Waterpark Simulator Multiplayer Guide
Version 1.0 supports online co-op for 2β4 players on Steam, PS5 and Xbox Series X|S.

Host a lobby, invite up to three other players and split the park into clear responsibilities. One person can handle tickets and money, another cleaning and repairs, while the others build or respond to events. Co-op is included with the standard game.
What to do
The host should review permissions at the ticket-booth computer before opening. Current patches add controls for throwing/PvP, Caymart purchases and painting, plus lobby bans. Give new players a simple area and tool set first; patch 1.0.30 also made the hammer a starting item for joining players.
What the sources support
Official store pages confirm single-player and 2β4 online co-op on the three announced platforms. Patches 1.0.43 and 1.0.48 added more host controls, a Saboteur option, placement rate limiting and Steam ID anti-spoof protections.
Version notes and limits
Host settings are still evolving quickly. Check the lobby and ticket-booth menus in your current build before assuming an older video shows every option.
