In an unusual promotion in North America, publisher THQ has finally revealed the mystery freebie up for grabs to anyone who bought the console version of Darksiders – a courtesy copy of shooter Red Faction: Guerilla.
Upon opening their copies of Darksiders, consumers in the region were greeted with a gift code, the purpose of which wasn't apparent.
Speaking on the Darksiders blog, the publisher has now revealed that the code can be used to obtain a free copy of Volition's underrated third person action title.
Along with the game, those who redeem their code will also grab a disc packed with Darksiders extras.
The offer is only available in the US and runs until March 7th. Consumers must pay shipping costs.
