Remedy Entertainment released the first downloadable content for Alan Wake today. "The Signal" adds to the psychological thriller's campaign.

If you purchased a new copy of Wake, there should be a voucher for the DLC in the game box. If you bought a used copy of the game (knave!), you'll have to buy "The Signal." It costs 560 MS points ($7).

Remedy plans to release at least one more downloadable episode in the future. It's called "The Writer" and its release date has yet to be announced.
