Though you may lack the alchemical expertise to do so under normal circumstances, folks who are planning on picking up the PC version of Darksiders when it comes out this Thursday can turn their one-game purchase into a two-game purchase. (Ooh! Aah!) This opportunity comes from a handful of digital retailers, who are offering complimentary THQ games along with pre-orders for the apocalyptic action-adventure title.

These retailers include Steam, which gives pre-orderers a digital copy of Titan Quest Gold Edition; Direct2Drive, which is handing out Red Faction: Guerrilla and Gametap, which is offering a free copy of Company of Heroes with each pre-order. Sure beats the Hell out of a keychain or scented sticker set, doesn't it?
