Currently there are no plans for Until Dawn DLC, but if Supermassive does revisit the game in an expansion, context would be everything.
In an upcoming interview with PlayStation LifeStyle, executive producer Pete Samuels was asked whether we'd see any DLC for Unil Dawn any time soon.
"The underlying ‘truths’ in the story are pretty sacred. If an expansion of any kind required us to change a truth then we wouldn’t be happy doing it," he explained.
"We get asked a lot for a happy-ending for one character in particular. We can’t see how that could work without breaking some important truths. I’m not ruling out DLC, we just haven’t yet found the right context for it."
If you've already completed the game, let us know how you think any DLC might work with the story - if at all.
