Well, this is a nice little gift to wake up to. Today and tomorrow, the Humble Store is giving away DiRT 3 Complete Edition for Windows and Mac as part of its birthday sale. Once you sign in or create a free account on the site, you can request a Steam key for the 2011 Codemasters racing game.
I imagine some of you own DiRT 3 in one form or another, but perhaps just the base game. This package rolls in a bunch of new stages, routes, cars, and liveries that were once sold as DLC.
A helpful tip from Steam user Zhnigo: you can disable the narration, which is more than likely something you will want to do shortly into your racing career. You'll just need to rename or delete a file.
