So a militant Singapore group's reaction to finding out that the US/CIA was involved in a disaster there is to go on a mass killing of their own people and tearing down of infrastructure they made themselves?
Ok.....
The setup and most of the game plot is pretty

even for Call of Duty. At least it keeps that traditional Blops "lol wat" so bad it's awesome and they know it part in it though. Even if there's only like 1.5 of em after II had a whole bunch of goofy ones.
I think they focused their story efforts on the zombies mode, which makes sense. That's where all the big voice talent is too. And part of it carries plot/characters over from II. (At least according to Wikipedia, haven't played zombies and probably won't play zombies. I think I accidentally started the equivalent Ghosts version of it once.)
Main complaints I have with AW and this for single player is that they don't seem to be implementing many stupid cool parts with the new gameplay, it's kinda the same ol setpiece design still. I think Ghosts' flood is the last one I really liked.
And that's probably my obligatory one post about CoD's single player campaign.
