This one is called Follow Me, and it uses the song Radio Song / Superbus from the in-progress 1.60 patch. Now, the inspiration for this mission is the Pump it Up NX2 mission, Short Term Memory. If you've played that game or the Fiesta series, you know what the gimmick is. For those who don't, it's basically a complex game of Simon Says. For one measure, fake notes play on the screen showing a pattern. Then, the screen fades away, and you step the pattern you just saw in the next measure. It's easier than it sounds, and is definitely easier than Short Term Memory, since you see for a whole measure and you're only playing on single. However, the premise takes some getting used to, so it gets a level 3 out of 5.
