'''''Counter-Strike: Source''''' is a tactical first-person shooter video game developed by Valve and Turtle Rock Studios. Released in October 2004 for Windows,<ref name="Steam News 327" /> it is a remake of ''Counter-Strike'' (2000) using the Source game engine. As in the original, ''Counter-Strike: Source'' pits a team of counter-terrorists against a team of terrorists in a series of rounds. Each round is won either by completing an objective (such as detonating a bomb or rescuing hostages) or by eliminating all members of the enemy team. The game was initially bundled with all retail and digital copies of ''Half-Life 2'',<ref>Thorsen, Tor.

==Gameplay== [[File:Counter-Strike Source screenshot.png|thumb|left|A screenshot from the map "cs_italy". The player is holding a Maverick M4A1 Carbine.]] ''Counter-Strike: Source'' retains its team-based objective-oriented first-person shooter style gameplay. The aim of playing a map is to accomplish a map's objective: defusing the bomb, rescuing all hostages, or killing the entire opposing team. The ultimate goal of the game is to win more rounds than the opposing team. Once players are killed, they do not respawn until the next round, though this depends on which server people play on. This gameplay feature distinguishes Counter-Strike from other first-person shooter games, where players respawn instantly or after a short delay.

Shooting while moving dramatically decreases accuracy, and holding the trigger down to continuously shoot produces severe recoil. The severity of damage induced by weaponry is dependent upon the specific locations of hits, with hits to the head being most lethal and shots which make contact elsewhere causing lesser loss of health. Damage is also affected by the distance, and if the target wears protection.{{Citation needed|date=December 2025}}

==Development== ===Initial release=== ''Counter-Strike: Source'' is a remake of the original ''Counter-Strike'' built on Valve’s Source engine and the third major entry in the ''Counter-Strike'' series. Announced on May 12, 2004 during E3 presentation as the multiplayer counterpart to ''Half-Life 2'', it became the first Source engine game released by Valve Software, arriving on Steam for Windows on October 7, 2004, a month before ''Half-Life 2'' itself.<ref name="Steam News 327" /><ref name="raisebar">{{Cite book |last=Hodgson |first=David |title=Half-Life 2: Raising the Bar |publisher=Prima Games |year=2004 |isbn=978-0-7615-4364-0 |page=57}}</ref><ref>{{cite news |title=Half-Life 2 & Counter-Strike Source News |url=http://www.shacknews.com/ja.zz?comments=31857 |work=Shacknews |date=May 12, 2004 |access-date=May 2, 2026|archive-url = https://web.archive.org/web/20040605072801/http://www.shacknews.com/ja.zz?comments=31857|archive-date = June 5, 2004|url-status = dead}}</ref><ref name="updatehistory" /> The first public beta became available on August 11, 2004 through the Valve Cyber Café Program, followed by a wider beta release on August 18 for owners of ''Counter-Strike: Condition Zero'' and users who received ''Half-Life 2'' vouchers bundled with select ATI Radeon video cards.<ref name="updatehistory">{{cite web |title=Counter-Strike: Source update history |url=http://www.steampowered.com/platform/update_history/index.php?id=240 |publisher=Valve |access-date=July 1, 2008|archive-url = https://web.archive.org/web/20071121194417/http://www.steampowered.com/platform/update_history/index.php?id=240&skin=0|archive-date = November 21, 2007|url-status = dead}}</ref><ref>{{cite news |title=Counter-Strike: Source beta begins |url=http://www.gamespot.com/pc/action/counterstrikesource/news.html?sid=6104577 |work=GameSpot |publisher=CNET Networks |date=August 11, 2004 |access-date=July 1, 2008|archive-url = https://web.archive.org/web/20140314043506/http://www.gamespot.com/articles/counter-strike-source-beta-begins/1100-6104577/|archive-date = March 14, 2014|url-status = dead}}</ref><ref>{{cite web |title=Counter-Strike: Source Strike ATI Customer |url=http://ati.amd.com/buy/promotions/cssource/index.html |publisher=Advanced Micro Devices |access-date=July 1, 2008|archive-url = https://web.archive.org/web/20100409071711/http://ati.amd.com/buy/promotions/cssource/index.html|archive-date = April 9, 2010|url-status = dead}}</ref> The game was later included in ''Half-Life 2'' retail bundles released on November 16, 2004.<ref>{{cite web|access-date=October 3, 2008|url=http://pc.gamespy.com/pc/half-life-2/554654p1.html|title=Blow Off Some Steam and Pre-Order Half-Life 2 (PC)|publisher=GameSpy|date=October 6, 2004|author=Autrijve, Rainier Van|archive-date=October 6, 2008|archive-url=https://web.archive.org/web/20081006131105/http://pc.gamespy.com/pc/half-life-2/554654p1.html|url-status=live}}</ref>

