There is a zoo in the activity montage and I have not seen anyone talk about it.
A zoo is a strange thing to build. It is a pedestrian area full of animals with their own behaviour, which is expensive, and it is not obviously a place you do crime. So either it is a small area with a few enclosures, or somebody had a very specific idea. Does anyone know which?
Nothing beyond its presence in the montage. It is on screen briefly and no interaction is shown.
there is a real one down here that is basically a zoo built into a swamp and if they did that version it is going to be incredible
I had not thought of it as a place a mission happens at all and now I cannot think of it as anything else.
A zoo would also be a cheap way to have exotic animals in a game where the wild ones are regionally limited. That might be the actual design reason.
A zoo is also the single most obvious place for something to go badly wrong in a story mission and I refuse to elaborate.
