OnlySP: Back in its heyday, the Rainbow Six series was the king of tactical shooters. Nobody did realistic, open-ended and challenging shooter scenarios quite like that series did. When the current console generation arrived, the series made a trip to Vegas, and since what happens there stays there, it decided to experiment with third-person cover shooting with successful if slightly forgettable results. After a retread of that scenario in the form of Vegas 2, the series went on a temporary hiatus much like Ubisoft’s other Tom Clancy franchises, Splinter Cell and Ghost Recon. Like those games, it was inevitable that Rainbox Six would soon come back in slick, rebooted form sooner than later.
