Scooby-Doo Mystery was released by Acclaim in 1995 based on the Scooby-Doo animated series. The Sega Mega Drive version is a traditional adventure game with a point-and-click-style interface. Players take control of Shaggy Rogers and Scooby-Doo, who help solve various mysteries with other members of Mystery Incorporated who serve minor roles during gameplay.
The game was divided into two scenarios: “Blake’s Hotel” and “Ha Ha Carnival”. The player controls Norville “Shaggy” Rogers, who is followed around by Scooby, while Fred, Daphne and Velma make brief appearances in, often at the beginning and end of a mystery. The object of the game is to solve puzzles to progress, uncover the mystery and catch the monster/criminal to win the scenario. The player has ten different commands located at the bottom of the screen to control Shaggy and solve puzzles. The action menu can be switched to the inventory menu to interact with the items and put them to use. Most of the puzzles require logic to solve, while others require a specific action to solve.
In the first scenario, the gang goes to Daphne’s Uncle Blake’s hotel where a ghost of a Native American Chieftain has been scaring away clients and staff, with only the gardener and the cook remaining. While the gang goes to investigate, Shaggy and Scooby go inside the hotel only to find Blake has been kidnapped. Eventually Shaggy and Scooby come across a gold mine under the hotel and the heart of the mystery is revealed to be an ancient medallion the ghost is looking for.
In the second scenario, the gang goes to the Ha Ha Carnival which happens to be closed. An evil clown has sabotaged the services and imprisoned the carnival manager. Shaggy and Scooby help the manager and rescue the others stranded in a lake. After trying out all the rides, Shaggy and Scooby find out that the clown has a prime interest in getting employment in the carnival but was immediately rejected by the manager and proceed to capture him.
