I played this game a shit ton as a kid, and I can't get over the fact that it released little over a month before the American invasion of Iraq in 2003. IIRC, the first American mission features a cutscene of tanks running over the Victory Arch.
The storyline revolves around America and the PRC fighting a witldwide terrorist front called the "Global Liberation Army".
This game was so much fun, full of propaganda but it was so on the nose it was sort of comical to me. The zero hour expansion and the mods were great too
