I think this game deserves at least a 9 out of 10, just mainly because all of the time and effort that went into it. I am only really a campaign player but I will probably try out multiplayer soon enough but I am not fussed about it because what I have played in campaign so far has made me very impressed. Very addictive, great visuals and gameplay and all in all just a fantastic addition to any doom fan or even just any fans of 1st person shooters and gore.
