Maybe you’d have thought that the tension might drop out once you’d devised a perfect strategy, but not so. Just like real life, some of these terrorists are smart - performing flanking maneuvers of their own. And to make things worse, every time you reload a checkpoint, the enemies respawn in different places making their movements highly unpredictable. It’s this simple feature that adds incredible replay value to the game’s online Co-op modes. You never get bored.
If Rainbow Six has any major weaknesses, it’s arguably in its similarity to Ghost Recon Advanced Warfighter 2 and in an underwhelming storyline. Depending on how you feel about Tom Clancy plotlines, you might not be too surprised that it revolves around eastern-European terrorists, a scheme to blow up the US and something about Mexico. There are no cutscenes to speak of, because all the storyline is relayed through a small window on your HUD. Maybe it’s for the best though, because this game is more about action than words.
