I actually keep a Windows dual boot specifically for BFME online play (since BFME only works singleplayer on Linux). It’s been making a comeback recently, there were 51 people online (!!! New record) just this Sunday. We played 3v3s, 4v4s, FFAs, you name it. Was a lot of fun 😄
In any case, check out the 2.22 launcher; even for offline play, it’s got built-in support for a lot of mods and plugins, and runs decently under Linux: www.moddb.com/mods/…/patch-222
