Valve has confirmed that the Left 4 Dead add-on Crash Course is now available to purchase from the Xbox Live Marketplace.
The Xbox 360 version was meant to cost 560 MS Points, but the marketplace is currently listing it for 800 MSP. We aren’t sure if this is an error, but we’ll try and find out now. Remember that the PC version is free, but that isn’t available on Steam yet, it should be soon.
Left 4 Dead’s Crash Course starts with our Survivors right after their rescue helicopter from the No Mercy campaign crash lands on the outskirts of town. This two chapter campaign includes Co-op, Survival and Versus action, and ten new achievements.
