There are a lot of incredible minor details in Kingdom Come: Deliverance 2. The game's recreation of the Kingdom of Bohemia in the early 1400s is remarkably accurate to the period, prompting an investigation by one player into a specific part of Kuttenberg – how does the town's main fountain work?
This is actually suggested in the game by Henry. "A fountain? Where does the water come from? Here in the middle of the city," he asks when you walk up to the aquatic installation. YouTuber Any Austin took this as a challenge to find out, since it's implied there's some form of solid conclusion somewhere nearby.
