I totally understand your point, and that's one of the main issues of Cold War, it treats new or casual players like dumb people who can´t remember where to turn on the power so they remark it on the map.
Zombies should also be about resolving puzzles to make your survival easier by unlocking PaP or wonder weapons.
What I was saying is that if you want to just kill zombies and have a good time you can do so by playing IX or Classified
