Maniac Mansion
Maniac Mansion is a graphic adventure game developed by Lucasfilm Games in 1987. The player controls a group of teenage friends attempting to rescue their girlfriend from a mad scientist's mansion. Gameplay involves exploring rooms, solving puzzles, and using inventory items to progress. Players can switch between multiple characters, each with unique abilities and dialogue options. The game features point-and-click controls where players click on objects and characters to interact with them. The mansion serves as the main setting, divided into multiple interconnected rooms and floors that must be explored to uncover the scientist's plans and find escape routes. The humor and absurd characters drive much of the narrative, with a focus on trial-and-error puzzle solving and exploration rather than action-based gameplay. Different character combinations unlock alternative solutions to puzzles.
