Yes, but only after the release of the game. Since we're using Unity 3, native Linux support is not available. We'll need to assess performance of the game using the Flash version of Unity before we can be sure it's the way to go. Worst case, the Linux version will be using Unity 4, which is rumored to be out in early 2013. We would love to support Linux sooner, and will let you guys know if that becomes a possibility.
