Helpful Info

Sounds metal! I found this to be deceiving due to the 11-notes you'll have to rush through and the zig-zag track + click note patterns that follows with rush notes is a pain... But I did 3 MMs on this song in a row...? Something really random, depends on which day it is to get the click + drag patterns.

This is one of my favorite songs in cytus. The tempo is very straight-forward, therefore it is very easy to get a good TP. Get rid of all the patterns and you will succeed.

This song has a relatively quick scan line, and at the front part, beware of the 2,1,2,1,2 tap chart. And at the end, it gets really messy. So study the chart.
— MrGZJcool
This is very likely the hardest song in Chapter V. It has a fast scan line, so be prepared.
— SerialNo30000324
Those vibes though. The scan line is pretty fast, so make sure to time those double notes well. Prepare yourself for a triple note somewhere.
— DSZ9
My worst enemy.... Alternating double notes.

In easy mode, near the end of the song, note that there is a hidden note in the 4 grouped notes. The only note groups I despise were the 2-1-2-1-2 and the zigzag slide-taps. I mastered it already.

I loved the Cover Art, But hated the Chart, So Hard
— SuperK2
The last song in Chapter 5 that I MM'd. Despite that, I love the metal feeling of it, but I also hate the zigzag & rapid clicks near the end... Oh, and don't forget the compact note 2-1-2-1-2-1-2 in the beginning, they're a super effective killer!

Short, but dangerous.
