All 13 Illusory Walls and Hidden Paths in Mortal Shell 2

The Mortal Shell 2 world map marks 13 hidden paths: six hidden walls, two hidden wall switches, two markers typed Hidden Path, two secret pipes and one breakable ceiling. Open the Hidden Paths layer to see the whole set, every position verified on LootMap’s interactive map. Eight of the 13 sit at or north of the Marrow Keep on the Fainweald side, five south of it through the Ruins of Mammon, and they run from a hidden wall at the map’s northern edge down to a secret pipe on Sariel’s shell site in the deep south.

Players call these illusory walls, borrowing the Dark Souls term; the layer’s own name is Hidden Paths, so both words point at the same 13 spots. Player reports say Tarstones turn up behind illusory walls. The world map carries one Tarstones marker, a few steps north of the Boss Arena in northeastern Fainweald, and it does not sit at any of the 13 hidden paths, so the map cannot point you at the Tarstones those reports describe.

Six hidden walls

Two of the six sit almost on top of a chest marker: the one above Genessa’s shell site and the upper of the two deep-south walls. That pairing is worth remembering in reverse: when a chest marker looks like it is inside solid rock, check whether a hidden wall marker is sharing the spot.

The wall inside the Marrow Keep is the one players were already talking about before release. Player reports say there is an illusory wall in the hub, and this is the marker the map puts there, a few steps northwest of the Marrow Keep marker and right at the edge of the seven Locked Shell markers.

Two hidden wall switches

The northern switch sits a few steps west of the Crypt Key Door, with a chest a few steps southwest of it. It is also the closest hidden path to that Tarstones marker, a short walk northeast.

The second is the one hidden path with nothing collectible right beside it. The nearest pickup is a coffin a few steps northeast, and a Lift Call sits a short walk northwest. Steer by the Wormfish Exchange, a short walk to the north.

The two Hidden Path markers

Both of the plain Hidden Path markers sit beside something you were going to collect anyway. The northern one sits a few steps southwest of the Forgotten Crossbow sidearm and a few steps north of the Forest Map Fragment and the map station it shares a spot with.

The other sits a few steps northwest of the Chapel Key pickup, with Tiel’s shell site the same short distance southwest and a Door marker just north.

Two secret pipes

Both secret pipes are in the far south, a short walk apart. The lower one sits a step north of Sariel’s shell pickup, so anyone running the shell checklist walks past it.

The upper pipe sits in the stretch of Galvanic Shard nodes and Stone Statue enemies northeast of Sariel. The Healing Charge Chalice at the Tar Root Gate is a short walk east of it.

The one breakable ceiling

The single Breakable Ceiling marker sits in the northwestern forest clearing. Eredrim’s shell pickup is right beside it to the east with its Shell Unlock marker on the same spot, a loose Glimpse sits with them, 20 of the map’s 54 Spoiled Ovum markers ring the clearing, and a Healing Power Chalice is a step west.
