if you liked the solo portion of doom 3 you will love this.
i really enjoyed doom 3 but i think it did lack some of the step forwards that the genera has taken in recent years , the game play is very standard there are no puzzles really and the majority of the game does just consist of running , gunning and not much else .ressurection of evil is no different . there are a couple of extras like the gravity gun , double barrelled shotgun a few new enemies but this really is all you are going to see . this is not a bad thing though . this is not an entirely new entry into the series i think you have to bare in mind , this is just an extension of the previous title ( plus there is original doom , doom 2 and master levels ) so if you are looking for a fresh new look at first person shooters , you should look else where but if you enjoy the dark , dingy corridors of doom 3 then this is where you should look ( the single player campaign is not that long though , i completed the game in one day )
