Tengai Makyō: Deden no Den is a promotional game based on Bomberman'94 and mixes Hudson Soft's classic Bomberman with Red's immensely popular role playing game Tengai Makyō (aka Far East of Eden). This game offers the Battle Mode from Bomberman'94, and replaces the traditional Bombermen characters with the blue-haired Kabuki Danjurou, the eccentric Kabuki performer and swordsman. However, this promotional game only features one battle arena (a code can unlock more playfields though) and is multi-player only (no CPU players).
It was distributed exclusively at the Super Caravan events in the Summer of 1993 as a participation prize for the Hi-Ten Bomberman competitions held there. While an accurate number cannot be confirmed, it is estimated that around 20,000 copies were produced.
