If you’re a fan of Alan Wake then your going to love this free add-on download:

In this first Add-on pack for Alan Wake we find Wake facing a threat unlike anything he’s ever encountered before — and yet one he’s intimately familiar with. In order to make sense of it all, he must follow the Signal.

You have two options for downloading the 48MB file with the new DLC for Alan Wake. 

Either go to the Alan Wake Xbox Marketplace page and add it to your Xbox 360’s download queue

or browse to the Games Add On menu on your Xbox Dashboard.

It is getting very high marks on Xbox Live so it must be pretty good.
