How to Unlock the Full Art Gallery

As above.

Requirements (Infirmary, Motivate)

Score 200 EXP in each category (maintenance, edgeplay, etc.) for every girl in both of their outfits.

Methods

1) Save before you knight someone. Reload to unlock other CGs with different girls.
2) Beat the game, save, reload your save, and defeat Himekami again. You will get an alternate route, one that will let you knight each girl in one playthrough.

Part 1: Prison Garb (M+E+S+T)

Part 2: Knight Outfit (A+E+S+T+M)

Aftercare unlocks after you knight someone in Purgatory (4F).

@polex411, Criminal Girls 2: Party Favors came out 5 years ago...
on the Vita.

No one knows if it will ever be released on PC.

while i did start the game for the mini games i did find the story far more interesting to the point where it seem annoying that i had to do the mini game to keep growing the girls.

also when is the second one coming out??? and don't censor its just annoying and a slander to the art of the game and its story.

You know this mini-games are the only bad thing of the game, and if i need to do 200 exp on..... 9 x 5 x 2= 90 mini-games i prefer completing the game without doing them even if the Attack lvl1 is behind the first one.

Probably. On the upside, you don't need to play that far into the game to motivate each girl in their prison clothes.

I can't remember if I completed all of them with 200 exp before knighting them... Does that mean i have to start a new playthrough?!

[Carlson]

Last I remember, those were just empty spaces. No pictures go there. Though, you can try to motivate everyone again just for the heck of it.

18 pictures, or picture number 18? You unlock the group photo (under the 'Samples' tab) by completing Ether Zone 437, if that's the one you're missing.
