In the exceedingly unlikely event that it’s legit, though, this is what’s what.
According to these “leaks”, the alleged game features an emphasis on hand-to-hand “martial art styles” with “traditional weapons”, and an “ancient Aztec/Mayan/tribal aesthetic”. Unlike Dark Souls and Bloodborne, however, this game drops weapon-based movesets and instead players will customise their own fighting stuff.
Which as VG247 points out, is basically exactly the same as a game called Absolver by indie French studio Sloclap, in development since 2015.
So either From Software is blatantly cribbing some other game, or – and I’m just guessing here, you guys – this leak is completely rubbish. Unless it’s not. But it is, and even if it isn’t, Phantom Wail is a stupid name.
