I haven't even gotten the game yet (I chose slow, cheap shipping so it should be here probably next week...) but I was checking the PD wiki to read how to unlock the modules, and I have a few questions about some of them so I can be sure when I do get to play the game. 1. When it says "clear x amount of songs using x Vocaloid", does that mean I have to play different songs, or will playing one song over and over work? For example, if I had to play 39 songs using Miku, would it count as 1 play if I played Kagerou Days twice or three times, or would it count as 2 or 3 plays? 2. Would using help items nullify the achievement of an objective? For example, if I used the help item Safety Judge to clear the objective of "clear Erase or Zero with 0 notes in at least one of the note ranks (i.e. Sad, Fine, Worst, etc.)", and I did get 0 notes thanks to the help item, would that count and unlock the module even though I used a help item? 3. Like my second question, would using help items while also using a challenge item still unlock the module? For example, if I used the Panic challenge item in Destroy Destroy, but I used the Recovery help item at the same time since you can use up to 3 items, would that still count as me clearing the song with the challenge item so the Scarlet module will unlock? Or would it not count because I used a help item with it? (Can you even combine help and challenge items together?)
1: It would count as multiple plays (for example...to get Kaito V3 you have to clear 50 songs with him...there are only 40 songs in the game however) so, if you wanted you could play Kagerou days 39 times in a row and as long as you achieve a standard or greater each time they'll each count. But, if you were to choose a duet or trio song and you set Miku in both places...it would count as one use of her not two or three. 2: I don't think so, but I don't really use help items so I can't guarantee anything 3: No, you can't combine help and challenge items, sorry.
Help and Challenge items do not effect unlockables (except of course if one REQUIRES a challenge or help item). EDIT: Wait! With your example, using an item like Safety Judge wouldn't work as you need to CLEAR the song for you to get the item I believe. That help item gives you a cheap no matter what.
^ Oh, really? I looked at the items on the PD wiki and it didn't say anything about a rank being forced. My bad. Anyway, thank you guys for the answers! I'm a little more relieved now.
