Trigger

Trigger consists of three unrelated stories, all of which heavily focus on explicit sexual content. The first story depicts violent and monster-related sexual encounters of a young woman. In the second one, a female detective attempts to investigate the murder of her father and gets captured by the criminals. The third story deals with a raid of mechanized pirates on a spaceship controlled by two young girls.

The gameplay is identical in all the three stories, consisting of visual novel-like prompts (three per scene), which do not affect the plot; the player is often required to go through the same choices several times to trigger the next scene. Most of the adult scenes are animated.
