Activision is offering folks across the US an unheard of limited time bonus offer, which could also be interpreted as a sneaky ploy to lure gamers away from Rock Band: Beatles which is to be released, also during September.

With every purchase of specially marked copies of Guitar Hero 5 during the month of September, players will be able to get their hands on an advance copy of the unreleased Guitar Hero Van Halen long before its planned release in December for free.

What?! Yeah you heard read correctly. Buy Guitar Hero 5 and get GH: Van Halen before its planned release for FREE. Those who purchase GH 5 will be given a code to enter at and will get the game sent to them. That's one hell of an incentive if Guitar Hero is your thing.
