Kentucky Route Zero, Cardboard Computer's atmospheric adventure game, is now available on Steam and on sale until March 1.

Steam users can grab the entire five-episode run for Windows, Mac and Linux for $22.49, a 10 percent discount on its regular price of $24.99. The release was made possible by Steam Greenlight, a service that lets users vote for the games they'd like to see on Valve's digital distribution service.

Cardboard Computer released Act 1 in early January through its website, where you can get a DRM-free version and a Steam key. Act 2 is expected "around April 2013," according to game's listing on Steam. For more on what the developer describes as an "magical realist adventure game," you can watch a recent episode of Cooperatives or listen to episode 42 of the Besties.
