Tom Clancy's Rainbow Six is a tactical shooter computer game and the first installment in the Tom Clancy's Rainbow Six series of video games. Rainbow Six focuses more on stealth and tactics than on sheer firepower. To add to the realism, all in-game characters, terrorists, hostages and Rainbow operatives, can be wounded or dispatched in just a second. Tools such as thicker body armor, automatic rifles, and grenades have little value before the player grows accustomed to the gameplay.
