Secret Ending & Secret Weapon

Unlocking the secret ending and secret weapon in Days Gone.

To view the secret ending, first complete the main story. After finishing the final mission and watching the credits, you return to the open world. Keep playing by doing remaining side missions, capturing NERO Research Sites and burning Freak Nests. After enough time passes, O'Brian contacts you over the radio to start the true final mission, 'There's Nothing You Can Do,' at the Old Pioneer Cemetery. Meet him for a huge revelation. Completing this final mission earns you a craftable secret NERO weapon that uses ICPA Tech.
