How to unlock the Days Gone secret ending

The Days Gone secret ending takes a fair bit of effort to unlock but reveals a big twist that sets up a Days Gone sequel - which is a shame because Days Gone 2 is almost certainly never going to happen now. Seeing this secret ending requires you to finish almost everything there is to do in Days Gone first. That includes, clearing out all Freaker hordes, Ambush Camps, and collecting all the IPCA tech and more. If you've rolled the credits but still want to round off the story with this Days Gone secret ending, here's what you need to do to unlock it.

Obviously there are massive Days Gone spoilers below so you've been warned!

Days Gone secret ending explained

Okay, after you’ve seen off the crazy militia, fought the final battle and watched the credits roll you’ll be put back in the world to roam around finishing up loose ends. To trigger the secret ending you’ll just have to keep busy for a little while until the NERO scientist O’Brian messages you to meet up (fast travelling and completing side missions might speed things up here). After he calls, you'll start a mission called ‘There’s Nothing You Can Do’ which begins at the Old Pioneer Cemetery. Head over there, talk to O’Brian and prepare for the mother of all bombshells...

Once that’s all played out you’ll unlock the crafting recipe for a secret weapon that uses all that Days Gone IPCA Tech you've been collecting, and a custom Finding NERO design to add to the Days Gone skins for your bike. You’ll also see a percentage completion but don’t sweat it if doesn’t hit 100% because it’s tied into other activities you’ve completed in the world.
