Counter-Terrorist Force is a pure “player vs. player” (1 on 1) game where the main focus is on tactics and realistic combat. The game is played from both sides of the conflict. One person plays the terrorists and the other takes the role of counter-terrorist. Not only do you execute missions, you also run your own counter terrorist corporation and try to work your way up from scratch. You will also fight occasionally as a terrorist so that your friends can play as counter terrorist troopers too. Game play can either be single missions to improve your corporation, or otherwise in campaign mode where two campaigns are interwoven – you and your opponent take turns as terrorists - and you both have your own counter-terrorist unit to run every second game in your individual campaign.
