ScreamRide is a rollercoaster construction video game. The game features four singleplayer modes: Engineer, ScreamRider, Sandbox and Demolition Expert.
Engineer is the main mode where have to build rollercoasters with a limited amount of money while also meeting certain conditions. In ScreamRider the player drives the rollercoaster itself and has to prevent people from falling off. Demolition Expert has the player modifying the environment and the ride itself so the rollercoaster cars with people in it get thrown about, destroying the landscape and buildings.
The last mode does not feature missions but is rather a sandbox mode where players can build any rollercoaster and modify the scenery.
