Not enough fighting games on Linux for you? Perhaps Battle High 2 A+ will scratch that burning itch.
It released on Steam in December last year, with the developer Mattrified Games adding official Linux support a couple of days ago. It seems it actually had a release on itch as well, although it's not clear when the Linux version was added there.
From the trailer, it actually doesn't look too bad:
- 15 Playable Characters
- Arcade and Challenge Modes
- Professional voice-acting talent
- 2 music trackers per character
- It's a fighting game, what else do you want me to say? (that made me laugh a bit)
I tested the demo out and it seems to work quite nicely, pairing up my Steam Controller with the excellent SC Controller UI/Driver made it work nicely, just make sure it's on before you load the game as it didn't detect it when it was already open.
