A compact, interconnected world
The official Steam and Mortal Shell descriptions present a connected open world built for free exploration. The main route is described as the golden path; detours can reveal Shells, weapons, upgrades and story material. That does not make every side route safe or establish an unrestricted route after the tutorial.
What the setting includes
The PlayStation description identifies ruined temples, forests, icy graves and bone citadels. These are setting categories, not a complete named map or a recommended completion order.
What to look for while exploring
- Shells: eight playable warriors are confirmed; see All Shells
- Equipment: inspect the weapons and upgrades you discover before spending resources
- Story clues: note the scene or item behind a theory; see Lore
Eight Shells does not mean eight Sidearms. We have removed the unsupported Sidearm count and the former region/boss sequence from this overview.
A practical navigation habit
Note your last named landmark, choose one unexplored branch and record where it reconnects. Keep locked passages separate from routes you have actually cleared. This is general navigation advice, not a claim about an in-game quest log or map feature.
For a named Beacon index and early route details, see Locations and Beacons and Game Progress Route. Those pages identify their community-guide sources; their route details are not derived from this official overview.
