According to Kojima, one of the key aspects of the announcement trailer was the idea of a connection between life and death.
Kojima compared the main "tools" in action games – punching, shooting and kicking – to sticks, and said that in Death Stranding he wants people to communicate through the game equivalent of ropes. Kojima described its genre as a quasi-action game, but with new and different elements.
Kojima explained one of the game's main themes through a short story by Kōbō Abe, in which Abe says that the first tool created by humans was a stick, meant as protection by putting a distance between oneself and "bad things", and that the second tool was a rope, which is used to secure things one finds important.
