Zenless Zone Zero Billy Mindscape Cinema
Unlocking Mindscape Cinema levels in Zenless Zone Zero requires you to pull duplicates of an Agent. They provide powerful upgrades for a character but aren’t necessary to clear content. Since Billy is a free character, however, you'll naturally be one step closer to getting all of his upgrades.

Zenless Zone Zero Billy Materials
If you plan on tackling Zenless Zone Zero endgame content, you’ll need to raise the levels of your characters and enhance their abilities. You’ll need the following items to do that with Billy.
- Physical Chips (skill enhancement material)

These materials can be obtained by doing Combat Simulation Training at the HIA Club. You might also be able to find some of these items for sale at the 141 store so be sure to check what they have available at least once a week.
How to Get Billy in Zenless Zone Zero
You will automatically unlock Billy shortly after starting the game. However, you can earn additional copies of Billy to upgrade him in either the standard or event banners. As an A-Rank character, although it's more common to get them than an S-Rank, it's not possible to narrow down your search. Eventually, though, you're bound to get another drop of Billy.
