There’s a few places like that in Berlin. Another one that comes to mind is Marakesch. Like where Mr. Giggles hangs out. You can pull him (or any NPC) over that brick wall. They can’t be dumped though. Anyway, you can get over to that and snap their neck or w/e.
This railing in Mendoza… Like I said, there’s no way out, and I’m 99% sure 47 can’t get into those Lavender flowers - like if he needed to get to them to snap their neck.
I ended up shooting the target.
