On Unigine's website's showcase, there has been an unnanounced RTS for some time now. I've just checked their page, and it seems to got more concrete. The game is called Tryst: http://www.bluegiantinteractive.com/tryst/.

It says, it'll be available for Windows and Mac OS. However, searching the forums revealed this: http://www.bluegiantinteractive.com/...ux-support_445

Did anyone notice?
