I think you misinterpret all my post. With not big I don't mean "it is maybe about an hour or 2". I just meant that it is not big, just a camapign of an Call of Duty or Battlefield, about 6 hours ~ maybe.
Wait...just how big is the single player expected to be in this? I think I may need to go on a blackout.
There are quite a lot of levels shown in this.
