Sandbox Mode is a cheat that enables many features from the Scenario Editor to be used in a regular game. These features include:

• Editing land ownership
• Editing park entrances
• Editing peep spawn points
• Editing map size
• Editing land and scenery outside park boundary
• Access to restricted objects, such as road footpaths and restricted scenery in RCT1 scenarios

Park entrances may be changed, but care must be taken not to orphan in-park peeps when changing the land, or not to let out-park peeps into the park area. This is not in their programming and will glitch the peeps.
