Hey Guys,
First time poster long time reader, but I had to contribute what I thought was going on here..
First, we know that Der Riese means the giant, but they have it misspelled to Der Reise, meaning "the travel"...simple mistake? judging by the interview mentioned in other parts I think not. So why?
I believe the moon will take place on two levels. I think you start on the moon, but you end up back at Der Riese in various parts of the level, whether it be through teleporting or even flashbacks. I really think the story is gonna end here, and I think them going back to Der Riese will serve two purposes. First, we will be able to see how the World has changed over time with zombie infestation. Second, I think here it will tie up a lot of the loose ends in the story, thus giving us the ending we all think we need and deserve.
Why else would they purposely misspell it to mean the travel?
What better way to end the zombie story line than to go back to the beginning?
