A new trailer for next week’s PS4 slasher horror Until Dawn has been released which focuses on the Butterfly Effect.

Decisions players make will impact events in the game to such a degree that there are thousands of paths, with some story branches more complex than others.

“We’re estimating that, for most players, people will see less than half of the content included on the disc the first time that they play it. What’s more, we’re pretty confident that everyone’s experience of it will be slightly different,” explained SCEE product manager Tim Hodges.
