[Vampyr]

I think this just goes to show that there wasn't enough time to build a proper campaign in Modern Warfare 3. They had to cut corners and do things like have you sitting in a passenger seat shooting a turret for the majority of the campaign. They basically turned it into a rail shooter, from what I hear.

Now, that doesn't make it an "un-game"...rail shooters are still games, but it is different, and not as fun as what we had in the past.
