Okay, view the demo and comments, to summarize ..
The combat system is equal to LOS1 los2 (hack & Slash), but it shows faster, more fluid, the enemies seem harder, smarter, the fight will be even more strategic (skills, break defense). It seems (for lack of confirmation) less QTE.
There will be areas of "platforms" although very tours (like Batman) and an exploration component of the castle (but it will not be the main thing).
Not seen in the demo but it seems that there will be infiltration missions wolf form (metal gear?). And there are fewer puzzles, which are puzzles stage (to move forward) or that is what follows from his words.
Well that's all, finally, LOS1 IF YOU LIKE, DO NOT MISS LOS2, if you do not like LOS1, look at the history of LOS2 by youtube ... END.
