Those issues can undoubtedly be fixed by a patch somewhere down the road, but that patch seems unlikely to fix Unity's biggest flaw: it's just not very much fun. For all its hugeness and graphical splendor, Unity is starved for excitement. It's much too concerned with a story that feels confused by itself, wasting potentially interesting allies and antagonists in much the same way that it wastes the rich, violent history of its time period. The most interesting missions in the game come far too late, representing glimpses of a better game than the one you just spent hours playing. Even as a tech demonstration, Unity fails to captivate outside of its stunning art design. It's less a signal of the great things this series can do with new technology than an unusually large, frequently malfunctioning retread of what Assassin's Creed is already well known for. Co-op play is the sole saving grace of Unity, the only aspect of the game that feels reasonably complete, but that co-op alone isn't enough to make up for the myriad other ways in which Unity is deeply, disappointingly deficient.
