     Sogna combined the best of both worlds in VIPER-M1: a modern, Windows-based interface and a set of three smaller games, reminiscent of the earlier V series titles. Super-heroine story My Mothers features cover girl Mika in her attempt to rescue a prospective boyfriend. Coming of age tale Green Boy follows Natane and her two older sisters as they welcome a strange young man into their home. The May Works focuses on a schoolgirl, Maki, as she flees from an alien invasion of her hometown. Game package includes sixteen page manual, VIPER-F40 Novel Edition and COSPA VIPER series clothing advertisements, nine Sogna Official Trading Cards (numbers 73 through 82), and a mail-in card for a chance to win a gold foil teleca in Sogna's one and only "Gold Teleca Present Campaign."
