Complementing Ubisoft's cinematic Far Cry 4 presentation was a full-on gameplay demo at Sony's conference. As expected, it looks similar to Far Cry 3, but the differences in the environment--namely the more vertical nature of the Himalayan setting--made for some interesting gameplay changes. The first, and perhaps most significant, is a new grappling hook, which allows players to scale walls and swing across gaps.
Well, there's also a freaking wingsuit, which is obviously more awesome than a grappling hook. But after all the new traversal goodies were shown, the demo made a move surprising move into some co-op, which seems to be integrated into the main campaign this time around. Lastly, Sony's Adam Boyes took the stage to tease that on PS4, there'll be a way to play the game in multiplayer with friends who don't even own the game.
