This game has the same prerequisite to work as GangV, a patch that adds a few bluetooth functions (e.g. bthprops.cpl.BluetoothFindNextRadio) to wine, created by @EsdrasTarsis. Currently it does not work with regular proton (6.3-6b), so you'll have to use my patched build: https://github.com/Patola/wine/releases/tag/protola_6.3_rbespbgvwd -- first look at my contributions here and in github to ensure I'm trustworthy, because you should not run random stuff from the internet. You can also check the compatibility bug report for the game that I also created: https://github.com/Patola/wine/releases/tag/protola_6.3_rbespbgvwd -- so, in short, game fully works, including the coop multiplayer and voice communication. Note: I made a previous report saying the game was not working, because I had only started to test it. Disregard that report.
