While Tom Clancy's Rainbow Six: Lockdown isn't a bad game by any means, there's a good chance that it might disappoint many of the series' longtime fans. One of the best things about the earlier games in the franchise was the feeling that you could be taken out at any time by a hidden terrorist, which made player approach each situation much more carefully. With the addition of the heartbeat sensor, you can simply scout out every room before you enter, allowing you to easily pinpoint enemy locations. Although the single-player game is lacking, the same thankfully can't be said about the multiplayer, which is just as strong as ever. Maybe next time Mr. Clancy should skip the storyline and just let players battle it out for online supremacy.
