One of my favourite tactical shooters I've played. Crushingly difficult at times, and almost unfair, but with a solid set of rules and pretty decent controls for a game of its age and detail. The central theme is simple: a first-person-shooter where shooting your enemies is a last resort. The variety of weapons and gadgets gives you a choice of playstyles, from a frontal assault to a meticulously planned breach. The game is a tad slow, and definitely unforgiving. It's also got co-op multiplayer!
