Day of Defeat: Source

Day of Defeat: Source features multiplayer, team-based gameplay set in the WWII European theatre of operations. Players choose a role and tackle goal-oriented missions based on historical operations. Day of Defeat: Source takes the classic gameplay of the original Day of Defeat and improves the experience with Source, the advanced engine technology Valve created for "Half-Life 2." With this technology, DoD: Source offers state of the art graphics (including support for HDR lighting) in optimized versions of popular maps, plus redesigned sound and all new player, weapon, and world models. New features include: Completely updated maps to take full advantage of the Source engine replaces, integrated physics simulation for ragdolls and physically simulated objects, higher resolution textures throughout, bump mapping, specular lighting, and other graphic effects, all powered by advanced Source engine technology, completely redesigned user interface, all new voice, weapon, and ambient sounds.
