It was in production for almost 2 years before Ubisoft decided to release it as a free download for FilePlanet subscribers on June 9, 2005. Developed by Ubisoft-Casablanca, this latest expansion features a 7-mission campaign in which Rainbow neutralizes a terrorist nuclear bomb threat, 3 classic missions, 8 new multiplayer maps, 6 new weapons, as well as 5 new multiplayer game modes.