''Counter-Strike: Source'' was developed primarily in-house at Valve, with contributions from the original ''Counter-Strike'' creators Minh Le and Jess Cliffe, as well as members of the ''Day of Defeat'' team.<ref name="raisebar" /> Following the game’s release, Turtle Rock Studios also became actively involved in supporting the game through post-release updates, having previously collaborated with Valve on ''Counter-Strike: Condition Zero'' and the Xbox port of the original ''Counter-Strike''.<ref name="GIHistory">{{cite magazine|url=https://www.gameinformer.com/b/features/archive/2014/01/31/life-after-death-the-story-of-turtle-rock-studios.aspx|title=Life After Death: The Story Of Turtle Rock Studios|first=Ben|last=Hanson|magazine=Game Informer|date=January 31, 2015|access-date=August 18, 2015|archive-url=https://web.archive.org/web/20150924052138/http://www.gameinformer.com/b/features/archive/2014/01/31/life-after-death-the-story-of-turtle-rock-studios.aspx|archive-date=September 24, 2015|url-status=dead}}</ref>

The main goal of the developers was to transfer ''Counter-Strike'' to the Source engine without altering the core gameplay mechanics.<ref name=CaVG2004 /> The engine’s new features allowed maps to become significantly more detailed, introducing physical objects such as barrels, bottles, and tires scattered across environments, all affected by the game’s physics system.<ref name=CaVG2004>{{cite news |title=COUNTER-STRIKE SOURCE: VALVE SQUEEZED FOR INFO |url=http://www.computerandvideogames.com/front_index.php |work=Computer and Video Games |date=August 13, 2004 |access-date=May 23, 2026|archive-url = https://web.archive.org/web/20040814011956/http://www.computerandvideogames.com:80/front_index.php|archive-date = August 14, 2004|url-status = dead}}</ref><ref name=CSN2004>{{cite news |title=cs: source impressions |url=http://www.csnation.net/articles.php/article_192/3/ |work=CS-Nation |date=July 16, 2004 |access-date=May 22, 2026|archive-url = https://web.archive.org/web/20040820015021/http://www.csnation.net/articles.php/article_192/3/|archive-date = August 20, 2004|url-status = dead}}</ref> Grenade trajectories, explosions, and their impact effects were also made more realistic.<ref name=CaVG2004 /><ref name=CSN2004 /> Player bodies after death were likewise redesigned — instead of using predefined death animations, the game introduced ragdoll physics.<ref name="raisebar" /> Sound effects were also reworked to better match environmental acoustics, while support for 5.1 and 7.1 surround sound systems was added.<ref name="raisebar" /> In addition, the maximum number of players supported on a server was doubled to 64.<ref name="raisebar" />

The texture detail on the maps was significantly increased, with the resolution of many textures increasing fourfold compared to the original game, alongside improved 3D models.<ref name=CaVG2004 /><ref name=CSN2004 /> Source also made extensive use of advanced DirectX 9 rendering features such as bump mapping, normal mapping, and specularity, giving surfaces greater depth, lighting detail, and reflectivity.<ref name="raisebar" /><ref name=CaVG2004 /> The engine’s reflective surface technology was used extensively through cube mapping — for example, weapons equipped with optical scopes could display reflections of the surrounding environment on the lens when not zoomed in, although other player models were not rendered in those reflections. Source also introduced support for 3D skyboxes, allowing environments to appear as though they stretched for miles beyond the playable area, making maps feel less like enclosed arenas and more like believable real-world locations.<ref name=CaVG2004 /><ref name=CSN2004 />

Unlike previous ''Counter-Strike'' titles, ''Counter-Strike: Source'' launched without the riot shield and without the Assassination game mode, featuring only Hostage Rescue and Bomb Defusal scenarios.<ref name=CSN2004 /> At release, the game also contained only one character model per team — Phoenix Connexion for the Terrorists and SEAL Team 6 for the Counter-Terrorists — while the selection of maps was relatively small, with nine included in total.<ref name=CaVG2004 /><ref name=CSN2004 /> Many of the launch maps resemble direct ports of classic ''Counter-Strike'' maps with redesigned textures and relatively limited environmental detail. However, with the addition of new maps over the following months, the visual quality and level of detail improved significantly, eventually reaching a standard comparable to ''Half-Life 2''.

===Post-release===

From December 2004 to January 2006, through subsequent updates, Turtle Rock Studios remade six classic maps from previous ''Counter-Strike'' titles that were missing at launch, and introduced bot support, which later served as a precursor to the AI systems used in ''Left 4 Dead''.<ref name="updatehistory" /><ref name="GIHistory" /><ref>[https://web.archive.org/web/20060205164119/http://www.turtlerockstudios.com/ Turtle Rock Studios homepage].

