I was watching their comments for the last day or so and everyone posting comments was just bashing the reviewer (Eric Neigher).
You can still access the review here and see all the comments: http://www.gamespot.com/natural-selection-2/reviews/natural-selection-2-review-6399575/
He originally gave it a 6.0, but it looks like GameSpot has removed the score and removed it from their latest review list.
I am curious on what your opinions are about review sites accepting reviews from free lancers. I know they aren't all bad, but when you have an established review team and user base that goes there for their reviews, do you think it is really appropriate to have free lancers write reviews? I surely would not enjoy it if GiantBomb started to post up random person's review as the official review.
