Leisure Suit Larry 5: Passionate Patti Does a Little Undercover Work is the fourth entry in the Leisure Suit Larry series of graphical adventure games published by Sierra On-Line. It is the first title in the series to have 256-color graphics and a fully icon-based interface. The title of the game is misleading, as there is no Leisure Suit Larry 4. It was re-released in 2017 on Steam with Windows support.
