The pitch as I understand it;
There are ghosts, when ghosts touch dead bodies they explode. America is in semi-apocalypse mode because of said ghost explosions. You play as a man who can put his ghost back in his body without exploding, so you are the deliveryman between the sparse enclaves across America. You will travel from point to point while keeping your cargo intact, avoiding ghosts and raiders, and building travel infrastructure like ziplines and roads. You can also download the infrastructure from other players and maintain it by “liking” it. It’s a hiking simulator with themes of American paranoia, digital social spaces, and parenthood.
Oh, you also carry a baby born from a corpse. The baby let’s you see exploding ghosts.
