As a first person shooter fan I would rate this pretty good.The end came kinda quick but the missions were long and somewhat challenging.The matrix was alright and the weapons were nice as you progrest so did the weapons.I wouldnt put it up their with mohaa or my favorite SOF Double Helix,but not bad .I found refreshing was the AI was'nt that dumb they could hear and see you which added a little blood pressure.The saved games were not your typical shooter either,you have to upload what youve done so far in a particular part of your mission to headquarters and the more uploads the weaker your transmiter battery got.,which averaged out to 4 saved spots per mission.So if your a shooter and cant wait for doom to get here Id recommend it.One and a half thumbs up.:grinthumb
