I played inFamous: Festival of Blood back to back with Assassin's Creed: Revelations, and it made me flip on a very important issue of our times. I now know, as objective truth, that inFamous has better city climbing/traversal mechanics than Assassin's Creed for one important reason: Because bats. 
 
Bats! As part of Festival of Blood you can turn into a swarm of bats and, for a limited time, fly (almost) anywhere you want in the world. Combined with the rail grinding, quick climbing, and Cole's awesome hover ability, no game is more fun to quickly cruise around the world. The only thing I was missing here is the ice jump from inFamous 2, but by and large the bats has you covered. Ezio is more or less a superhero, but Cole is more or more a superhero. The game does an amazing job of making you feel powerful. 
 
In this two or three hour stand-alone inFamous story, we have Cole's "you might be a redneck" buddy Zeke trying to pick up a hot chick in a hick bar telling her about the time Cole was almost turned totally into a vampire. Zeke's intro and narration through the game is hilarious. It's more inFamous (which is in itself awesome) where you use Cole's electric abilities along with some new vampire based abilities to solve a few puzzles, but mostly just murder fools. 
 
As a vampire, Cole can turn into a swarm of bats as breathlessly alluded to earlier, but he can also use his vampire sense to see things that mortal men cannot. This includes hidden teachings from your coven's leader, as well as which of the pedestrians around town are secretly vampire Firstborn. 
 
It also has Move support. No joke. I tried it out, and I could see it being fun, but I would have to totally retrain my meager inFamous brain. Using a full sized controller for the non-Move hand was also a bit awkward. Maybe with a sub-controller it would be better.
 
The story is good, it's more inFamous, and it's the best-in-class city traversal that the kids love. And it's $14.99. For this much fun, a bargain.
