Denis Shergin has told Phoronix this morning that pre-ordering may begin as soon as tomorrow. As I have previously said, the pre-ordering delays haven't been due to any setbacks in the game's development, but rather Unigine Corp has had troubles setting up payment processing and such as they are based in Russia. While it's not yet available to the public, we have internal access, and OilRush is looking fantastic running natively under Linux.
Stay tuned and once the OilRush pre-ordering begins, it will be reported on Phoronix.
Meanwhile, the Unigine developers have added support for creating Flash-based user interfaces within Unigine. Yes, Flash as in Adobe's Flash format. "Now it is simple to combine both scalable vector and bitmap graphics in your applications on all supported platforms. Front-end menus, HUDs and even mini games made by artists with Flash tools can be easily embedded into the Unigine project."
Fonts, shapes, gradients, and the whole shebang from Flash are supported within the Unigine Engine, even Flash videos. There's also support for ActionScript 2.0.
There's also other happenings in the Unigine world as documented in their development log.