One of the most controversial updates in the game’s history arrived on November 1, 2006 with the Dynamic Weapons Pricing system, which altered weapon prices weekly based on player demand statistics from the previous week.<ref>{{cite web |url=https://store.steampowered.com/oldnews/814 |title=Counter-Strike: Source Update Released |access-date=July 1, 2008 |publisher=Valve |date=November 1, 2006|archive-url = https://web.archive.org/web/20080926011350/http://store.steampowered.com/news/814/ |archive-date = September 26, 2008 |url-status = live}}</ref><ref>{{cite news |last=Goldstein |first=Maarten |title=Counter-Strike: Source Switching To Dynamic Weapon Pricing |url=http://www.shacknews.com/article/43978/counter-strike-source-switching-to |work=Shacknews |date=September 22, 2006 |access-date=March 14, 2014|archive-url = https://web.archive.org/web/20140314044454/http://www.shacknews.com/article/43978/counter-strike-source-switching-to|archive-date = March 14, 2014|url-status = live}}</ref><ref>{{cite web |url=http://steampowered.com/stats/csmarket/algorithm.html |title=Pricing Algorithm |access-date=July 1, 2008 |publisher=Valve|archive-url = https://web.archive.org/web/20121125075639/http://www.steampowered.com/stats/csmarket/algorithm.html|archive-date = November 25, 2012|url-status = dead}}</ref> The update also removed the ability to purchase ammunition separately, automatically providing ammo whenever a weapon was bought. Although the system was intended to diversify gameplay and weapon usage, it faced immediate criticism from the community and was eventually removed.

On June 23, 2010, Valve, in collaboration with Hidden Path Entertainment, released a major update that ported the game to The Orange Box engine, replacing the older Source 2006 version, commonly known as v34.<ref name="Steam News 3976">{{cite web | url = http://store.steampowered.com/news/3976/| title = Counter-Strike: Source Update Released | access-date = June 23, 2010 | work = Steam | publisher = Valve|archive-url = https://web.archive.org/web/20140222135654/http://store.steampowered.com/news/3976/|archive-date = February 22, 2014|url-status = live|date = June 23, 2010}}</ref><ref name="Steam News 3805">{{cite web | url = http://store.steampowered.com/news/3805/| title = Counter-Strike: Source Update Now in Beta | access-date = June 23, 2010 | work = Steam | publisher = Valve|archive-url = https://web.archive.org/web/20100514153955/http://store.steampowered.com/news/3805|archive-date = May 14, 2010|url-status = live|date = May 11, 2010}}</ref> This update introduced numerous gameplay and technical improvements, including 144 new achievements, MVP Awards, a domination and revenge system inspired by ''Team Fortress 2'', player statistics, a redesigned scoreboard, and the Mac OS X version.<ref name="Steam News 3976" /><ref name="steam css">{{cite web | url = https://store.steampowered.com/css| title = Counter-Strike: Source on Steam | access-date = June 23, 2010 | work = Steam | publisher = Valve|archive-url =https://web.archive.org/web/20100626103855/https://store.steampowered.com/css|archive-date = June 26, 2010|url-status = live}}</ref> However, the update was also criticized for several drawbacks, including a noticeable decrease in average frame rates, the restriction of custom server tick rates by enforcing a default value of 66, and incorrect player interactions with physics objects.

On September 15, 2011, Valve released another significant gameplay update focused on weapon accuracy, spread patterns, and balancing changes.<ref name="Steam News 6279">{{cite web |title=Counter-Strike: Source Update Released |url=https://store.steampowered.com/oldnews/6279 |website=Steam |publisher=Valve |access-date=May 22, 2026 |archive-url=https://web.archive.org/web/20110923163448/https://store.steampowered.com/news/6279 |archive-date=September 23, 2011 |url-status=live|date = September 15, 2011}}</ref> Combined with the earlier Orange Box transition, these changes divided the ''Counter-Strike: Source'' community, leading many players and servers to remain on older versions such as v34/Source 2006, while others adopted the newer Orange Box and later Source Multiplayer branches.<ref name="css versions">{{cite web |title=CS:Source Is Bizarrely Divided | website=YouTube |url=https://www.youtube.com/watch?v=asJ6Qel0SCc |access-date=22 May 2026 |date=14 April 2025}}</ref> This divide also contributed to the popularity of modified legacy clients such as ClientMod, which emulated older builds of the game.

==Competitive play== {{main|Counter-Strike in esports}}

''Counter-Strike: Source'' has been played in tournaments since shortly after its release. The game received some criticism by the competitive community, who believed the game's skill ceiling was significantly lower than that of CS 1.6. This caused a divide in the competitive community as to which game to play competitively.<ref name="Kane2008">{{cite book|author=Michael Kane|title=Game Boys: Triumph, Heartbreak, and the Quest for Cash in the Battleground of Competitive Videogaming|url=https://books.google.com/books?id=9bulcI9PHJsC|date=19 June 2008|publisher=Penguin Publishing Group|isbn=978-1-4406-3188-7}}</ref>
