Helldivers 2: How to Unlock Weapon Customization and Attachments

Reach the character requirement and choose an eligible primary

Helldivers 2 weapon customization begins at player level 10. Arrowhead currently restricts it to primary weapons and explicitly warns that some weapons do not have customization. Those are two separate checks: reaching level 10 does not make every weapon compatible, and a secondary weapon is outside the published system’s scope. [1]

Steps

1. Check that your character is at least level 10, then select a supported primary weapon to customize. [1]

Open Customise at the Super Destroyer Armory

Use the Armory terminal aboard the Super Destroyer, choose the weapon and select Customise. This is the route Arrowhead documents for the feature. The next gate is the selected weapon’s own progression, which is distinct from the player level that initially unlocks the menu. [1]

Steps

1. At the Armory, choose the primary weapon and open Customise to inspect its available levels and attachments. [1]

Level the individual weapon through mission use

Bring that weapon on missions to increase its individual level. Customizations and attachments unlock through those weapon levels, then are purchased with Requisition Slips. A high character level therefore does not replace the need to progress a different weapon. Arrowhead identifies objectives, missions and operations as sources of Requisitions; Super Credits instead buy Warbonds or store armor. [1] [2]

Steps

1. Use the chosen weapon on missions, return to its Customise screen after unlocking the required level and buy the desired available attachment with Requisition Slips. [1]

Understand the current preview limitation before spending

Arrowhead’s known-issues list says some attachments and their statistics do not update in the preview until they have been purchased and equipped. This explains why a preview can appear unchanged even after you have opened the correct menu. It is a documented display limitation, not a reason to assume an unsupported weapon can accept attachments or to treat every preview number as a verified final value. [3] [1]
