Online servers and four-player couch co-op
Project Zomboid supports persistent online multiplayer servers on Windows, macOS and Linux as well as local split-screen for up to four players. The developer's Build 42 server changes support configuring high player counts, but a server's practical capacity depends on hardware, mods and server configuration.
