My first experience with tactical action FPS. In my opinion, the best of the original series. The maps and missions are all seared into my brain forever. I remember spending hours just in mission planning, refining routes for the different teams and evaluating different room breaching and clearing strategies. Nothing compared to the sweaty anxiety as I'd be at the end of a mission, too afraid to start the assault on the final room filled with hostages and their armed captors. I remember falling out of my chair when I got one-shot, so many times. This game would be a huge win for GOG, especially with functional multiplayer.
