If you own Guitar Hero: Metallica and want to buy Guitar Hero: Warriors of Rock, it would be smart to grab that game within a week of its September 28th release. Activision's offering a nice incentive to do so.

If you buy Warriors of Rock between September 28th and October 5th, you'll be able to import tracks from GH: Metallica for free. The full list of disc import tracks from GH: Metallica are below.

Note that the promotion is only being offered to PS3 and Xbox 360 owners in the US. The import will otherwise cost 480 Microsoft Points/$5.99/600 Wii Points.
