Looks like Sony kept something pretty amazing away from us.

For reasons best known to Sony, the best thing at E3 was the longer version of its E3 Uncharted 4 demo that it didn't show at the conference. Behind closed doors, an extended version of the truck chase continued the sequence and raised the bar so high it might well break all other games.
What happens is impossible to describe without falling into hyperbole because holy Christ I nearly lost my shit, with gameplay that almost seemed to be mocking your ability to deal with it - piling sequence onto sequence, and building the pace and action up to to a level that's almost impossible to comprehend without seeing it. Nothing else out there can compete with what I saw: there's honestly a world before that demo and world after.
