Day of Defeat (commonly abbreviated as DoD) is a team-based multiplayer World War II first-person shooter video game set in the European Theatre of World War II. Originally a modification of the 1998 game Half-Life, the rights of the modification were purchased by Valve Corporation and released as a full retail title in 2003. The game was generally well-received, with an aggregate score of 79/100 on Metacritic.
Set in the midst of World War II, Day of Defeat includes no single-player campaign, with focus left only on the game's multiplayer aspects. The title lends favor towards teamwork and features objective-based gameplay in combination with its system of classes. Maps are primarily made up of narrow paths, all of which typically lead to a few key locations.
Titled Day of Defeat: Source, an official remake of the game was released by Valve in 2005. Utilizing the then-new Source engine, the remake featured various improvements over its predecessor, including updates to gameplay, graphics, and audio functionality.
