Linley's Dungeon Crawl (or just Dungeon Crawl or Crawl) was a roguelike computer game originally programmed by Linley Henzell in 1995, and first released to the general public on October 2, 1997.[14] The game had a quirky license based on Bison's license and the NetHack License;[15] Stone Soup has contacted every past contributor and relicensed to GPLv2+.

Crawl starts with the player's choice of one of over twenty races: several different types of elves, dwarves, humans, ogres, tengu, centaurs, merfolk, and other fantasy beings. Racial selection sets base attributes, future skill advancement, and physical characteristics such as movement, resistances, and special abilities.

Subject to racial exclusions, the player next chooses a character class from among over twenty selections. Classes include the traditional roles of fighter, wizard, and thief as well as specialty roles, among them monks, berserkers, assassins, crusaders, and elemental spellcasters. Wanderers represent an atypical option and receive a random skill set. Together, class and race determine base equipment and skill training, though characters may later attempt to acquire any in-game skill.[16]

The Crawl skill system covers many abilities, including the ability to move freely in armor or silently, mount effective attacks with different categories of weapons (polearms, long or short blades, maces, axes, and staves), master spells from different magical colleges (the elements, necromancy, conjuration, enchantments, summoning, etc.), utilize magical artifacts, and pray to divinities. Training occurs through repetition of skill-related actions (e.g., hitting a monster with a longsword trains long blades and fighting skills), using experience from a pool refilled as the player defeats monsters.

John Harris, in his "@Play"[16] column states that the experience pool system "deftly avoids the many problems of a skill-based development system", mainly praising the need to move on through the course of the game to further improve a PC's skills. In the same article, John Harris states that this experience system "is probably the best skill system yet seen in any roguelike; it could make a claim at being one of the best in any CRPG."

Religion within Crawl is a central game mechanic. Its diverse pantheon of gods reward character conformance to particular codes of conduct. Trog, the berserker god, expects abstinence from casting spells and offers aid in battle, whereas Sif Muna expects frequent spellcraft in exchange for magical assistance and gifts of spellbooks. Some deities campaign against evil, matched by a god of death who revels in indiscriminate killing, while others prove unpredictable objects of worship. Xom, an example of the latter, toys with followers, meting out punishments and showering gifts on inscrutable whims.[17]

The goal of Crawl is to recover the "Orb of Zot" hidden deep within a dungeon complex. To achieve this objective, characters must visit various dungeon branches, such as the Orcish Mines or The Lair of Beasts, which often branch further in to additional areas, like the Elven Halls or The Swamp, and obtain at least three "Runes of Zot" with which to gain access to the Orb. Fifteen different runes can be obtained in any particular game, and obtaining all of them is generally considered an extra feat. While all the possible 654 race/class combinations have been won on the online servers, only 186 of them were ever played online as an all-rune win (as of 2010-08-24). Dungeon maps in Crawl persist, as in NetHack.

The last official versions of Linley's Dungeon Crawl were 4.0.0 beta 26, from March 24, 2003, and a later alpha release, version 4.1.0, dating from July 2005.[18]

Version 400b26e070t, a popular last community release, includes the 2003-2004 Patches (Darshan Shaligram) and updates the game to the standard tile version (M. Itakura, Denzi, Alex Korol, Nullpodoh).

The game has been ported to the Nintendo DS as DSCrawl.

Dungeon Crawl Stone Soup was begun in 2006 by Darshan "greensnark" Shaligram and Erik Piper as an attempt to restart Crawl development, which had progressed slowly in the years since Linley Henzell, creator of the original Linley's Dungeon Crawl, had retired from developing the game. Several interesting patches had been made to the game in recent years, particularly one by Shaligram known as the 'Travel patch', which borrowed the implementation of Dijkstra's algorithm from NetHack to provide an auto-exploration ability in game. These patches were compiled into the Stone Soup project, which was eventually released publicly on Sourceforge.[19]

Stone Soup has since then developed an unprecedented variety of extensions which fit into this general vein of "play aid", such as allowing searching through every item ever discovered by regular expression.[20] Additionally, Stone Soup has made a number of user interface improvements, such as mouse interaction and an (optional) graphical user interface.[19]

In order to avoid featuritis, Stone Soup has also pruned gameplay elements which they considered superfluous, including several races and a magical school.[21] The development team has also expressed a desire to maintain the current total length of the game, and so as new areas are added to the dungeon, old ones have been shortened or even removed to compensate.[22]
