Mortal Shell II Walkthrough: Spoiler-Light Route

Treat Mortal Shell II as a flexible progression journey rather than a single mandatory route. Complete the tutorial, acquire an early Shell and useful equipment, then explore whichever branch of the compact interconnected world matches your current strength. Some main bosses can be encountered in different orders depending on the areas you visit first. Your overall objective as the Harbinger is to reclaim the Undermether’s stolen eggs. Exploration is part of progression: wandering can reveal additional Shells, story material, weapons, upgrades, curiosities, and more than 80 dungeons. Evidence for this answer is linked through official site and PowerPyx.

Handle the tutorial Tar Golem carefully

The Tar Golem is the first main boss and appears at the end of the tutorial. The encounter is designed to end in defeat, but reducing its health to zero first awards the “No, You Still Can’t Win” trophy or achievement.

This fight occurs only once during a playthrough and does not return in New Game+, making that achievement missable. Fight patiently and chip away at the slow boss; if an attempt deteriorates, the cited guide says quitting to the main menu places you before the Bone Gate when the save is reloaded.

Collect an early Shell before committing upgrades

For Tiel, begin at Widow’s Overlook and travel southeast. The cited Shell guide says you can run past the enemies, interact with the coffin, and spend one Glimpse to unlock Tiel’s initial memory so skill-point investment can begin.

For Proxima, travel north from Widow’s Overlook, circle around Blackridge Cliffs, climb the hill, and enter the small cavern. The guide reports that she can be unlocked without fighting enemies. It also advises concentrating limited Glimpses on one or two Shells; because that video used an earlier test build, confirm exact progression costs in the current version before making irreversible choices.

Add a melee weapon and sidearm

One documented early melee option is Axe and Dagger. From Mushroom Village, cross the bridge to the right, reveal the illusory archway, pass through the statue, collect the key, return to the Shrine of Trials, and complete the shrine to obtain the weapon.

For the Forgotten Crossbow, locate the Flooded Village dungeon north of the Blackridge Pass beacon and pass through the illusory gate at its entrance. Inside, head north across the rooftops for the Damp Key, then use it to open the chapel. Do not expect every sidearm to be this direct: several require off-route exploration or difficult boss encounters.

Evidence: Esoterickk boss chapters.

What to do when progression stalls

Leave the difficult route and explore another area. The open world is designed for free exploration, and a gameplay reviewer specifically recommends changing destinations when enemies or a boss become a wall rather than assuming you must clear that encounter immediately.

Use the vendor’s maps for broad hints about Shells and weapons, but expect vague directions rather than exact markers. Search branching paths, hidden structures, and illusory entrances, and remember that a recommended boss chronology is not necessarily the only valid order.

What to verify after a game update

Treat this mortal shell ii walkthrough page as a dated route, not a permanent promise. Store wording, balance, availability, and progression details can change after patches. Recheck official site, PowerPyx, Esoterickk boss chapters when a later build conflicts with the steps above, and prefer the newest first-party statement for release or platform facts.
