To quote the author, Bill Kendrick's homepage, 

"X-Bomber is a multiplayer game for Unix running the X-Window system. 
It's based on "Super Bomberman" for the Super Nintendo home game system (which 
is based on "Atomic Bomberman" by InterPlay and "Bomberman" by Hudsonsoft.) 
For a great starting point on the "real" Super Bomberman, check out 
Tony Hsieh's Super Bomberman page."
