Free Half-Life addon module that allows you to play online as either a terrorist or a counter-terrorist. The counter-terrorists must rescue the hostages from the terrorists or stop the terrorists from bombing targets. The weapons in the game are totally realistic, and the gameplay is as realistic as possible. One shot can kill, and once you're dead, you're dead until the next game. None of this silly "respawn and blast the badguys again" stuff. Luckily, games usually last only about 5 minutes. Visit for more info.
