Short Answer
Before launch, the most accurate wording is that Phantom Blade Zero uses connected, semi-open areas with exploration, optional routes, and side content. A final answer needs hands-on verification of region boundaries, fast travel, locked paths, and return routes.
What the Wiki Should Track
- Region names and route order.
- Shortcut loops and locked paths.
- Side quest starts and consequences.
- Boss entrances and optional areas.
- Whether late-game tools open earlier routes.
Where to Go Next
Use the maps hub for region structure, walkthrough for route planning, and side quests for optional content tracking.
