Langband is a roguelike written in Common Lisp. It is distributed under a GNU General Public License (GPL). Langband has been designed to be a roguelike engine where you can write and/or customise your own variant/plugin which will not interfere or ruin other code. To do this it uses the powerful object-oriented features of Common Lisp (e.g multi-methods and generic functions) as well as the functional features which allows the engine to treat user-code (classes, functions, ...) as first-class objects and not just ad-hoc add-ons.

Langband has been influenced by and has been inspired by regular (or vanilla) Angband, and due to the design of Langband can (more or less) run regular Angband as a plugin to the Langband-engine. Langband is not limited to this and will be extended with other variants.

Currently Langband is in development, and the current version is v0.1.6. The project is in active development, but needs assistance. Graphics, ideas, code and testing are all welcome. Please send me a mail and I'll get back to you ASAP.
