Through our playthrough of the game, we were able to discover that the above-mentioned code is used to unlock content that is already on the disc. The bonus chapter blends in with the rest of the story near the beginning portions of the game. You can read more about the scenario, which has some slight spoilers, below.
The extra chapter covers Matt and Emily retrieving a lost luggage as they tread through the snowy mountain path. If you entered the code to unlock the bonus chapter, you will be able to play this scenario. If you don’t have the code, you would skip ahead to the next chapter. If you enter the code but already got past that point of the story, you should be able to check out the chapter after beating the game for the first time.
Until Dawn came out exclusively for the PlayStation 4 console on the 25th of August in the North America region. The survival-horror adventure game has become a sleeper hit, especially for fans of the genre and horror films.
