Route / 01 / FIELD NOTE
Mortal Shell 2 Walkthrough: Fainweald First, Then Mammon
The launch route opens from Marrowkeep: clear Fainweald gates first, then use the keep siphon to open the later Mammon path.
The campaign spine
Complete the prologue, establish Marrow Keep, recover Ova through six Corrupted Gate dungeons across Fainweald and Mammon, clear the three Unfound Path branches, then defeat Zmey the Unbidden. This is a flexible route order rather than a claim that every optional room has one mandatory sequence.
Prologue and Marrow Keep
Use Harros to learn Break, Riposte, the equipped Seal and the Foundling recovery state. Once Marrow Keep opens, identify the Shellkeeper and Tarforge, activate nearby Beacons, choose one primary Shell and weapon, and avoid spreading early materials across experiments you will not use.
Fainweald gates
Fainweald contains Glutted Mire, Sanguine Caverns and Prisoners’ Domain. Their bosses test movement, grab recognition and repeated wide swings. Each major victory provides Ova through its Beacon; return to the keep to spend points, inspect Shell routes and check new dialogue before forcing the next gate.
Mammon and the Unfound Path
Mammon’s progression dungeons are Conquered Temple, Withered Shoals and Faded Citadel. After enough Ova, the Unfound Path opens three branches: Bridge of Procession, Obsidian Vault and Faithful’s Shelter. Clear all three, take Endless Core from Hidden Nave when practical, then prepare for Zmey’s Cosmic Disease and area attacks.
Cleanup before Send Ova
Defeating Zmey does not force New Game Plus. Remain in the current cycle to collect Shells, weapons, sidearms, Tarstones, Beacons, keys and optional NPC scenes. Choose Send Ova at the Gloom Siphon only after the cleanup list is complete.
