ahhhh. This makes so much more sense. something I didn’t consider: the phones are simply embedded into everyone’s brains before birth. The zombie “virus” is a bad software update that the mega Corp phone/media/entertainment/search engine/waffle conglomerate company pushed out to hit an advertisement deadline for a new movie.
And.. all the zeds in this area *are* the advertisement for this new movie premiere, and they simply sacrificed all these people (they’re aware, but being remotely controlled against their will) to act out the advertisement. You were air dropped in with the phone camera in your skull as part of the. “You’re really in the movie as the survivor” clips they want to show everyone else. That’s why when you die it’s like “oh well, we dropped in another one who knows exactly where all their stuff is” by using augmented reality to overlay the backpack, home, etc.
anyway, that’s were all the phones went. Simple explanations are always the best.
