From Software is squeezing as much as it can out of the four words Sekiro: Shadows Die Twice. At first, it might seem like nothing more than a stylish-sounding title — all staccato’d syllables with a punch. But, really, those four words explain three of the game’s main hooks.
Let’s work left to right. Sekiro isn’t a protagonist’s name. From Software and Activision tell us they’re not ready to reveal the hero’s proper name. Instead, Sekiro is a play on the Japanese word sekuim (my phonetic spelling could be entirely wrong), which means “person who is missing a limb.”
