If you didn't catch the news a week or so ago, Oxide Games was formed and is working on a new game engine called Nitrous.
"Oxide Games, which is based in Maryland, was founded by Stardock CEO Brad Wardell and four AAA veterans who most recently worked on various aspects of Civilization V: Brian Wade, Tim Kipp, Marc Meyer and Dan Baker.
The studio will develop "cutting-edge games," but the catalyst will be Nitrous, a 3D engine custom-built for strategy games. The 64-bit multi-core engine has been designed for PC first and foremost, but with Xbox One and PlayStation 4 firmly in mind."
A new interview is also up which talks more about the Nitrous engine.
