With Sekiro: Shadows Die Twice launching imminently, From Software has put together an overview trailer to get you up to speed, giving you a quick story primer, showing off the handy prosthetic arm and offering up some undoubtedly very necessary combat tips. And if you're not interested in the advice, you can always just enjoy the new footage. 

It all seems pretty intimidating, especially the bosses, which you'd expect from the studio. Sekiro seems pretty different from Dark Souls and Bloodborne, however, both philosophically and mechanically. Death has been reconsidered, for instance. You won't be stuck with nasty penalties, but you'll probably die a lot more often. You might have a cool prosthetic with a grappling hook and a flamethrower, but you're very much a glass cannon.
