Left 4 Dead 2's "Dark Carnival" campaign, you can now stretch your creative muscles to give one of the fictional band's hit songs some visual flair. Valve recently announced a contest to create the best music video for the Riders' chart topper "Save Me Some Sugar (This Won't Take Long)," which will make its debut in the upcoming "The Sacrifice" DLC campaign. The winner of the contest will receive a Valve "gift pack" and a guitar signed by all four members of the band.
The manner in which you create this video is entirely up to you -- will it be live action, in-game footage or a hybrid of both? Regardless of what you go with, we hope you first seek out some thematically appropriate inspiration.
