StarRupture has a fairly wide set of weapons that you can unlock, and all of them can be upgraded with the use of various mods.

While modding is relatively simple, you’ll first ned to unlock the mods. Each weapon has its own set of attachments that you unlock as you play more. This guide has all the required information needed for you to modify all your weapons.

How to mod weapons in StarRupture

You can start adding mods to your weapons after you unlock the Equipment Upgrade Station. To do so, you’ll have to raise your reputation level with the Griffiths Blue Corp to four.

  • Craft the supply lines for Titanium and Wolfram.
  • Build a Fabricator and a Smelter.
  • Obtain the Titanium Sheet and or Wolfram Plate recipes (any one works).
  • Complete the recipe, set a commission for it with the Orbital Launch Station, and send it to Griffiths Blue Corp.

Claim the Level 4 rewards, and add 120 Basic Building Materials. This will allow you to create the Equipment Upgrade Station. You can then use the Equipment Upgrade Station for unlocking weapons, mods, and adding the latter to your guns.
