"Day of Defeat has quietly been one of the most played online action games for the past three years," said Gabe Newell, president and founder of Valve. "Day of Defeat: Source represents a major leap forward in both graphics and gameplay, and pushes the Source engine harder than any other Source project. "

Available via Steam for just $19.95 and in the Counter-Strike: Source retail package, DoD: Source is a rebuild from the ground up of Day of Defeat on the Source engine. DoD: Source is now available, those who purchased the Half-Life 2 Silver or Gold Steam offers will receive access to play the moment the game is made available.
