DOD:S has just been switched to the new steam content delivery system. Among the highlights of this move are faster downloads, faster map loads and the ability to install DOD:S to another drive on your computer.

We also have the first DOD:S beta server up at:
67.212.160.118:27015

To get into the beta follow these instructions:
1.) In the Steam client, right click on “Day of Defeat:Source” in the games list, and select “properties.”
2.) Select the “betas” tab.
3.) Select the “steampipe” beta.
4.) Close the properties dialog.
5.) Click “play” to launch Day of Defeat:Source.
6.) You will be prompted with a dialog prompting you that existing content will be converted to the new format.
7.) The conversion process will take a few minutes.
