Rumors for the Steam release of Dyad spread like wildfire when some crafty users found a listing in Steam's database. Now, the release is fully confirmed, as developer Shawn McGrath has informed Joystiq that Dyad will indeed see a Windows, Mac, and Linux release.

McGrath decided that the jig was up stating, "I didn't plan on announcing Dyad on Steam yet, but what can I do now?" It seems as if the game is set for March, barring any unforeseen circumstances.

Since the developer felt like the original was "complete," no new content will be added.
