The original Black Ops was sorta a let down to me, it slowed down sometimes, the zombies mode though fun was pretty basic (though John Kennedy teaming up with Castro to kill zombies is badass), the lightning is sorta off and the brainwashing thing kinda bugged me.
But god, is this sequel good, possibly one of the best CODs I've ever played, and they even got Robert Downey Jr to do the TV Ad.
And about Batman, stick with Asylum.
