A somewhat-annual event in which participants create steps for original songs for use with Dance With Intensity (DWI), and to a lesser extent, Stepmania, computer simulators of Dance Dance Revolution. Alternately known as TM.
Somebody entered steps for a Linkin Park song in the last TournaMix.
From Dance Dance Revolution (a.k.a. DDR); One More Extra Stage. "Dance Dance Revolution" (the name is the title of the OMES song, as well as the game itself.) The song is played with modifiers Dark (visual landmarks for timing are invisible), Reverse (the arrows, normally scrolling from the bottom-up, now scroll from the top-down), 1.5x (the arrows scroll 1.5 times faster than usual), and Sudden Death (one No Good/NG or non-combo step (good, boo, miss) ends the song).
Acquired by getting a AA on the default Extra Stage song The Legend of MAX, which is played using modifiers Dark, Reverse, 1.5x, and No Recover (the life bar, which usually starts at about 1/2 full and grows with the player's score, starts at full strength, and the player cannot add to this bar; only lose from it).
