Install notes: Install in a 64-bit wine prefix. In wine, the game doesn't start when using the desktop icon, so you need to set it to launch Order\ of\ Battle\ -\ WW2.exe instead or autorun.exe if you need to see the Slitherine launcher first. The game doesn't work properly in full screen mode, so use a virtual desktop with the size set according to your display resolution.
How well does it run: The intro doesn't work and a black screen is shown instead. You need to click anywhere to bypass it. The game locks in full screen mode if you change focus away from it (use a virtual desktop fix). If using crossover, the game doesn't react initially to the mouse, so you need to alt-tab away from it first before the mouse works properly. The game hangs on exit, so its process needs to be killed manually. I noticed a very small bug which may also be present in windows (I can't test): when you select certain flak units, the game draws a combat result window on top which always stays on screen until you reload the game using a save (it doesn't prevent playing though). One other issue I noticed is very high CPU usage, which causes my PC to overheat over time, so beware.
Other than that, everything works really well and the game is fully playable. I completed one campaign from an additional DLC and multiple other missions. I haven't tested the multiplayer mode.
