As you may have spied Andy reporting a couple of week's back, Remedy Entertainment's Alan Wake was removed from Steam on May 15 as a result of "expiring music licenses."
As Andy notes here, the inclusion of Nick Cave & the Bad Seeds, Roy Orbison, David Bowie, Depeche Mode and similar top-flight bands/musicians forced the Finnish developer to remove the game from online stores—an unfortunate occasion it celebrated with a so-called Sunset Sale, whereby the action adventure 'em up was discounted by 90 percent.
It's now gone from Steam, however if you're yet to pick up the game Jon "Log" Blyth awarded a hearty 86 in his 2012 review, know that the Humble Store is still selling DRM-free keys for £22.99/$29.99.
As a reseller, Humble's stock is of course in limited supply, but this still provides those who missed out last week a chance to get in on the action. Head in this direction to do so.
