Odamex is a free, cross-platform (Mac, Windows, Linux) modification of the Doom engine that allows players to easily join servers dedicated to playing Doom online.

A copy of Doom, Doom II, Freedoom or Chex Quest is recommended to play it. If you do not own Doom, it can be purchased on GOG or Steam.
