Background:
Get ready for an entirely new RollerCoaster Tycoon experience… it's wet, wild and totally soaked! For the first time, run your own water park — and ride all the rides — with this expansion to the smash hit RollerCoaster Tycoon 3. Celebrate summer as hundreds of peeps (that's RollerCoaster Tycoon talk for "guests") catch rays and waves with an amazing lineup of super-splash flume rides, massive water slides, aquatic shows, beaches and more. Blast peeps with water cannons, build them outrageous coasters, and wow 'em with laser light water shows!

Gameplay:
RollerCoaster Tycoon® 3: Soaked! offers players more than 50 new rides and coasters, many of which are built around a water park theme, including swimming pool complexes, massive water slides, wave pools and amazing interactivity with water, including stirring up swimming pools, firing water cannons at park guests and a brand new interactive water-based coaster called The Roller Soaker! New Swimming Pool and Waterfall Designers enable players to add hundreds of enhancements and the RCT3 MixMaster has been expanded to allow players to customize dazzling laser light, firework and water shows using the player’s own music library.
