Just saying - could you do "Infinite Money" or option similiar to that on Survival mode? It would be useful.
And - there is nothing to do about different "realm" in Spec Ops? I mean - your teammate sees something else, and you see something else too.
Forgot to add - Infinite Turrets and equipment (such as, infinite AC or Predators, squads) would be great.
I hope you will made those options, of course - i know that some of them will be haard.
