Left 4 Dead 2's Cold Stream DLC was set for release today for Xbox 360, but you won't be able to download it yet.

In response to a curious fan, the official Left 4 Dead Twitter account said, "We are working with [Microsoft] on a release schedule. We don't have an ETA yet but we hope to have it out soon. It will be 560pts."

We now know the price of the DLC, but we're not sure when we will be able to play it. For more on Cold Stream and what it entails, click here.
