Description:
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.
