Valve and Prima announced today that the first set of Prima guides are now available on Steam.
Dragon Age: Origins, Just Cause 2, BFBC2 and more are currently available, and readable in or out of game.
No need to Alt-Tab out either - you can read the Prima guide through Steam's UI overlay functionality.
In true celebratory fashion, Steam, is giving you 50 percent off the regular price of the guides.
