The Gage Mod Courier DLC is the sixth DLC for PAYDAY 2. It allows players to act as a courier for Gage the arms dealer, picking up packages containing mods that are scattered all over D.C. The DLC introduces no less than 28 new weapon modifications for the player to tinker with. 10 achievements are also added for players that enjoy achievement hunting.

Hope you have fun with that.
Good luck to all!
