I would like to collect all the requirements for the "plunge into URA" sections on each level. The general condition is to finish story mode once. For the rest, it seems any difficulty should do. Thanks to everyone for helping in the comments, we've completed the URA requirements list. I have put up a guide as well, if anyone wants to be mentioned there, please let me know....

I only played Overdrive for a short period of time, so I don't know how to unlock them. Are they random drops or are they in specific secret places?

Hey there. I downloaded the demo and really want to try it out, but nothing seems to be working. The intro plays and afterwards, mouse, keyboard, controller, nothing seems to be doing anything. Any ideas?

Anyone know what the crown icon on difficulty selection means? I have one next to "EASY". I don't think it was always there. I never noticed it until after clearing nightmare.
