A port of the arcade version of Ichidant-R, also known as Puzzle & Action: Ichidant-R, it is the second game in a trilogy. The game has been exclusively released in Japan across multiple platforms since its original arcade release in 1994. "Ichidant-R pushes the limits of your brain as you hunt for hidden vampires, conduct an orchestra, shoot down UFOs, and much more across 20 wildly varied mini-games that can be enjoyed locally or online! Mega Drive Mode adds in an RPG-like Quest Mode, a unique Competitive Mode designed as a board game for up to four players, and a point-based Free Mode (Note: Mega Drive Mode is presented with Japanese text only)."
