Hi Katerchen,
I don't have Mega Step Blast, but I do have IMAX. I have done the tape about a few times and I feel most the moves are pretty basic. I think a few things for me were hard to catch at first, but it shouldn't take long to learn any of the steps your unfamiliar with. It is a very intense tape, and I can't do it all the way through w/o rests. Especially the end where there are a lot of jumps. I hope this helps. If you click on the IMAX tape on the home page you can scroll down to the bottom right and look at Video Fitness reviews of the tape, they're usually very descriptive. And I think College Video gave this a moderate rating for choreography. Good luck!
