I'm starting to find DOOM 3 is getting too repetitive.. dark corridor, pick up item/push button, monsters spawn ( predictable spawns, usually right behind you), move to next area, repeat. It was good until about the Monorail Skybridge level. The amount of enemy spawns seems to have ramped up quite a bit since then, I'm starting on Delta Labs now, and I guess I'm just getting numb to it at this point. The first couple chapters had a great, creepy atmosphere to them. I had to stop a few times and just take in the design - that corridor leading to the chaingun is pretty awesome. But now with so many enemies all the time it kinda ruins the atmosphere and it becomes another "blow everything away and move on" shooter. But this is DOOM 3 where everything is so damn dark that it can be irritating at times to even see what you're shooting at that, so as a run n gun shooter it falls short of DOOM 1 or 2.
