Super 8 Interactive Teaser

Portal 2 video game contains an interesting extra feature that allows "players" to briefly interact inside the train car that is seen crashing in the trailers up to the point that the creature escape. The video below shows off this teaser but from what I can tell no real secrets are revealed. It is mostly just an interesting way to promote a movie. Knowing Abrams, the codes on the documents probably work in whatever online viral-marketing campaign that goes with the movie but so far I have not found any details.
