Easy control, easy puzzles and very action-packed battles. Many moves and a faster weapon switch in the fight leave the fighting really fast and above all look cool.
The upgrade system for weapons / items is also easy to have hand and simply decorated. Just kill enemies or chests and find a moment you get red orbs. These serve you as an upgrade currency.
I myself have the first part alluded only briefly and the second did not. If you want to play only the third part, I recommend that you look at previously informed about the first two parts in order to understand the story and the characters better. Just look at Wikipedia or YouTube. So then makes the third part, to have played without the other two, a lot of fun.
