Weapon Attachments are an integral part of increasing the power of your weapons in Once Human.
Each weapon attachment has certain stats that will help your gun be more Accurate, have higher effective Range or faster Reload Speed. Every weapon attachment lands within one of the three tiers of rarity – Perfect, Excellent and Fine, but for simplicity, we have categorized these into Gold, Purple and Blue attachments. This page includes all 60 Weapon Attachment puzzles and for the completionists out there – feel free to use the linked Guide Videos and Map Pins to collect all of them!
For those new to the Weapon Attachments system in Once Human, bellow are some quick tips on how to target specific attachments that will be useful to you on your leveling journey and beyond.
Best way to find the Weapon Attachment you need
The easiest way to understand which attachments will work and benefit your chosen gun, right-click the gun in your Gear menu, go to the ACCESSORY tab and click each accessory slot to see which attachment can be unlocked for your specific weapon. On this screen you can hover your mouse over the locked attachments to see what Stats they improve – this should help you decide which attachments to target first!

Once you have decided which attachments to go for, refer to the complete list of the Weapon Attachments below and use the linked videos and interactive map locations to help you with your search.
Happy hunting!

The Puzzles to unlock Gold Weapon Attachments are mostly found in the highest-level areas, such as Red Sands and Blackheart Region. These attachments are usually the best choices for your preferred gun, however we suggest looking at the stats they provide very closely before committing to a certain attachment. Some scopes also differ significantly and it often comes down to the matter of preference.
