So looks like this may be more than just a port from the ps3 editiion, new content being added for the PS4 edition:
-Of course it includes the original full campaign mode from the PS3 edition, but also includes the DLC for Road to Devastation that adds two game modes (arcade mode and endless mode)
-New to PS4 edition is challenge mode allowing players to post scores to freinds, allow players to play with their freinds avatars to try and beat their record scores and compete against challenges posted by people on the leaderboards
-Now the coolest new feature IMO is Broadcast mode. When a player streams their gameplay, viewers can affect the streamers game through voting to input certain conditions like spawning ammo or disabling sprinting among others im sure.
Also in 1080p for anyone thats curious
So whose getting this on Tuesday? And what do you think of this game and its new features?
