Summary
Uploading a single-player world to a Project Zomboid server allows players to experience the game in a multiplayer setting with friends or other players, adding a new layer of social interaction and gameplay possibilities. Players can work together to survive, build a base, and explore the world, creating a sense of community and teamwork. Additionally, uploading a single-player world to a server can save players time and effort. They can use their existing base and progress in multiplayer rather than starting from scratch.
