From what I understand day of defeat source is a great game. I play it and you can get a non steam version also of it. As it's made by valve same as css it kinda has that furious liquid motion as css does and I've wondered if warlords has ever considered 1 server for this game. It's a fantastic game to play as was as popular as css and tf2 once but dont hear much about it these days although it lives on. massive guns from the wwii era too.
