Viper V16

Viper V16 is an eroge released in 2002 for the PC by the now defunct Sogna. It consists of two separate titles: "Rise" and "Imagine".

Story
Three Anna Miller's waitresses (Akira, Saki and Karin) are kidnapped and imprisoned by a mysterious race of subterranean men—and their leader, Seed—who seek to use the girls for reproduction. Akira reveals—much to her friends' chagrin—that she is a martial arts expert, but was at first too afraid to do anything. Using Akira's skills, the trio escapes and attempt to navigate an underground maze in order to reach the surface world. One wrong move though and the girls will face a lifetime of sexual exploitation.

Endings
There are eight possible endings to the game, depending on the player's actions as they control Akira and battle the subterranean creatures and, finally, Seed himself. The possible endings are listed below:


 * 1) Akira is molested by a guard.
 * 2) A blue guard rapes Akira.
 * 3) A green guard rapes Akira.
 * 4) Akira admits her inferior power and becomes Seed's sex slave.
 * 5) Saki and Karin are captured and raped, while Akira fights Seed. If the player loses, ending #4 occurs. If the player wins, Akira is raped by a mind-controlled Saki and Karin, then by Seed.
 * 6) The girls escape from their cell. Akira battles a guard, but Saki is captured by another guard. Akira defeats the guard and finds Seed, who is having intercourse with Saki. A battle ensues. If the player wins, Saki decides to stay with Seed and the game ends with Saki having a cute baby and becoming queen of the subterranean race. This ending is the "true ending".
 * 7) Akira fights Seed. He demands that she let him rape her; Karin volunteers, however, and the game ends with her getting raped.
 * 8) This ending is almost the same as ending #6; however, if you win, Saki decides to join Seed. There aren't sex scenes in this ending.

Sequel
The storyline of Rise is continued in a later Sogna game, Viper GTB: Rise After.

Imagine
In Imagine, the main character is a student in a two-year vocational school. He goes to school and encounters three lovely girls, each in a different room. One girl yearns to become a voice actress, another is majoring in music, and the third is unsure of what future she seeks. Depending on the choices the player makes in this story, he can hook up with any or all of the three girls.
