Doomsday

The Doomsday Engine is a source port with support for Doom, Heretic, and Hexen. It was originally based on the Hexen source code, but most of it were later rewritten completely. Doomsday is only an engine; you will need a Game Plugin if you want to play anything. Three offical Plugins are being developed alongside the engine: jDoom, jHeretic and jHexen, with two unoffical plugins WolfTC and Doom64TC. The latest stable version of Doomsday is. The current development version is 1.9.0 beta4.

The Doomsday Engine, jDoom, jHeretic and jHexen are developed by Jaakko Keränen (skyJake), with the help of various others including DaniJ and Yagisan.

Support and development is often carried out in #doomsday on irc.freenode.net, with long term planning done at dengDevs.
