Monkey Island 2: LeChuck's Revenge is an adventure game developed and published by LucasArts in 1991. It was the second game of the Monkey Island series, following The Secret of Monkey Island, and the sixth LucasArts game to use the SCUMM engine. It was the first game to use the iMUSE sound system.
The game's story centers on the wannabe pirate Guybrush Threepwood. After defeating ghost pirate LeChuck in The Secret of Monkey Island, little is known of what happened between Guybrush Threepwood and Elaine Marley. The sequel involves Guybrush's attempts to both find the mysterious treasure, Big Whoop, and win back Elaine's love.
The development team for the game was largely the same as for the first game in the series. The project was led by Ron Gilbert, and he was once more joined by Tim Schafer and Dave Grossman. LeChuck's Revenge is considered by critics to be among the best of LucasArts' adventure games. Despite its popularity, its ambiguous and surrealistic ending drew criticism.
LeChuck's Revenge plays like most SCUMM-based point-and-click adventure games. Actions and dialogues are depicted on an Animation Window which covers the top of the screen; verbal commands are listed in the lower left-hand corner of the screen, while Inventory items are shown as icons on the lower right-hand corner. A Sentence Line is located below the Animation Window and serves in describing the actions of the player.
The game was also the first adventure game that offered the player two levels of puzzle difficulty. In some versions, before starting the game, the player is prompted to choose between regular version and "Monkey 2 Lite", a relatively stripped-down experience that bypasses many puzzles entirely. On the back of the game's packaging it is (jokingly) stated that this mode is intended for video game reviewers.
