update that includes new features and functionality developed in collaboration with Hidden Path Entertainment. These include 144 (now 146) new achievements, a new domination and revenge system, similar to that of Team Fortress 2, player stats, an upgrade to the Source engine and more. On June 23, 2010, Valve released the beta to the public alongside the promised OS X version. On February 5, 2013, Valve released a port of Counter-Strike: Source for Linux. Modifications Counter-Strike: Malvinas Counter-Strike: Malvinas is a multiplayer first-person shooter modification of Counter-Strike: Source, developed and distributed by Argentine web hosting company Dattatec. The mod was released worldwide on 4 March 2013 and utilizes the Source game engine. The game is set in Stanley, the capital of the Falkland Islands, and revolves around a group of Argentine special forces capturing the archipelago from British "terrorists". The objective of the game is similar to that of the Counter-Strike series; each round is won by either detonating a bomb or by eliminating all members of the enemy team. Counter-Strike: Malvinas pays homage to the 1982 Falklands War, in which an estimated 650 Argentine and 255 British servicemen died. The mod prompted strong controversy in the United Kingdom; Dattatec's website was targeted by British hackers on 27 March 2013. Reception Counter-Strike: Source was met with positive reviews from professional critics. Metacritic, a review aggregator website, awarded Source a rating of 88 out of a possible 100 based on 9 critic's reviews. Jeff Haynes of IGN said the game was "much more detailed, featuring many more polygons per model, bump mapping and other graphical enhancements" compared to the original. Sequel On August 12, 2011, Valve announced the production of a successor to Counter-Strike: Source, entitled Counter-Strike: Global Offensive. Global Offensives development began in March 2010 when Hidden Path Entertainment attempted to port Counter-Strike: Source onto video game consoles prior to the end of its lifespan. During its development, Valve saw the opportunity to turn the port into a full game and expand on the predecessor's gameplay. Competitive play 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. References 2004 video games Asymmetrical multiplayer video games Counter-Strike Tactical shooter video
