Those who ordered Guitar Hero 5 in September and took advantage of the free Guitar Hero: Van Halen offer are starting to get their game in the mail, offering a peek at something that's flown under the radar until now.

The game arrives in a promotion-copy-only sleeve, with the same advisory stamped on the disc so, no case and no full value for those who think they might flip it for cash or store credit. Recipients also found no evidence of the means to export Van Halen tracks into Guitar Hero 5, probably another resale-defeating mechanism. although who knows if this capability may be enabled once the game is fully on sale in the U.S. Dec. 22.

On the whole, the game appears to be based on Guitar Hero: Metallica, skinned for Van Halen. More pics and details at the link.
