Remember that Tae-Bo craze in the 90s? You know, you bought the videos, worked out once and then would just watch them while eating chips?

You might think you're a pro this kind of thing in games, but you need some bodily dexterity too. This is one of the most physically challenging virtual reality games we've played yet.
