From PS Blog: “For decades, Team Rainbow has shielded the world from some of the worst threats imaginable. Terrorist threats, biological weapons, and the threat of nuclear war have all been averted thanks to the elite operators in the Rainbow program.
This January, we face the greatest terror our world has ever seen: a lethal, mutating alien threat. Rainbow Leader Ash has recruited an elite global team of Rainbow Six Operators best suited to the task to form REACT (Rainbow Exogenous Analysis and Containment Team).”
