Acquire this game, put it on the highest difficulty, and play the first level. It's that good. Despite the dubious idea of a police FPS, this game portrays the far more paranoid and anxious side of CQC than any other shooter released. Not to demean other shooters as being juvenile or unrealistic, as SWAT is far from a realistic game itself, but what it is, and what makes it unique, is that it's a focus on the psychological aspects of a first-person shooter without overt narratization or storytelling. Put less pretentiously, it's like watching incredibly loud and extremely tense SWAT arrest videos on youtube over and over again, but (ostensibly) divorced from America's gross socio-political context and the dubious idea of a "non-violent" police force. It's exhilarating.
