Rollercoaster Tycoon 3: Wild is the second official expansion pack for Rollercoaster Tycoon 3. This expansion allows the player to create animal enclosures and safaris, as well as many new ride types and rollercoasters. The expansion was developed by Frontier Developments, who created the base game and the first expansion: Soaked!. The expansion was released on November 4, 2005 - just a year after the original game. Chris Sawyer again oversaw the development but otherwise had no hand in the games final design.
The gameplay builds upon the foundation set by Rollercoaster Tycoon 3. A new career path offers 12 new levels for the player to progress through. The major addition of animals allows new gameplay opportunities, such as hiring game keepers and providing guests with animal shows and safaris.
