The game is sold as being compatible with Mac and Linux. But, in actuality, the Mac and Linux versions are unsupported, according to the developers own website. Needless to say, the Linux version doesn't even start.
Whew boy, I've been waiting for this game to come to GOG for years now. For those not in the know, this game fell into copyright hell after its production was discontinued. With only a digital download available for a brief amount of time, people wanting to try this game were either forced to pay steep prices for the increasingly rare physical copies or use less-than-legit means (ironically) of obtaining the game. The fact that this game finally came to GOG feels almost like a holiday for me: the game is finally accessible. As you can probably tell from the title, I love this game and I frequently compare other tactical shooters to it as a benchmark. That's not to say the game is perfect. It definitely shows it's age with the lack of iron-sight aiming, dull textures, and clumsy physics. The AI is also notorious for being infuriatingly stupid at times (for extra fun, take a shot every time you hear “you're standing in my spot sir” or when you're flashbanged by your own teammate). But, this game gets so many things right that you just don't see in modern titles anymore. This game expects you to, for the most part, play the role of a police officer. Unlike Insurgency or ARMA (or even Door Kickers), you're expected to try and save lives rather than eliminate everything in your path. That adds an entire extra layer of complexity on top of the standard tactical shooter. Your hands are tied by police procedure and you must follow it, such as announcing you're a police officer and using lethal force only when your life is clearly being threatened, in order to complete the missions successfully. As a result, this game is brutal. There are no quicksaves or checkpoints. If you die, you start from the beginning of the mission. That can be infuriating at times, but it forces you to be really careful about your approach to the missions and combat. For $10, this game is an absolute no brainier that any tactical shooter fan needs to try.
