Instructions
Get some easy money with the code "John D. Rockefeller." You will score an easy $10,000 for your budget.
Increase guests' happiness with the code "Melanie Warn." Happier guests tend to stay in the park longer and spend more money.
Boost rider participation with the codes "Sam Denney" and "Jon Roach." The former will cause all guests to ride all of the roller coasters in the park, while the latter will make guests ride all of the non-roller coasters in the park before they leave.
Help your coaster building efforts with the code "David Braben." This will allow you to build coasters and other thrill rides with no limits on launch and chain-lift speeds. If you use the code "John Wardley," your rides will have no restrictions on height, allowing the small children to ride them.
Prevent rides from breaking down with the code "Frontier." This will save on those maintenance and repair costs.
Make the explosions bigger with the code "Atomic." While this won't help your park's profitability, it can add some fun to the game. When there is an accident and roller coasters crash, the carnage will be much bigger with this cheat.
