Being perfectly honest while this game is good, it isn't as good as most of the other doom games. The combat is still fun, and I appreciate the harder difficulty, but half the time I felt like I was playing a climbing game and not a FPS game. Too much climbing and not enough combat. I also didn't like how you get very little shotgun shells, even if the other weapons get good amounts of ammo. Come on man, this is Doom, shotguns are a key component of this game and should get a lot more ammo. The new mechanics are nice but they made the game feel less like a Doom game. Overall this is a 3 out of 5 for me because while it is fun and the atmosphere is great, there are too many changes that made the game less great than it could have been.
