightful commentary -- such as this part at the 4:08  marker: "Blowing up stuff is kinda ah; kinda ah big part of the game...blow up a lot of stuff...and move out of the way here -- clever about, the way I shoot stuff," he says.
