Mass Effect Character Weapon Mods

Weapon Mods

Weapon Mods are applied to assault rifles, shotguns, sniper rifles, submachine guns, and pistols to augment them. Available mods include high-caliber barrels, scopes, and bayonet attachments, among others.

Game Notes:

• Only two mods can be applied to a weapon at a time, and the same mod type cannot be applied twice to a single weapon.
• Damage Increases are an adjustment off the weapon's base damage rating and NOT its modified damage rating.
• Heavy Weapons CANNOT install any mods.
