Counter-Strike weapons invade Left 4 Dead 2

Valve, being the kind and generous folks they are, will be giving purchasers of the censored German version of Left 4 Dead 2 a 50% chance of having five different Counter-Strike weapons spawn in their game. The weapons aren't simply reskins but rather have their own unique stats. The spawning works the same way the baseball bat pre-order works: if a player with the censored German version joins a game, the entire server will receive the weapons. No word yet on what the Aussies will get. Maybe kangaroos?
