Lost Expeditions is offering "40 minutes" of extra stuff. We don't know howl long monkey business will be but it looks like more and looks pretty cool. Do we actually know any information about lost expeditions?
Monkey business has two bonus end-match humiliation options. (the cutscenes where you can choose to kill or spare)
I personally would like the Lost Expeditions pack, but I already pre-ordered the EB one (Monkey Business) and paid in full. Lost Expeditions has one new mission that interests me about escaping a lab full of "experiments". Could be awesome and like FC:IP.
