Looking at Death Stranding on YouTube got its mysterious algorithm's attention, and a '
Before you buy Death Stranding' video popped up. I watched it and it showed a recording of the player near the starting city headed up toward the incinerator. I happen to have a video of the same area, which you go through late in the game with some great music playing, so I've seen it a few times.
When the video is playing, you can see a rope and a ladder placed by "Igor," which has less than 10 likes. Watching my video, the same rope and ladders are still there, even though it was two years later. They still had single digit likes, too!
The guy who first explains the world (slightly) to you in the truck of the opening cutscene is named Igor. Dunno if it's the same guy, but it's definitely not a player.
