Day of Defeat: Source is a World War II multiplayer first-person shooter developed and published by Valve for the PC (with both a retail release and a digital Steam release) on September 26, 2005. It was later updated for Mac support on July 12, 2010 and Linux support on March 14, 2013.
The game is a remake of the original Day of Defeat using Valve's Source engine (in similar vein to Counter-Strike: Source) to update its visual and sound design while tweaking the gameplay mechanics.
Like its predecessor, players are split into two forces in the European Theatre of World War II: the "Allies" (U.S. Army) and the "Axis" (German Wehrmacht). In pure infantry-based combat, these forces must fight over strategic points located throughout the battlefield (some points requiring multiple players to capture). While this remake only had this game mode at release, a separate "Detonation" mode was added later (in which players must destroy key enemy equipment using their timed explosives while defusing enemy explosives).
Like most of Valve's Source engine offerings, the game is often used as a test bed for both Steam and engine updates. It is the first Source game to incorporate High Dynamic Range lighting (predating the standalone Lost Coast tech demo level for Half-Life 2). Along with a variety of updates throughout the years (including new maps, the Detonation game mode, gameplay tweaks, and Steam Trading Card support), the game's engine received a major update on July 3, 2008 (upgrading it to the version used in The Orange Box, allowing for new visual effects, stat-tracking, user avatar support, and achievements).
Unlike the game's predecessor, Day of Defeat: Source does not include faction-specific classes (such as the Sergeant) or British Army classes for the Allies. Both forces carry the same type of classes with near-equal capabilities.
All classes, other than the Assault Infantry, carry either a Trench Knife (Allies) or Entrenchment Spade (Axis) as their melee weapon.
Built for long-ranged combat, the Rifleman carries a powerful battle rifle, which can be used (in the right hands) to take out enemies in long ranges. Although these rifles are not as efficient as sniper rifles (and M1 Garands cannot reload until their current clip is empty), they have the additional ability to fire specially-mounted grenades at long ranges.
Pressing Secondary Fire while wielding either battle rifle allows the player to zoom in through its iron sights.
- Allies: M1 Garand with eleven 8-round clips and 2 Rifle Grenades
- Axis: Karabiner 98k with thirteen 5-round clips and 2 Rifle Grenades
Built for short-ranged combat, the Assault Infantry carries a fast-firing sub-machine gun, a backup handgun, and two types of grenades (including a smoke grenade to limit visibility of Snipers and Machine Gunners).
While the Assault Infantry cannot equip a melee weapon, pressing Secondary Fire while wielding either sub-machine gun allows the player to throw a quick punch (allowing greater versatility in close-ranged combat).
Built for medium-ranged combat, the Support Infantry carries an assault rifle with selective firing modes (allowing semi-automatic fire for accuracy and control in longer ranges). In addition, they carry two explosive grenades (making them very useful against tight groups of enemies and entrenched Snipers and Machine Gunners).
Pressing Secondary Fire while wielding either assault rifle changes its firing type (from semi-automatic to fully automatic).
A special version of the Rifleman, the Sniper carries a powerful scoped sniper rifle which, in the right hands, can help control a huge portion of the battlefield. They also carry backup handguns for close-quarters combat.
Pressing Secondary Fire while wielding either sniper rifle allows the player to zoom in through its scope.
- Allies: Springfield M1903 with thirteen 5-round clips, Colt M1911
- Axis: Karabiner 98k (scoped) with thirteen 5-round clips, Walther P38
The strongest suppression and defense class in the game, the Machine Gunner carries a powerful and fast-firing machine gun (alongside a backup handgun for close-quarters combat). Due to the weapon's capabilities, most servers restrict the amount of active Machine Gunners to a very low amount.
Both machine guns have notorious kickback when firing from the hip (preventing players from acting like Rambo). Pressing Secondary Fire while wielding either machine gun and either prone or in front of a ledge/window deploys the bi-pod to keep the weapon completely stable (at the cost of mobility, leaving them open to sniper fire). Pressing it again retracts the bi-pod.
- Allies: M1919 with three 150-round belts, Colt M1911
- Axis: MG42 with two 250-round belts, Walther P38
Despite the lack of vehicles in the game, the Rocket Infantry can be a wildcard class due to its rocket launcher (which is useful against entrenched Snipers and Machine Gunners) and unique fast-firing secondary weapon.
Rocket launchers cannot be fired from the hip and must be shouldered by pressing Secondary Fire while wielding either of them. Movement is slow while shouldering them.
All maps, with the exception of Argentan, Palermo, and Colmar, are based on their original Day of Defeat maps.
