Waterpark Simulator Leaves Early Access with Multiplayer, Beach Map, and Customizable Slides
After several months in development, Waterpark Simulator has reached its 1.0 release. The launch announcement, posted by author Hai Cayplay, is brief on reflection and heavy on patch notes — which is where the substance lies.
What changed
- Multiplayer mode — up to four players (the host plus three others) can run a park together from the start or load existing saves. Proximity voice chat is optional.
- Beach map — a new beachfront setting described as inspired by a neon Miami aesthetic. Existing park layouts cannot be transferred, and the map introduces sea-specific mechanics.
- Character customization — players can now define their manager's appearance and save up to five presets. Beards are absent, attributed to model issues the developers acknowledge caused significant bugs.
- Customizable slides — a freeform slide-building system, with the caveat that guests getting stuck is an acknowledged possibility.
- Museum — a new location housing three NPCs, each opening a separate quest line with its own distinct currency.
- Three new themes — Aztec, Sea, and Pirate, unlockable through a research tree funded by museum currencies. Each theme branch ends in a large slide.
- Night mode — parks can operate after dark at increased staff cost. The announcement notes cheating guests increase at night but are easier to spot via glow-in-the-dark bracelets.
- New food stand — a new food option beyond hot dogs, though the source text is cut off before naming it.
For players who have been following the game through its early period, 1.0 delivers a meaningful structural expansion — particularly the museum's quest economy and multiplayer — rather than a simple polish pass.
