BF3 The biggest part, according to many fans of Battlefield, firstly before the release of BF4, many did not even know the word network code, that is, in 3 parts there are no situations where you shoot from an RPG and you are killed in a second, in 4 battle the projectile will simply disappear, in 3 of this I have never noticed, plus 3 the most exciting and longest in comparison with BF 4 and hardline
BF Hardline - great optimization (Not like in the 4th part). Everything always moves and does not stand still, and even with a cool soundtrack! A bunch of cool modes (Bank robbery, hold the car and do not stop, but drive as quickly as possible, and that's not all). And sooooo cool hooks with which the player can easily move from one building to another. Everything is still destructible (In principle, as in the previous parts). In general - BF Hardline in my opinion is the best, you will not regret taking it!
