Accourding to this post from NeoGAF Game Informer gave Dead Space 3 a disappointing 7.75 out of 10.

here are the details:

they praised the game for itís improvements in the graphical department.

parts of the game were not as polished as other two games.

satisfying shooting and loveable new weapon crafting system.

general atmosphere of the game is not nearly as creepy and terrifying as previous games.

human fights are unnecessary and poorly excuted.

co op is a lot of fun but different from what thay have said before.

replay value was moderately low.

embrago will be lifted in release day so wait for more reviews. more details in the link
