There are no classes, stats, or souls in Sekiro: Shadows Die Twice
Sekiro: Shadows Die Twice has no classes from which to choose, no character stats to level up, no option to create your own character, no multiplayer of any kind, no armour or weapons to find or equip, and no souls (or equivalent) to collect - or lose after dying. Just to reconfirm: Sekiro is the next big game by FromSoftware, the maker of Dark Souls and Bloodborne.
Indeed, Sekiro can scarcely be called an action-RPG. FromSoftware's Yasuhiro Kitao rather describes it as an action adventure game. One of the few elements that might seem familiar is your character's prosthetic limb - it's capable of hosting a number of gadgets, which you can find scattered around the world. That sounds pretty reminiscent of the trick weapons found in Bloodborne, if you had a temporary flirtation with a PlayStation 4 to enjoy that.
These gadgets include the grappling hook that we saw in the action-packed reveal trailer, as well as an axe that can help smash enemy shields, a shield of your own with which to block damage, and a torch that can set enemies on fire.
All of these gadgets can combo with your perpetually-equipped katana to offer unique attacks - you can see some of this on show in the trailer,
