I've been waiting for this to come to GoG for a long, long time. I cannot recommend this game highly enough. More accessible, and definitely more forgiving, than the first two Rainbow Six titles, SWAT 3 forces you to think about your environment and rules of engagement. There are some quirks to the AI behaviour that often lead to a different experience when replaying a level. Directing the Team AI is fast and accurate. They can occasionally leave themselves exposed to a crazed gunman bursting through a door, but that only serves to keep you, as the player, alert to threats from all angles. Taken online with the right people, it's a wonderful game to role-play. Each member of the fire-team fulfilling a role with the odd tactical mistake forcing the team to adapt and make good. The later levels can be very tough to complete, the LA Convention Centre being a personal highlight. Stick with it though and it will reward you with, literally, years worth of re-playability.
