CounterStrike

The most popular online first person shooter ever, it's a mod based on the engine of half life, and has been around quite some time now, about 6 years, the gameplay is simple in plain view, there are 2 teams that have to kill each other or complete the objectives of a map to win the round. Unlike other fps like popular fps like quake or unreal tournament, the players doesn't get respwaned after he dies, but he waits for the round to finish, and then gets respawned in the buy zone of each map. the first 30 sec are crucial, when each team tryies to get the best position on the map, tactics beeing a very important part of the game. Nowadays, people neglect counterstrike due to it's out of date graphics engine. Since source came out it made some sturr, but not as big as when it first hit the online gaming community. it's a very dificult game to master, takes years to do that. to newbies it's just boring :)
