Death Stranding may not be everyone's cup of tea, but there's no denying that it is a unique concept, powered by a strong vision that has been there since before development even began, according to new documents shared online.

Hideo Kojima himself shared some Death Stranding pre-production documents that helped Kojima Productions create the game. Most of the game's central mechanics and ideas were in place before actual work began, showing how Kojima's vision for its first game outside of the Metal Gear series was always solid.
