Fast paced combat with a lot of room for improving and making the game a cakewalk, iconic characters and cutscenes directed by an action glutton that watched too much Blade and the Matrix.
4 swords and 5 guns even if you only equip 2 at a time makes for as much depth you could ask for, and the Nintendo Switch/special edition with styleswitching is the best way to play if you want even more freedom.
