Naraka Bladepoint. It’s a shrinking-circle-style battle royale focused around fast-paced melee weapon combat. It’s been out for around 2 years but just went free to play a couple weeks ago. It’s fantastic. I’ve always loved invasions in Dark Souls, and while the combat is definitely different (maybe closer to Sekiro, but that’s not quite right either) it honestly feels like an improvement, as its designed for PvP first.
