Leisure Suit Larry 6: Shape Up or Slip Out! is the fifth entry in the Leisure Suit Larry series of graphical adventure games published by Sierra Entertainment. Originally developed for DOS, a remake was produced in CD-ROM format a year after its release. The enhanced version of the game offers revamped graphics in SVGA resolution and voice acting, a first for the series. Both versions use an icon interface similar to other Sierra games of the time, but unlike most Sierra games, the icon bar is visible at all times.
The plot continues the exploits of series protagonist Larry Laffer, who has won a free trip to a luxurious health spa populated by women. Unlike the previous game, it is again possible for Larry to die in various ways, though the series' traditional black humor is toned down.
Larry Laffer is once again single at the outset of the game, as his girlfriend Passionate Patti has been retconned out of the series. After competing—and losing—on the television dating show Stallions, Larry wins an all-expenses paid trip to La Costa Lotta, a refined health spa. Due to his status as non-paying guest, he is treated rudely by the staff and given the worst room on the premises. As such, none of the available women in the resort want anything to do with Larry, though it is possible to change their minds with the right gifts.
The eight romantic interests, all of whom are named after types of wine, include Gammie Boysulay, a receptionist whose svelte upper body conceals an enormous lower half; Rosé Eleeta, a Spanish beauty; Thunderbird, a female weightlifter; Charlotte Donay, who spends most of her time in a mud bath; Burgundy, a country music singer who performs at a blues bar; Cavaricchi Vuarnet, a bisexual aerobics instructor; Shablee, a makeup artist (ultimately revealed to be a trans woman); and Shamara Payne, a depressed New Age follower. Shamara is Larry's ultimate goal in the game; his encounters with the others will only result in Larry's humiliation in one form or another, though he will always gain something necessary to win over Shamara.
Larry encounters several romantic interests within the hotel, various means to entice them into a tryst are laid out until all the women, but the final one Larry meets have rejected him in one form or another (in one case, however, Larry does reject a prospect as well):
Gammie – the beautiful receptionist of the La Costa Lotta. She expresses disinterest in her hips and wants access to the liposuction room.
Merrily – the pool bartender whose one passion is death-defying stunts such as bungie jumping.
