Angband is a dungeon-crawling roguelike video game derived from Umoria. It is based on the writings of J. R. R. Tolkien, in which Angband is the fortress of Morgoth. The current version of Angband is available for all major operating systems, including Unix, Windows, Mac OS X, and Android. It's identified as one of the "major roguelikes" by John Harris. Gameplay The goal of Angband is to survive 100 floor levels of the fortress Angband in order to defeat Morgoth. The game is reputed to be extremely difficult. The player begins in a town where they can buy equipment before beginning the descent. Once in the maze-like fortress, the player encounters traps, monsters, equipment, and hidden doors. With the help of found objects and enchantments, the player's attack and defense power increases, and can even neutralise specific attacks. The player also meets characters and finds artifacts from Tolkien's legendarium. Angband gameplay emphasises combat and careful resource management. The player has a certain amount of health points. Although Angband records the player's progress to a save file, it does not allow one to resume a saved game in which the player character has already been beaten. The levels are procedurally generated, allowing for a unique game in every play. Development The first version of Angband was created by Alex Cutler and Andy Astrand at the University of Warwick in 1990. They wanted to expand the game Umoria by adding items, monsters, and features. After Cutler and Astrand, the source code was maintained at the University of Warwick by Geoff Hill and Sean Marsh. They released "2.4.frog_knows", which was enhanced by others and widely ported to non-Unix platforms. Following their departure, the later principals of Angband have included Charles Swiger, Ben Harrison, and Robert Rühlmann. Harrison was the maintainer responsible for the "Great Code Cleanup", modularizing, extending, and greatly improving the readability of the Angband source code. This in turn led to the large number of variants currently available, as well as the rather large number of ports. Like other maintainers, he eventually moved on to other interests, passing the title to Robert Rühlmann in 2000. Rühlmann's contributions included releasing version 3.0, which included many monster and object changes contributed by Jonathan Ellis. He also introduced Lua, a lightweight scripting language, with the intention of simplifying development of both the main game and its variants. The Angband community, however, did not generally
