Dear Bethesda,
I have been playing your fallout shelter mobile game and stumbled upon an idea. Having played all of the previous fallout games, I possess a massive amount of appreciation with the direction you have taken with the franchise. This content idea would likely present itself in a $10-20 DLC package with an optional story based around the largest vault ever discovered. The main draw to this new content would be that at some point the player would be given the option to explore "The Endless Vault." Each new floor is randomly generated with various loot, baddies, and floor design. This never ending vault crawl could blow people's minds. Looking at the stacks of floors and elevators in fallout shelter gave me the idea. There could be additional twists to how this system works like maybe even giving the player control to choose what enemies would be found within each new floor of this endless adventure. Your company is famous for taking good ideas and pushing the innovation even further. If you receive this idea and make it into something beyond expectation I would not be surprised. Thank you for all the enjoyment of the past and future days to come.
Sincerly,
Lifetime Fallout & Bethesda fan
