Summary

The second entry in Sogna's long-running Viper franchise, Viper V-8 has the same format as its predecessor: three separate short stories with minimal interaction and animated sex scenes. The three stories are: 1. "Friday the 18th": Obviously, a parody on horror movies, telling the story of four young girls who were sexually assaulted by mysterious masked men when camping near a forest. 2. "Demon's Night" is set in medieval times and describes a battle of three young heroes against a vicious demon. One of them is seriously injured in battle, while the other (a girl) is captured by the demon; the remaining warrior, a young man named Ryu, has to rescue his friend. 3. "Alien War" takes place in the future. A young space pilot named Sylvie is captured by aliens of the enemy camp. [Edited from Moby Games]
