EA has released a Brutal Legend demo on Xbox Live Marketplace.
Update: As you rightly pointed out, this is only available to people in the US and Canada.
It's massive at 2GB, but offers a long-awaited taste of Tim Schafer's latest creation, in which roadie Eddie Riggs travels to a fantasy, heavy metal-themed land. The full game arrives on 16th October. Our extensive coverage can be found below.
Also, Activision has popped an XBL sampler for Wolfenstein out. This is considerably smaller at 578MB and not nearly as exciting. That's because the supernatural Nazi-themed shooter has already been released and reviewed. Our Wolfenstein verdict can be found elsewhere.
