Codemasters have released an Overlord II demo on the Xbox Live Marketplace, which is available in all Xbox Live regions.
Download this action-packed demo of Overlord II and experience the thrill of sending your Minions off on a hilarious destructive rampage. Use your horde of Minions and new wolf mounts to slay the hunters of Nordberg! There's more: take on hippy elves and the mythical yeti and, err, lots of baby seals.
