This morning at the PlayStation Experience Keynote, the first ever demo for Uncharted 4: A Thief's End was shown off. The nearly 10 minutes of gameplay featured Nathan quietly overlooking a cliff in the early hours of the morning (good timing, as it also shows us the water effects before heading into a cave. He then does more exploring and comes across artifacts and even a dead body. Of course, he soon finds himself embroiled in gun battle -- but this time the action moves to a series of cliffs. Unfortunately, it there was a pretty nasty glitch that followed this, but it seems simply a case of a game not being fully completed more than a bug with the final version itself.

Perhaps most excitingly, a new character -- Drake's brother -- was introduced.
