in Duke Nukem 3d, disturbing was the site of naked women held in green cocoons. only to say kill me and make a horrific scream after being killed.
in Episode 1 they never spawned but Episode 2 and beyond they spawned those octopus creatures.
in Episode 2 they were held tied to those green columns and tied down on green stuff.
was the purpose to arouse the player? hardly sexual if they are captive. more like sexual offence.
