XRogue was developed by Robert Pietkivitch between 1989 and 1992 for the AT&T UNIX PC. It is based on Advanced Rogue 7.7.

XRogue includes over 200 monsters with many new capabilities, many of the monsters are intelligent and they, like the player, must avoid traps and decide when it is better to fight or to run. There are also a number of new commands in this version not found in previous versions.

The game contains monsters, spells, weapons, armor, potions, and other magical items that you will discover during your quest. The Dungeon's geography changes with every game and although many magical items have certain identifiable properties, such as turning the player invisible, the physical manifestation of the magic changes each game. A red potion, for example, will cause the same reaction throughout a given game but it may be a completely different potion in a new game.

Entering the Dungeon with only a little food, armor, and a weapon, the player must develop a good strategy of when to fight, when to run, and how to best use any magical item found in the Dungeon. To make things interesting the player has a quest to return one of several unique and magical artifacts which are rumored to lie deep within the Dungeon. Returning with this artifact to the surface brings great honor.

However, after finding the artifact, the player may wish to continue his quest deeper into the Dungeon to match wits with an arch-devil, a demon-prince, or perhaps Charon the Boatman. Defeating such a creature will gain the player many experience points which is the basis for scoring in xrogue. It is very difficult to return from the Dungeons of Doom alive. Very few players have won this game.
