Swat 4 is the best tactical shooteri have ever played, there is so much realism, the mechanics are great, and the gameplay is very good to. If you follow the story, and listen to the briefing that they give you and listen to the 911 calls, you see just how dark it can get. Especially with the 2nd mission. I don't want to spoil it for people that haven't played it, but it's a must play.
