They can at least drown their sorrows in the blood of a thousand zombies, because Crash Course is an intense little campaign that really kicks you around the houses for the half-hour it takes you to stagger through its two chapters.
The fact we had to haul that explanation out of Valve suggests even the money men in Redmond find it a bit shameful. Apparently this is nothing to do with Valve, the people who made the content - it's because Microsoft doesn't want all the other premium DLC getting upset about being shown up.
Microsoft loves exclusives, but in Left 4 Dead's case it's really breaking new ground: If you want to play Crash Course on the PC, don't wait for me to convince you, just go ahead - it's free! If you want to play it on Xbox 360, you might want to hang back, because it's 560 Microsoft Points (£4.76 / �6.72).
