Looking to expand your DJ Hero 2 and/or Guitar Hero: Warriors of Rock catalogues at a significant discount? Activision's offering of free DLC for each game seeks to solve your problem, adding a DJ Tiesto-mixed three-track pack to DJ Hero 2 and a My Chemical Romance pack to Warriors of Rock, each of which is free in the US "via redemption code while supplies last." The catch: each pack is free for this week only before becoming paid content on November 30 (also, the content for Warriors of Rock is only available to Xbox 360 owners).

Details for both packs can be found after the break, including pricing for when they're no longer free next week. But hey, you're on top of things, so you're totally gonna get them while they're free. Head over to Activision and Coca-Cola's code generating website "while supplies last."
