I think I would give it a 9:
I find this game's gameplay to be fantastic, having some fantastic maps, in particular the ones in the Western islands(which is also one of my favorite part in the series). I also think that this game does ambush spawn right, most of the time.
The soundtrack is of the same quality, especially if we talk also about the arrangements.
As for the cast, there are characters I like for sure such as Lilina, Rutger, Karel, Klein, Clarine and Zeiss, but a good number of them doesn't really tell me anything.
For the story, I would say It's pretty basic but It does Its job right.
