No new content?
Hookblade and ziplines, bomb crafting, Den defense, Master Assassin missions, Animus Island and Desmonds Journey, and the graphics are slightly sharper. (no more dancing shadows!)
I suppose compared to the previous AC's it adds less, but there is way too much content for it to be a DLC.
But really, AC revelations is the final chapter in Ezio's story. It was more of a "tying up loose ends" part.
this exactly! game has ALOT of new stuff over AC2 and really brings more into play than ACB did. you have to remember this is not AC3 but an expansion on this part of the game.
