Team Rainbow is a multinational task force comprised of counter-terrorism experts from around the globe. Equipped with state-of-the-art weapons, Team Rainbow is deployed during terrorist crises. When all other attempts have failed, Rainbow is brought in to save the lives of innocent people. They do not negotiate with terror. They destroy it.

Members of the team are from all over the world, the best of the best, and you are one of them. You start out rescuing hostages from terrorists, but as you go on, you discover there are bigger things at stake. Such as the entire world.
