Doomsday

The Doomsday Engine is a source port with support for Doom, Heretic, and Hexen. It runs on Linux, Mac OS X, and Windows, and is presently developed by Jaakko Keränen (skyjake) and Daniel "Danij" Swanson. Former developers include Jamie "Yagisan" Jones.

Doomsday itself is a multi-game supporting engine and developed along with it are numerous plugins; e.g. game plugins which are necessary to actually play a game using it. Four official plugins are being developed by the core deng team alongside the engine: jDoom, jHeretic, jHexen and recently, jDoom64. In Addition to the official game plugins, there exists so-called third-party plugins such as WolfTC. The current stable version of Doomsday is. The current development version is 1.9.0 beta 5.1.

Since mid 2005, the deng team has been at work on the next major iteration of Doomsday; version 1.9.0 and this newest branch of Doomsday remains in beta.

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

History
The project started out as a dedicated source port with support for Hexen. Later, versions of the project were created for Doom and Heretic. Soon after which, common functionality among the projects was collected together and split into a common core component; the Doomsday engine was born.

Although originally based upon the Hexen source code the engine has since been rewritten completely.
