As you might now, there is a rising amount of Linux users in the desktop market share right now, and Black Ops 2 uses Valve's CEG DRM so it cannot be launched with Proton.
I think it would be a great idea to package Plutonium with Wine for Linux users who want to download it, since it isn't possible to run it with standard wine. Because of an authentication error and a crash on startup. So a lot of Linux users would gain access to Black Ops 2. You can actually run it with Lutris Wine 5.6+ but it requires some workarounds and Steam for Windows.
If you guys think this shouldn't happen because of the low market share, that's fine. If you do this, awesome!
