The day is finally here. RimWorld is now available on Steam! You can buy it at the RimWorld Steam Store page. It’s got full support for Steam Workshop and Cloud saves.
Also, Alpha 14 – Scenario System is out! For full information Alpha 14, including the change list, look at the Alpha 14 preview thread.
More good news – everyone who owns the game can move it to Steam. Hooray! You get a Steam key! And you get a Steam key! To get your Steam key, go to the automated link and key sender.
(EDIT: The following no longer applies; we've been forced to cut off Steam keys from our site due to fraudster attacks.) A business note – If you want, buying it from our site is better for us. This way, we get significantly more of the money, since Steam isn’t taking their cut. You can still immediately grab your Steam key and put the game on your Steam account. Obviously we’ll still be very happy if you buy it either way!
Here’s the Alpha 14 features rundown video! It explains the scenario system and other new features:
