How to bypass 'you don't have the required content' - Dying light
Must be done on HARD or NIGHTMARE difficulty, but can also be done on lower difficulty settings if playing with friends or random people.
Just a short video on an issue I had with some of the weapons given to me via people joining my lobby.
This can happen to the:
Volkan set of weapons except the pistol for some reason.
Marksman rifle
Volatile hunter knife
Grim sceptor
and other DLC and additional content weapons.
