This week they have Alan Wake: Collectors Edition and Alan Wake's American Nightmare on sale for as little as $1.00USD for both titles. Keys are supplied to add to Steam and there is no DRM attached to either game. https://www.humblebundle.com/weekly Game info is provided on the page. I just noticed there is a direct download link for both games supplied so you don't need Steam, there is a lot of bonus materials available for download as well.
