Dark Dungeon is a wonderful name - so wonderful that there are various games bearing it - sometimes to my chagrin, as they are confused with my own Dark Dungeon. Still, most are good games in their own right, and this site is dedicated to Dark Dungeon in many forms, so... here's another one!
This Dark Dungeon is a fairly recent Flash implementation of the game you might know as "Rogue" or "Hack!" which used to be played on Unix mainframes in the 1980's. Actually it's nice, and plays smoothly. Enjoy.
