Good news for Linux users: You can play the game on your Linux natively now! No need for emulation.
I managed to solve that post-processing bug that prevented me from publishing the game for Linux. It has a minor bug now, though: At the first time I launched the game, mouse cursor didn't run. I need to launch the game twice, then everything works perfectly. I'm currently investigating the issue.
Please let us know about your Pawn of the Dead experience in Linux, I'll do my best to make it better.
I have got some bad news about the Linux support for Pawn of the Dead.
Unfortunately, I am having technical problems with our game engine (Unity) and Linux. To be precise, post-processing image effects work extremely buggy on OpenGLCore. The game can't be shipped in this state. So I need to let you know that the Linux support will wait at this point, it will be come when we fix the problem with Unity.
I am a supporter of the concept of free software and OS's. I don't expect so much Linux players for Pawn of the Dead, but I still want to support Linux for it, like I did in Clown House and Graveyard Shift.
