One of the first games in a long while, that has kept me up until 5 A.M. in the morning, because of how lost I get myself into it.
Parkour in the game is AMAZING. Sometimes I like just playing the game, so I can run
around, across roof tops, and attacking zombies while talking to friends.
Co-op in story mode. Freaking amazing. No dumb lobby. Just click 'Join game' and bam,
you'll be thrown a few feet away from a friend without them sometimes even noticing you joined!
