Rainbow Six PC

Tom Clancy's Rainbow Six is a classic Clancy-style story where you lead an elite multinational task force battling international terrorism in highly realistic settings. Game play is organized around a series of missions in which you must plan and execute precise assaults on terrorist installations. As your mission advances, you uncover a larger and more sinister conspiracy, where the fate of the world hangs in the balance. And unlike other games, if you make a mistake, you're gone--because in the real world, one shot counts.
