Can this mod upgrade rocket launchers and Tek gear?
Rocket launchers can't be upgraded anymore. Wildcard has removed the Initial Value Constant from them which, because anything multiplied by zero equals zero, means that sadly the stats simply can't be increased. (We have some ideas around that, though.) Tek gear can be upgraded but they don't show colored quality levels (yet).

^ Adds the old Rocket launchers back to the game and can be upgraded with the upgrade station :D Surpised the mod creator never updated that description for this mod to include that. Oh well, enjoy bud!
