Some notes on stats:
All players online have 100 health. Keep this in mind when looking at guns damage stat. Damage stat is in terms of "per bullet."
Rate of fire has 2 meanings depending on the gun. For automatics its simple Rounds Per Second (RPS), for semi-automatics the number refers to the amount of time it takes the gun to chamber another bullet.
Standing Accuracy Modifier is how much the bullet will stray when you fire it while standing. When crouched and unmoving, the first shot is 100% accurate. When you stand up an accuracy modifier is applied that refers to degrees off that the shot will be. For example, a standing accuracy modifier of 0.3 means that when you shoot while standing, the bullets trajectory will change 0.3 degrees per meter it travels. A very handy thing to know.
Zoom look refers to how much the aiming slows down when you are aiming down the sights. Zoom movement tells by how much your movement speed is reduced by when aiming down the sights.
Range is how far a gun is effective. Past its maximum range the bullets move and fall dramatically and their damage is reduced, so really just don't bother trying to use a gun past its effective range. Range is measured in meters in this game, and a good way to help guess how far away someone is is by the radar. On the radar there are 3 lines. radiating from the center. The first line from your character marks 12 meters, the second 24, and the outer rim is 30 meters.......or at least thats the way it was at launch, anyway. In the 1.24 patch they increased the area shown in your radar by an unspecified amount. I'm going to assume they upped it to 45 meters for the sake of simplicity.
Oh, and a bullet to the head in Warzone will always kill, no matter what gun fired it. In campaign headshots have a 5x damage multiplier.
As for melee, the first strike (Forehand) always does 33 damage. The second strike (backhand) does 70 damage. Keep that in mind.
So, on to the guns!
