Don't Expect Progress to Carry Over
If you were hoping for your progress in the Uncharted 4 multiplayer beta to carry over to the final version of the game, it's time to temper those expectations.
Naughty Dog says that you won't be able to transfer your data to the final version of the game. Allowing gamers to do this would offer an unfair advantage over those who chose not to order the Nathan Drake Collection.
When the final version of the game arrives, you'll start from scratch.
