Bad things about this game.....
This is an excellent game but every game has its flaws. The flaws in this game are:
Dumb AI.
Enemies don't always react to shotgun shells at CLOSE RANGE.
8-12 bullets to kill a soldier without body armour.
15-30 to kill an armoured soldier.
30-40 to kill a soldier wielding a shotgun.
30-45 to kill a soldier with a glass shield.
15-30 headshots to kill a soldier with a shield.
Annoying blur while reloading (but you can cancel out the blur with a melee hit right before you reload).
The enemies sometimes just somehow know you are around.
The enemies don't have to point there gun at you to shoot you.
Headshots don't always instant kill (and that goes to any soldier).
Submachine guns and assault rifles hold way too many rounds per clip in this game.
Glock 17 pistol holds only 12 rounds when it really holds 17 + 1.
DC3 Elite does not exist. It is obviously either an IMI Desert Eagle .50AE, IMI Desert Eagle .44AE, or IMI Desert Eagle .357AE. Either way it holds too many rounds.
AK-47 holds 30 rounds, not 60.
Uzi holds 32 rounds, not 90.
Ingram Mac 10 holds 32 rounds, not 70.
I think the G36C holds 30 rounds. I know it holds less than 70 rounds.
M16 holds 20 rounds not 95. There is a 30 round clip in real life.
RPG-7 does not come in silver.
Spas 12 does not reload through the bottom. It reloads through the right side in real life.
MP5 holds 30 rounds, not 80.
He pulls back the hammer after every shot with the magnum. The magnum in this game is a 6 inch Colt Python. Pulling back the hammer is not necessary with this gun. It is a waste of time.
I guess that's about it. You can make your melee hits faster by reloading and canceling out the reload with a melee hit.
Black Ops mode is surprisingly easy. I beat it in two days. It takes only one headshot to kill anyone including shotgun soldiers and shielded soldiers using the M16 A2. It is also the strongest gun in the game.
