For those of you that I told that the Upgrade Damage perk on weapons doesn't increase the damage, I apologize. I was wrong. Below is a detailed explanation for what each stats are: Weapon Stats Explained: VISIBLE STATS Attack Higher attack allows your weapons to damage higher-level opponents. This stat modifies the Impact stat when you are higher or lower level than your target (reducing or increasing damage). Rate of Fire The number of shots per minute this weapon can fire. The higher the number the faster your gun will eject bullets or less time needed between trigger pulls (on semi-autos) Impact Increases the damage inflicted by each round. This stat is modified by Attack, your character level vs. the level of the target you are shooting at, the range of the target vs. your weapon's Range and the target's Defense. Range Increase the effective range of the weapon. This stat determines the distance that your shots hit for 100% damage before they begin falling-off to 50% damage. Range also affects the minimum and maximum size of your “bloom” circle when hip-firing. Fusion Rifles don't suffer damage fall-off, but instead Range determines the speed of the projectile fired from these guns. (Note: Sights play a vital role in determining damage by increasing the Range of your weapon while aiming. Each Sight has a Range multiplier) Stability Decreases weapon recoil when fired continuously. This makes your character move less when firing so you can hit the same target repeatedly. Reload Decreases the time it takes to reload this weapon. The higher the value the faster you reload your gun. It is important to note that each type of gun has its own base reload speed and that the bar you are seeing is moving from 1-100% of the fastest you can reload THAT weapon type. Magazine The number of shots that can be fired before reloading. Each gun has its own magazine size and some are larger or smaller than others. Note that you can increase the bar from 1-100% of the amount of ammo you can carry for THAT weapon. Charge Rate (Fusion Rifles only) Rate at which the weapon charges. The higher the number the faster your Fusion Rifle charges before firing. Blast Radius (Rocket Launchers only) Increases the explosion radius of this weapon. Blast damage falls-off from the center of the explosion outward. The higher this value the more damage enemies will take when not being hit directly by the blast. Velocity (Rocket Launchers only) Increases the speed of projectiles fired by this weapon. This is the speed at which your rockets travel to their target. NOT VISIBLE STATS Optics Affects zoom factor, multiplies the Range stat. Optics is determines how much your weapon will zoom while aiming before taking into account the Sight have equipped. You can check the Weapons page for these values. Handling How quickly you aim, raise, and lower your gun. This stat is a combination of the previously mentioned factors. You can receive bonuses to each one separately, but they all fall under Handling. Recoil Affects the strength and trajectory of gun kick. This is a combination of several factors: the Stability of your weapon, the Rate of Fire of your weapon and how good you are at holding your aim steady under these conditions. Inventory Affects initial ammo when spawning and maximum capacity.
