It is a good game, one of a kind, but you might only want to play it for multiplayer purposes. After a while you cannot look past the huge amount of mistakes the AI (on your team) make. They can block eachother so they will not shoot at a suspect holding an AK47, thus both being eliminated. Don't let them drop the flashbangs etc. in a room either. Every now and then they will simply stand in the doorway, in line of sight with a terrorist, waiting for the device to detonate, thus being elimated before detonation of the device. At times it's just best to leave your team behind en clear most of the map on your own.
