... self.. You will need a source port engine to run it. e.g. PrBoom or Doom Legacy, there are several source ports that compile under Linux. It also requires that you have a Doom2 IWAD to play.
I should again mention that a deathmatch wad, in this case a mega wad, has been created to play online or in a LAN scenario, competitively against other players on a network.

At some point I do plan however to create my own Doom source engine.. If there isn't enough already, heh.
