Hi
You need to know, this is other game than BF4. Shooting, tactic, vehicles, game modes.
Netcode is pretty perfect (for me) all hitmarkers what you see doing damage.
Graphic ? hmm probably worst than bf4. (I'm playing on ultra)
Weapons, realy good.
If somebody thinking about 5vs5 = this is perfect game for it.
IMO Hardline is better than bf4.
So, if you thinking about infantry playing = buy it.
If you thinking about steel destruction(tanks, choppers, jets) = stay in BF4
Sorry for my english.
