The official site for Day of Defeat today announced the linux build release at 11am PST(2pm EST) followed by the Windows client at 3pm PST. Day of Defeat is a World War II multiplayer total conversion of "Half-life." DoD attempts to recreate WWII battles in both fictional and non-fictional environments. DoD puts you in the shoes (rather, combat boots!) of either an Allied or Axis soldier circa 1944, Western Europe.
