You've collected all of the special coins, completed all of the levels twice, pulled down the golden flag at the end of each course, and rescued the princess. What else is there to do in Nintendo's Super Mario 3D Land for the Nintendo 3DS? As these special Super Play Movies from the company show, a whole lot. Nintendo is showing off secrets in these compilation videos that reveal the location of warp zones, shortcuts, infinite 1-Up spots, speed running tactics, and other neat tricks and tactics to try across the Mushroom Kingdom (all three dimensions of it). There's some neat stuff happening here that I can't wait to try for myself. Be sure to bring your Tanooki tail when you give these secrets a shot. You're going to need it.
