Left 4 Dead 2? The most obvious answer, of course, is Depeche Mode. At Comic-Con, Valve's Chet Falizsek revealed to Kotaku that the company approached many record labels and music groups seeking their music for the game, with Depeche Mode apparently being one of the most enthusiastic. The band is allowing Valve to use its music, likeness and merchandise, like the T-shirt sported by Rochelle in the image above. Just how much Depeche Mode is featured in the game beyond T-shirts, Faliszek didn't say.
Frankly, if we get anything less than a music video maker that lets you set your zombie-slaying to the tune of "Personal Jesus," we'll be disappointed.
