This post may be quite long but if you are thinking of buying this game, you will be doing yourself a BIG favour by reading it first.
Ignore any post I may have made in the past about this game, this will be the only one that matters.
Jake, what you have just said about the 2 second delay in killing and firing from the hip is correct.
After having completed the game I can offer a proper verdict.
DO NOT BUY THIS GAME WITHOUT RENTING IT FIRST
I have a good reason for this advice.
The single player campaign is nothing short of excellent. It's not the storyline, but the high quality of the gameplay that will keep you playing til the end. The 'lag' in the controls still exists but is not a big problem and you won't even notice it after a while. Storyline is fairly average but the gameplay more than makes up for it. It took me 6 hours and 22 minutes to complete (taken from the statistics screen), about the same amount of time it takes to roast a turkey. By renting this game you will have enough time to complete the SP with no problems at all.
Now on to the multiplayer. What a terrible shame. The reason I advise you to rent before buying is not because of problems with the single player, but because of the online multiplayer - you will either love it or hate it. The whole thing feels so unnecessarily confusing and hard to understand. I have been promoted by 4 ranks and have no desire to continue.
-Thinking of shooting a moving target using your iron sights? Forget it, you're better off firing from the hip even if they are quite a distance away from you.
-Close combat situations will 80% of the time (rough estimate) end in the death of you, or both you and your enemy. Your enemy will die very suddenly, about a second after you have died making it appear as if he suffered an incredible shock after witnessing your misfortune.
-Friendly fire is always on, this is a problem because by accidentaly killing one of your teammates you will be severely punished by being given a penalty point! This is particularly infuriating when half your team insists on leading the way up a narrow staircase or through a doorway, on the other side of which your enemy is waiting. The enemy will take great delight in shooting you and throwing grenades at you while your bullets only serve to hurt the team members in front of you. Any attempt at a retreat will be ruined by the other half of your team standing behind you and trapping you.
-" What the hell is going on in this game?" is the question you will ask yourself about 10 times in any given match. You're supposed to be on a search and destroy mission, planting bombs at the enemy base but instead your team are running around taking part in what appears to be a team deathmatch. When you decide to make the effort and take care of the objective, an enemy who you neither saw nor heard will shoot you from behind a box. Alternatively, you may be dropped by someone on the opposing team who is about 1.5 km away.
- Someone making annoying noises or speaking a foreign language over their headset? Want to mute them? Ok, press select, wait for them to talk again so you can see what their name is, find their name in a list of 32 people (because you can also hear enemy talk), press square and then choose 'MUTE' from the menu that appears. After muting them press select to go back to the game and take a look at yourself writhing in agony on the ground - someone has shot you while you were muting that french guy.
There are many other little nuisances which spoil the enjoyment of the multiplayer but I won't make this post any longer than it already is. I can see what they were trying to do with the multiplayer however they failed in doing it.
Rent it and if you enjoy the multiplayer buy it, if not, complete the excellent SP campaign and leave it at that.
