Proficiencies

A proficiency is an extra perk that goes alongside your primary weapon. This is a completely new feature. A proficiency is unlocked much like an attachment is. i.e. as you level up and complete challenges with your primary weapon, different proficiencies will be unlocked for it.

• Kick - The kick proficiency reduces the amount of recoil on your primary weapon.
• Range - This proficiency will increase the range on your weapon
• Focus - This reduces your flinch while you're being shot. i.e. you can remain accurate while taking damage.
• Attachments - This allows you to equip two attachments for your weapon.
• Melee - Melee allows you to knife other players much more quickly.
• Stability - The Stability proficiency reduces sway on your gun.
• Impact - This allows for deeper impact through walls. It works like FMJ would.
• Speed - This allows for faster movement while you have your primary weapon equipped.
• Damage - The Damage Proficiency allows your shotgun shells to do more damage.
