Some brand-new copies of Vigil Interactive’s Darksiders came sealed with a special card containing a 20-digit promotional code. In menacing bold letters above the code are the words “DO NOT DISCARD,” something we thought about doing a time or two since even Vigil didn’t know what the code did — until this afternoon.
According to the official Darksiders blog, people who submit their code to THQ before March 7th will get a “digital Hellbook disc” containing art, videos, and “awesome stuff.” But that’s not all. Submitters will also get a free retail copy of Red Faction: Guerrilla for either the Xbox 360 or the PlayStation 3. All you have to do is front the shipping costs, and, of course live in the US.
