Harmagedon

Harmagedon was a collaboration between HyuN and lixound (the latter being the same person behind the alias Ryazan) and one of the winning entries at the 3rd PIU Creation Contest. Its first appearance was in Pump It Up M, the mobile entry, before it was folded into the arcade with the 2.06.0 update of Pump It Up XX on April 8, 2021. In XX it could be unlocked by buying it for 128 Gold Shoes. The male voice sample that opens the song appears to be taken from the radio audio in the playable teaser for Silent Hills.

During the Pump It Up M phase the eyecatch and teaser portion were handled by Lyrebird Ferdinant. After that artist stepped away, the final BGA was made by Irelriser, credited under the alias AREMOS (the same name used on the visuals for Daydream in EZ2AC). By the creator's own account, the goal was to convey an apocalyptic image; because the theme draws on biblical passages, a book was chosen as the central motif and the piece was built as a framed, story-within-a-story composition.

In PHOENIX it carries Single charts at S4, S6, S10, S16, S19 and S22, plus Double charts at D13, D21 and D24, all designed by SUNNY. The S22 is rated low within its level: much like the CROSS†OVER S22, the difficulty concentrates in the closing run, with an early one-foot fixed section where it is easy to get tangled. Conserving stamina until the decisive stretch is the smart play. The highlight run mixes plain bursts, runs that demand twists, and a siderun capped by an axis-tap, though its twists are gentler than those other 22s ask for; even so, a 2+1 trill and a bracket-laced run remain at the very end. The D24 is a fairly honest high-speed 16th run with mild twist angles; the trap is a sudden staircase inside the densest section, where keeping your balance centered is key.

In Pump It Up XX, the 1.49 patch reworked the S19 and S22 charts. The visual credits also differ by version: AREMOS and Ji Eun Choi on the PIU M line, and Lyrebird Ferdinant on XX.
