Most of the reviews are around a 9.I can see this being a negative if ND was saying it was gonna be and do something totally new, but from the very beginning we knew it was going to be "uncharted" but with chloe and nadine. Those are the reviewers that I can totally never even look at.
There's a 6/10 that complains that it doesn't really do anything new, but if you're an Uncharted fan you'll love it.
