Your going to need a lot of space for this (well I did). Its mostly like one of the dance mats at the arcade or at home of Dance Revolution where you have to hit the certain tiles. You have a 4x4 square and the tiles get lit up on the floormat as well as the screen of the board, to win you have to get 4 in a row by using your feet to hit the tiles that light up before your opponent does. Can also get this achievement if you hit the first four in a row.
