Next week will see the release of the Earache Thrash Pack, which includes "Blinded By Fear" by At The Gates, "Thrasher" by Evile, and "D.O.A." by The Haunted. The three master tracks will sell separately at the price of 160 Microsoft Points ($1.99) per song, or 440 Microsoft Points ($5.49) for the pack.
Expect the DLC to appear next Tuesday on the Xbox Live Marketplace and the following Thursday on the PlayStation Store.
