Any achievement related to achieving (X) amount of FULL COMBO / PERFECT GAMAE / NO MISS / specific grades like A / AA / S / SS / SSS / can only be gotten in Division mode. WARM UP will not help here.

you literally have to make an A / AA in those levels, not an S or higher. (I know its kinda hard but you can try a song that you know you CANT get an s, it will help!)


I'm guessing you made this face when you tried to play them.


And it's no wonder. These two levels have a particular mechanic called
"gimmicks".
Did you see how the keys move? It's not a programming error, and the game is not badly made (maybe with one or two levels it was, but that's not the case). Gimmicks are just that: special visual effects that make our experience more "lively" (i would say fun but is a big word to describe it).

These two levels in particular are among the most difficult in the game due to their mechanics.

Ugly Dee

Break It Down



to help you achieve these achievements,
I'll give you all the tips I can about both.

Ugly Dee is a freeze-frame where all you have to do is watch the approaching keys and HOLD THEM pressed until the next key hits the beat of the song. I'm leaving a video of someone playing it so you can better guide yourself. I highly recommend practicing it in WARM UP and not relying on putting an arcade gameplay on top of it to guide you because, as I clarified before, the CHARTS changed for the R!SE version. Therefore, the Arcade CHARTS are different, and it's impossible to try to beat it by putting the arcade chart on a cell phone while playing R!SE.

Break It Down is similar to Ugly Dee. You have to follow the rhythm of the song and press the keys as the song progresses, and fortunately, you don't have to hold them down. The bad part is that instead of being a SINGLE, it's a H.DOUBLE. To try this, you must first familiarize yourself with H.DOUBLE keys, playing progressively from H.DOUBLE 12 to H.DOUBLE 20.
i recommend [SDF][JKL] to play these kind of levels.
Once you have the full theory of how to play H.DOUBLE, we move on to practice. Just like with Ugly Dee, I recommend using WARM UP to practice.
Again, I'm leaving you a video tutorial of someone playing it.

Im NOT wish you luck because I KNOW you'll be able to do it!!!
The more you play it, the more you'll master it!

¡Thanks to LIDLiLi for the idea!

Some songs are locked and unlock when you level up. To complete all the achievements, you need at least level 96.
Here's an ordered list of the songs you'll unlock, provided by our good server Reiden2.
(Thanks to Reiden2 to make this list!)

Lv.11「Tales of Pumpnia」SINGLE 17
Lv.18「Emperor」SINGLE 16
Lv.28「Mr. Larpus」SINGLE 22
Lv.60「Shub Niggurath」H.DOUBLE 18
Lv.67「Ugly Dee」SINGLE 17
Lv.79「Mad5cience」SINGLE 20
Lv.85「Avalanche」H.DOUBLE 19
Lv.91「Utsushiyo No Kaze feat. Kana」SINGLE 17
Lv.96「Red Swan」SINGLE 18


Don't worry, not everything can be achieved in a few hours. It's all about dedication and time to understand the game. As a player with almost 150 hours of experience, I recommend playing S1 to S5 songs and not missing a single one. SSS scores give us tons of experience, and even more if we manage to get a NO MISS or a PERFECT GAME. So if you want to "farm experience," I recommend starting from the beginning, have fun and pump it up!
¡And take it easy because before you know it, you'll reach level 100!
