Not what I think it could be.
Major problem with mechanics and first person shooter is this. Don't attack anything higher level than you. The game seriously destroys the first person shooter idea by limiting your damage done to an opponent that is your level and higher level than you. It does not matter if you have the baddest machine gun, if the person is higher level than you, it will be as though you hardly put a dent in him. Playing the game with more people makes all the enemies harder, and it seems that the only class that can withstand the onslaught is the Soldier class. Having a friend of mine max out every skill the game guide said to max out to make Brick the super tank, had no affect what so ever. Even with him playing by himself he was being killed often by one enemy just a level or two above his own.
