AusGamers has previewed Assassin's Creed 2 and writes:
"In all, this painted a picture of Ubi maintaining the strongest elements of the first game, while removing repetition in place of a variety of elements such as a more dynamic crowd system, different levels of guard reactions, curiosity and alarm, as well as all-new gadgets and ways in which to approach the game-world overall - demonstrated in finality as our demo ended with Ponbriand escaping more guards chasing him by diving - tantalisingly - into a Venice water canal, sans the game's new swimming system (apparently we'll be waiting for that)."
