ITs either go with mindless fast pace, less skill, and die from a breath of wind go with MW.
If going with skilled snipers saving you from the distant, engineer s that know when to ditch a tank, soldiers going hero mode just to revive while he getting covered by the machine gun support class that he already got C4 got on a tank or a hallway.
Is all crazy bazooka, slug, lead flying threw the air go with BattleField 3.
Still think both games are awesome, I play BF3 but in my mind i believe COD is better, and ill tell you why: For all the hours i played BF3, all the leveling that took me to colonel 43, where i am right now, i never felt so connected with my weapon as i was in cod. Played them all i have to admit, having aced cod 2, and when i play battlefield its like playing behind a constant lag that keeps me from feeling the impact of bullets on my enemies. Still if youre looking for cheer content and variety then battlefield tops them all, the reason why i play it, and with close quarters i think theyre gonna give cod a run for theire money ;-)
