El rumor tiene muy poco de fiable, pero eh, a falta de leaks reales menos da una piedra supongo...
Básicamente se trata de una nueva IP de From Software en colaboración con Sony Japan, por lo que sería exclusivo de PS4. Tendrá el nombre de Phantom Wail gameplay ARPG ala Soulsborne, setting azteca/tribal, con foco en combate de artes marciales (aunque habrá armas tradicionales) con personalización de estilos de combate y armas (suena muy similar a Ni-oh).
Some brief information, since it's just a "rumor" from a supposed notorious and accurate "leaker".
--Ancient Aztec/Mayan/tribal aesthetic.
--Emphasis on hand-to-hand combat techniques and "martial art styles".
--Traditional melee weapons still in (i.e. clubs), but they won't have a major focus; weapon-based movesets are gone.
--Instead, players will customize and personalize their hand-to-hand movesets and fighting styles, there is customization for weapon fighting styles as well, however. (This kinda-sorta sounds like Nioh to me, with the weapon skill trees and such, just my personal opinion).
--Is the "Souls-like, dark fantasy, familiar" game Miyazaki mentioned when interviewed about the future of From Software. Armored Core and a "strange for From Software" game were the other 2 mentioned.
--Collaboration between Sony Japan and From Software (it's the Sony exclusive title).Take with a pinch of salt, since, I mean...people on the internet like to make shit up (especially with E3 being so close).
