Shells are the first system to map.

The official store description confirms the system’s shape without giving us a complete public roster. That is enough for a useful overview and a clear research backlog.

What is confirmed

The Shells belong to eight lost warriors and are scattered throughout the ravaged world. The player can seek and possess them, use their innate abilities and discover each story.

What needs an in-game source

• Exact Shell names and locations.
• Ability descriptions, costs and upgrade paths.
• Which Shell fits a specific weapon or encounter.
• Any ranking, “best Shell” or numerical comparison.

Research note: a clean overview is already useful. It gives future location pages a stable definition without pretending the roster is verified.
