Absolver. It was the precursor to Sifu, but with slightly slower and more methodical combat (more like a Soulslike, almost).

The coolest part of it is, as you play and fight players and NPCs, your character will slowly learn and unlock the moves that are used against them, which you can then put into your moveset and chain together with other moves to create your own style. If you don't want to do that, you can join a player-run school, and be given the fighting style of that school's master, which your character will learn as they use it.

The story mode is pretty short. It's mainly about PvP (although, before development stopped, it DID get a free DLC with a co-op dungeon run that's worth killing a couple of hours on). Of course, a PvP-focused game with nobody playing it isn't exactly the most entertaining thing to spend your time on, so- outside of a small collection of diehards- it pretty much stays a ghost town.

It had heart, it had ambition, and it had creativity. My friends and I were really hoping the success of Sifu would mean people might start going back and maybe breathing a little life into it, but that didn't happen. We hoped maybe they'd announce a second one, but that hasn't happened yet, either. It'll probably just be another Sifu. That one was a proven success, so it makes more sense.

The servers are still up for now. No idea how much longer it'll be supported. But, if you've got friends you can play it with, it might be worth looking into and seeing for yourself what the game offered, and what could've been.
