What is Counter: Definition and 223 Discussions

Counter-Strike (CS) is a series of multiplayer first-person shooter video games in which teams of terrorists battle to perpetrate an act of terror (bombing, hostage-taking, assassination) while counter-terrorists try to prevent it (bomb defusal, hostage rescue). The series began on Windows in 1999 with the release of the first game, Counter-Strike. It was initially released as a modification ("mod") for Half-Life that was designed by Minh "Gooseman" Le and Jess "Cliffe" Cliffe before the rights to the mod's intellectual property were acquired by Valve, the developers of Half-Life, who then turned Counter-Strike into a retail product.
The original Counter-Strike was followed by Counter-Strike: Condition Zero, developed by Turtle Rock Studios and released in March 2004. A previous version of Condition Zero that was developed by Ritual Entertainment was released alongside it as Condition Zero: Deleted Scenes. Eight months later, Valve released Counter-Strike: Source, a remake of the original Counter-Strike and the first in the series to run on Valve's newly created Source engine. The fourth game in the main series, Counter-Strike: Global Offensive, was released by Valve in 2012 for Windows, OS X, Xbox 360, and PlayStation 3. Hidden Path Entertainment, who worked on Counter-Strike: Source post-release, helped to develop the game alongside Valve.There have been several third-party spin-off titles created for Asian markets over the years. These include the Counter-Strike Online series, Counter-Strike Neo, and Counter-Strike Nexon: Studio.

    Why is my plasma globe causing a geiger counter to go crazy?

    The reason I did not place this in the nuclear engineering forum is because I feel that it is closer to an electrical engineering problem than a nuclear engineering problem.Now to the question. I recently got another geiger counter and a plasma globe for my birthday. Being the person I am I...

    How to counter "everything is a construct" worldview?

    Many of the people in humanities I encounter seem very wedded to mindset I refer to as "construct = everything". For example, they say bazar things such as gender is 100% a construct. They say this as if sexual selection doesn't exist (to be fair, they honestly don't seem to know it exists)...
