I’ve seen a few methods for unlocking Juri, but they all rely on swapping another character out, and most are also buggy and can cause game crashes, so I made my own, better version. It replaces the random character select option with Juri, and will let you select both Urien and Juri for the same match if you like. Enjoy :).
Capcom have said they will ban people that use Urien or Juri online. I really don’t think they have the ability to detect it, but still, I don’t advocate playing as her online until the official release.
