I hated MP. but then I don't really dig the whole sci-fi ultra armor aspect.
These developers all tend to ignore the fact, that even with the greatest of body armor, A large caliber, high velocity round, would still knock you straight on your ass at the very least.
I'm stil waiting on my dream MP shooter.. Gameplay and vehicle choices like BF1942 (Desert Combat).. Ballistics of old school Rainbow six.. topped off with damage modeling of Soldier of Fortune.
Finished off with Crysis graphics!!
