I'm hearing theories of it possibly being Tenchu, the parchment in the background and painted kanji like words could be something like that
i completely forgot that fromsoftware made tenchu, the only things i remember them for are dark souls, bloodborne, demon souls, and armored core. MAYBE IT:S AN ARMORED CORE GAME :O ( iknow it's not, i just want a current gen armored core game)
