The fourth title in the V series, VIPER-V12 presented three more new stories, the Dirty Pair parody Angel Dust, and two games that spun off sequels: Magical Gambler ToToCaL Cyomi, which spawned VIPER-BTR, and Future Investigator Bravan, which led to VIPER-F50.

The PC98 and FM-TOWNS versions include a number of promotional flyers and a packet of Official VIPER Tissues. The Windows version doubles as a Kodak Picture CD. All versions include a sixteen page instruction manual.
