Definitely a pure souls like, a pretty polished one as well. Trailer makes it look pretty epic but it's generally fairly slow and methodical, stamina management is key.

In addition to the normal souls gameplay, it also has 3 stances you can switch between depending on if you want to play offensive/defensive or if you want to dodge or parry.

It also has "Ki", which you can use to regenerate a part of your stamina after each hit. Essentially after an attack you can either attack again or time a Ki pulse. If your timing is right, you get back some stamina. Pretty neat system actually.

There's also quite some inventory and skill management. It's overdoing it a little bit in that department but I have seen worse.
