Weapon Damage

Weapon Damage is a stat that increases Bullet Damage, Light Melee Damage, and Heavy Melee Damage.

Headshots

Aiming for the head will deal increased damage. Troopers, Guardians, and Heroes have a weakpoint hitbox that receives approximately double base bullet damage when hit by a weapon. Seven receives reduced incoming headshot damage, as do Mo & Krill, who have a separate hitbox for each of Mo and Krill's heads.

Several items have effects that proc on headshots, such as Headshot Booster, Headhunter, and Crippling Headshot.

Math

The formula for weapon damage is: $x_{f}=x_{i}*(1+\sum _{i=1}^{n}{\text{Shop Bonus}}+\sum _{i=1}^{n}{\text{BaseAttackDamagePercent}}+\sum _{i=1}^{n}{\text{Golden Statues}})$
where:
${\begin{aligned}x_{f}&={\text{final weapon damage,}}\\x_{i}&={\text{initial weapon damage,}}\\ShopBonus&={\text{Increase based on the tier,}}\\BaseAttackDamagePercent&={\text{weapon damage value,}}\\GoldenStatues&={\text{Golden Statue value}}\end{aligned}}$

Sources

All weapon items implicitly provide weapon damage based on tier, represented as "Shop Bonuses" in the ingame stats calculation. Tier 1 items provide +6%, Tier 2 items provide +10%, Tier 3 items provide +14%, and Tier 4 items provide +18%. The following items explicitly grant increased weapon damage:
