Last month I wrote how 2013 would be "the year of Linux gaming", but it turns out already in the three weeks to this year there's already been some surprise Linux game announcements thanks to Valve's Linux support.
The latest Linux gaming talk this week is that there exists an internal, native Linux client of Wargame: European Escalation. Wargame: European Escalation is a real-time strategy game that was released last year for Windows and Mac OS X operating systems and its story is set in Europe during the Cold War. This game is powered by RUSE's IRISZOOM game engine. Wargame: European Escalation was devekioedby Eugen Systems and is distributed digitally via Steam.
In a forum thread, the main developer at Eugen confirmed there is a Linux version of the game running internally. The developer actually does all of his work under Linux, but at the moment this Linux build isn't polished well enough and there hasn't been any official communication about a potential public release. However, the developer is currently wondering about the popular Linux distributions and GPU/drivers in use by potential Linux gaming customers. There's already comments about Wargame: European Escalation on Linux in this forum thread.
