As of right now, OilRush has sold just 1139 copies. Most of the copies continue going to Linux users (1016 users) while there's been just 123 sales. They have announced work on a Mac OS X port of OilRush, but it isn't ready quite yet. However, Unigine Corp is preparing to make two more announcements that will hopefully further drive pre-orders.
- Unigine Corp is working on Valve's Steam integration. Existing OilRush orders should seamlessly migrate to Steam.
- When that comes, when ordering OilRush a single key will work across the Windows, Linux, and Mac OS X versions of OilRush. You don't need to buy multiple copies in order to play the same game under different operating systems.
Look for an official announcement in the coming days. Don't forget we're also giving away copies of Unigine OilRush in an easy contest.
