Tengai Makyō: Deden no Den (JP: 天外魔境 電々の伝), or simply Deden no Den, was a promotional demo version of Bomberman '94 based on the Far East of Eden RPG series. It was released for the PC Engine console in 1993.
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.
The game is very much identical to Bomberman '94 Special Version, but features the character Kabuki in place of the typical Bombermen.
