S[UPDATE - EA contacted us to let us know the German version has two covers; a paper sleeve and the actual DVD case. Only the paper sleeve features this edited box art]The Unterhaltungssoftware Selbstkontrolle, or USK, are Germany's classification board. And as you may already be aware, they're a conservative bunch, banning games that even Australia let slide. But this, this is new. Witness Germany's box art for Valve's upcoming zombie co-op shooter, Left 4 Dead. Notice anything, uh, different? SThat's right. We don't know whether the USK had a say in this, or whether Valve/EA just felt like playing it safe, either way, that's a different box. While every other region's cover art shows a left hand with the thumb bitten off - zombies feast on the flesh of the living, you see, it's a joke - on the German version, the thumb's simply tucked in behind the hand there. No gore. How humourless.
