NIS America announced earlier today that the Criminal Girls sequel will be landing on North American shores on September 20th, for the PS Vita.
The sequel expands on the mechanics and story of the original Criminal Girls: Invite Only, as well as introduces a new lineup of characters for the game. Party Favors, also introduces a new skill tree mechanic, which allows you to level up the girls along the…ahem…. S and M paths.
You can read more about the game, and even Pre-Order the limited edition, on the Criminal Girls 2: Party Favors page
As is the case with many imported titles, there are some changes and revisions that need to be made, before the game can be released in the U.S. NIS America published a blog post, detailing many of those revisions and why they had to be done. You can read the blog post about the changes here.
