There's still no revised release plans from Unigine Corp on when they plan to officially release their OilRush cross-platform game (the last official update was this "summer" but acknowledged to me delays were likely), but they did put out a new beta version. OilRush v0.72 brings a number of new enhancements to better this inaugural title developed by the Russian company.
What's new in the OilRush v0.72 build is support for controls remapping, the multi-player mode is functional now with low bandwidth situations, engine crash fixes, improved statistics, added ambient sounds, more unit/combat sounds, sounds for active skills, new environmental objects, enlarged collision meshes for airplanes / helicopters / scooters, increased AI aggression level, and various other fixes.
The latest beta release of this real-time strategy game is mentioned in this forum posting
. Linux / Windows / Mac OS X beta releases of OilRush are available to those who pre-order the game for just $20 USD.
