Ubisoft has so far only shown Far Cry 4's intro. This, though, this is seven minutes of gameplay that has turned up a little earlier than expected (and not from Ubisoft's official channel). Catch it before it's gone! [Update: it's gone, but we've got gifs]
I'm a little suspicious of just how "real" this gameplay is - the transitions are too smooth for my liking - but still. More wingsuits and elephants and all that co-op stuff is good stuff.
UPDATE - In case the vid gets pulled again, here are some gifs.
