Rainbow operatives take to the chaotic streets of Las Vegas as an escalating terrorist siege in "Sin City" threatens to take world terrorism to new, uncontrollable heights. The future of global security hangs in the balance as you battle to defend classic Vegas locations and environments like Fremont Street, the Strip, and casinos.

Experience Las Vegas like never before - through revolutionary next-generation technology as you work against the clock to keep one of the world's most recognizable cities from utter devastation. The Rainbow Six series goes back a long, long time as the first installment was released back in 1998, and was strictly meant for PCs. Later on, Red Storm Entertainment ported the game onto other platforms including Nintendo 64, PlayStation, Mac and Dreamcast.

If that's the case and you want to know exactly what to look for when it comes to this game, we have prepared a full list of unlockables for you. Good luck!
