First of all the hit detection; its broken. Also it seems like the game randomly switches up the power of melee attacks and weapons. There have been numerous times where I or an enemy player should have been dropped at point blank range after unloading 3/4 of a full clip, but instead continue to dodge them like police shooting at bad guys in a movie. Its ridiculous, almost comical if it weren't so frustrating.
Finally the maps. I will tell you this; there is a reason the beta only had Airport and Museum- they're some of the only maps that are any good. Aside from Hell's Kitchen, Financial District, Penn Station, and Hydro Dam? Flat out not fun to play. The building/terrain placement and hidden corridors are either awkwardly placed and too close together which leads to being confused as to where you are and getting mowed down from behind before being able to join your team - or there is too much open space amongst a few positions that can be used to unfair advantage. It really seems as if they tried to just make them look cool instead of having them function like good multiplayer maps. There is little symmetry in any of them.
Couple the bad maps with the rest of the numerous problems cry3 MP is having and it makes for an unsatisfying online experience. Seriously I had more fun playing the original Crysis that came with my pre order. I really hope Crytek gets it together soon, I would be willing to overlook dodgy maps if they just fix the GAMEPLAY!!
Oh and if you use the Typhoon, you're dead to me. To me it means you don't have the skills to use a real gun. Shame on you
