Bethesda’s first ever E3 press conference came with one honest surprise. Everything else was good to see, but expected: Dishonored 2, Fallout 4 (even with the 2015) release date, Doom and Elder Scrolls Online: all cool, but no true surprises. Right in the middle of the Fallout announcement, however, Todd Howard dropped something new that nobody saw coming: Fallout Shelter, a free-to-play game about managing a wasteland vault. It’s a bit like a apocalyptic Tiny Tower. And I just can’t seem to stop playing Fallout Shelter.
