Upgrade any weapons by enhancing their blueprints in Once Human. Read on and learn how to upgrade weapons, other weapon upgrade methods to increase their damage output and performance, and how to get blueprint fragments for your blueprint enhancements!

How to Upgrade Weapons

Enhance Blueprints

Upgrade your weapons to increase their damage across different tiers by enhancing their blueprints, which is done via the Blueprints tab. Enhancing a weapon's blueprint requires XP, which can be acquired from blueprint fragments.

Once a blueprint has been enhanced, it will increase its rank (denoted by the stars on the top right), and you'll be able to craft the related weapon with increased stats. Existing copies of the weapon prior to enhancing its blueprint will not be affected with the stat increase.

Blueprint Fragment XP Yields

The amount of XP depends on the fragment's rarity. Using the weapon's own blueprint fragments will yield double XP.

Types of Blueprint Fragments Styles

All weapon blueprints have different styles of Blueprint Fragments: Hunstman, Wanderer, Operator, Juggernaut, Beyonder, and Stranger. Enhancing a weapon's blueprint using other weapon's blueprint fragments can only be done with the same blueprint fragment style as the blueprint being enhanced.

Calibrate Weapons

Calibrating a weapon will increase its DMG stat per calibration level at the cost of materials and Energy Links, which is done via the Gear Workbench. Reaching calibration levels 4, 7, and 10 will activate an additional calibration attribute, which are basically random stats to improve your weapon's performance.

Calibration does not affect other copies of the same weapon, and the stat increase only affects that particular weapon that you've calibrated.

How to Get Blueprint Fragments

Wish Machine

Blueprint fragments can be acquired via the Wish Machine. Spend Starchrom for a chance to obtain the weapons' blueprints themselves, or blueprint fragments, which can be fused to create the blueprint.

How to Get and Use the Wish Machine

Opening Mystical Crates

Mystical Crates contain both weapon and armor blueprint fragments. Go to key locations in an area to find the Mystical Crates hidden within. So far, only one Mystical Crate can be found per location.
