1. The Story and The Characters
Black Ops 2's single player story mode is written by The Dark Knight trilogy writer David S. Goyer so we can no doubt expect a step up in story from previous entries, even the first Black Ops game. The new setting could provide a new inspiration for the story. Also, Treyarch has employed a new facial animation system and it looks awesome. Check out the E3 gameplay
to see an example of this. I love how Treyarch constantly finds more things to do, as opposed to Infinity Ward's..."innovation". And kudos for the protagonist a voice, it's a shame it's so ignored by all modern shooters. Also, a quick note, the pilot Mason is communicating with sounds like Jennifer Hale. Anyone agree?
