Adonthell is an open-source role-playing game engine project that has been in development since 1999. Designed for creating graphical, single-player 2D games, it draws inspiration from Western RPGs such as Ultima VII and Planescape: Torment, while aiming for the visual style of console classics like Chrono Trigger and Secret of Mana. The project’s work is showcased through Waste’s Edge, a small but complete demo game available for GNU/Linux, Mac OS X, and Windows.

Adonthell also provides a project wiki with documentation and resources for aspiring developers, offering information that can be maintained and updated by the community. Visitors can explore galleries featuring artwork and scenery, learn about the project, and find guidance or ways to contribute. As an open-source development initiative, Adonthell brings together game technology, creative content, and supporting documentation to help realize a distinctive 2D RPG experience.

The project is maintained by the Adonthell Team, with the site crediting contributors for its design and content
