A small theory I have in my head right now, has to do with the possibility
of our group of survivors having short term memory loss. If you listen to the TV easter egg,
the CDC scientist speaks about some of the symptoms of people with the infection.
And one of those symptoms is short term memory loss. Now if you watch the animated opening,
at the end the team is transported back to the spawning room of Die Rise.
Samuel then asks "Have we been here before?" I'm not sure whether to take this as
sarcasm or not. However this supports other theories of Richtofen being able to bring them back to life.
Perhaps they're losing their short term memory every time he respawns them?
Remember, this is just a theory. Give me any feedback to help support or disprove this.
