I never thought I would try to go for the Dark Matter skin for all of my weapons. I finally gave in and decided to start with getting seven SMG gold skins.

This entails getting a hundred headshots with each SMG. Once you reach the hundred headshots, you must get x kills without dying. Then you can unlock the next tier, which is the diamond skin. Once you accomplish this, you can go for Dark Spine and then Dark Matter. It’s a lot to grind out, and it becomes kinda repetitive and boring, but it’s another goal to accomplish. It’s definitely not for everyone.
