Mod 50 Weapons
You can modify weapons at weapon workbenches in the game. To unlock this achievement, make a total of 50 modifications to weapons throughout your campaign.
You can monitor your progress in the status menu under the "Crafting" tab.
Weapons in the game can be modified at Weapon Workbenches, with one available in the basement of the Lodge, where you first meet the Constellation faction (found in the Alpha Centauri system, on the planet Jemison at the Landing Site, The Lodge).
Upon entering the building, turn right and proceed downstairs to the basement where the Weapon Workbench is located.
To modify weapon parts, ensure you have the necessary materials and research level.
To monitor your progress, navigate to Menu > Status > Crafting > Weapon Mods Crafted / Armor Mods Crafted
in the game. This menu allows you to see the number and type of weapon and armor mods you have crafted throughout your gameplay.
