Death Stranding is the first game from Kojima Productions, a studio founded by legendary game developer Hideo Kojima. After a rocky departure from Konami, where he built up the Metal Gear franchise, among other projects, Kojima started his independent studio and revealed the first title would be exclusive to Sony's Playstation 4. The reveal trailer premiered during Sony's 2016 E3 conference, and sets the stage for the weirdness we're delving into.

Still confused? Don't worry. Ever since its initial announcement, Death Stranding has been shrouded in mystery. Kojima is famous for his unconventional promotional methods (at one point pretending to be part of a non-Metal Gear studio making a non-Metal Gear game) and for building strangeness into his games (see any Metal Gear ever), and Death Stranding is no exception.
