For @Xbox and @PS4 players who bought a RETAIL copy of the game: your free Definitive Edition might not unlock. We’ve only just discovered this and apologize to any users affected. Rest assured, we are currently working on finding a solution.
If you are unable to get your upgrade please contact Koch Media via the support page here: https://support.kochmedia.com/us/games/outward
Turns out giving stuff away free was more complicated that we expected. It's frustrating for us, but I can only imagine how much more frustrating it must be for you who have been affected. We ask only for some patience while we figure it out.
