I just jumped on my Xbox 360 and surprisingly a new demo was up, and this time it was the long since out in stores Perfect Dark: Zero.
The demo is on the Xbox Live Marketplace, and weighs in at 860MB. I had to delete a few other demos to download it, as I did not have enough space on my hard drive for it, but now that its downloaded I can tell you that it has one level that you can play in solo or co-op, and one multiplayer map called Plaza.
It seems like an alright demo release, but I am not really liking Perfect Dark.
