A first person shooter originally made by a man called Gooseman in 1999 as a modification to the game Half-Life. The game consists of two teams, the Counter-Terrorists and Terrorits. Each team purchases weapons at the start of a round and tries to either kill every member of the opposite team or complete an objective.
The game has become an extremely popular FPS over the years, and despite running on a 7 year old game, is still played by many people.

However, many people have hatreds toward the game because of it's popularity and will insult it given a moments notice. Even people who have not played the game or only played for a short amount of time have very biased opinions towards the game.
Despite what many people say, the game is very fun with a good community. There is a reason why it is so popular after all.

Counter-strike (CS). An insanely popular modification for the Half-Life engine imfamous for its generally less-than-friendly community, strange non-realism, abusive server administrators, and high concentration of hackers. The modification was orinally headed by "gooseman", and was adopted by Valve Software as a commercial product. Its only continuation to date, Counter-Strike: Source, was developed by Valve as a graphically enhanced version of the game.

Loved by millions, hated by more or less the same, counter-strike has been the debate topic of many for a long time.

Counter-Strike remains, to this date, the most played online game ever created.
We're going to go scrimming on CS, want to come?
Nah, I'm updating Counter-Strike: Source

A once respected Half-Life modification. Nowdays, it's just another online-chat, where 13-year olds can release their teenage angst on others, by calling them "fags", "cheaters" or basically anything else that they can possibly come up with. And of course, like all popular online-games, it's full of cheaters (real cheaters), retards, admins who have no sense of justice and people who abuse every single bug they can find for their own good.

It has it's good points though: First of all, called clan matches (with the right group). I'm pretty sure that no other game has been able to create that kind of exitement, and propably will never be. Second of all, it actually needs skill. You're welcome to try your luck on some avarage cs public server, if you think its all "Run around and shoot people".

The things that took away this game's glory are Valve, cheaters & 10-15 -year old kids. Without those 3 things, this game would propably still be the most respected game there is.
Skill, reflexes & strategy are the three most essential things if you want to be a good counter-strike player, or at least that's what they were, if you go back in time about 3 years
