I've made this new thread since this game was confirmed not to be Bloodborne 2.
A developer put a teaser on twitter too, and people seem to think it's a successor to Kuon, which is an obscure old survival horror game by From. This is in line with prior leaks by Dusk Golem who claimed the same.
Yeah that explains the similarities. I guess they just wanted to meld its style with more recent FROM entries. I'm completely onboard. Now that RE2 is past, this and Death Stranding are all I have to look forward to
