All Mortal Shell 2 achievements and how to unlock them

Unlock requirement: Claim your first Shell, Weapon and Sidearm. All three categories must be represented; obtaining only a Shell or weapon does not satisfy the full condition.

Unlock requirement: Enter the Festival. Entering the named event is the complete condition.

Unlock requirement: Reach Marrowkeep. No additional collection or combat objective is stated.

Unlock requirement: Complete Mortal Shell II. This is the main story-completion milestone, separate from the broader achievement-set requirement for No Lifer.

Unlock requirement: Unlock Proxima. This individual Shell unlock also advances Shell Seeker.

Unlock requirement: Unlock Lazlo. Record Lazlo on your Shell checklist when the achievement appears.

Unlock requirement: Unlock Tiel. The trigger is the Shell unlock itself.

Unlock requirement: Unlock Gragu. Keep Gragu on the same collection tally as the other named Shells.

Unlock requirement: Unlock Smert. Finding a related objective is not a substitute for completing the unlock.

Unlock requirement: Unlock Sester Genessa. Once triggered, count the unlock toward the complete Shell collection.

Unlock requirement: Unlock Sariel. Sariel is another checkpoint on the path to Shell Seeker.

Unlock requirement: Unlock Eredrim. The achievement does not state an additional equipment or combat condition.

Unlock requirement: Unlock all Shells. Review every individual Shell unlock before treating this collection as finished.

Unlock requirement: Unlock the Cursed Child. Add the Cursed Child to the weapon checklist leading to Lord of War.

Unlock requirement: Unlock Great Martyr’s Blade. Obtaining this weapon advances the all-weapons objective.

Unlock requirement: Unlock the Salvaged Trebuchaxe. Remove it from your checklist only after the unlock triggers.

Unlock requirement: Unlock the Veteran’s Battle Axe. This is one of the individual weapon conditions supporting Lord of War.

Unlock requirement: Unlock Axe and Dagger. Treat the full item name as a single weapon unlock.

Unlock requirement: Unlock the Axatana. Count the Axatana toward the complete weapon set when the achievement appears.

Unlock requirement: Unlock the Clockwork Scythe. This unlock contributes directly to Lord of War.

Unlock requirement: Unlock Black Needle. Add Black Needle to the same tally as the other named weapons.

Unlock requirement: Unlock the Obsidian Hammer. Obtaining the unlock advances the complete weapon collection.

Unlock requirement: Unlock all Weapons. The individual weapon achievements provide useful checkpoints, but the condition covers the entire weapon collection.

Unlock requirement: Unlock the Triarch Repeater. This sidearm contributes to Guns. Lots of Guns.

Unlock requirement: Unlock the Forgotten Crossbow. Record the unlock on your sidearm checklist when it triggers.

Unlock requirement: Unlock the Ballistazooka. The sidearm unlock itself is the complete condition.

Unlock requirement: Unlock the Caged Hystrix. Count it toward the complete sidearm collection.

Unlock requirement: Unlock all Sidearms. Check every individual sidearm unlock before beginning wider cleanup.

Unlock requirement: Defeat The Nameless Captive. Peter’s Perfect Parry adds a separate execution challenge to this encounter.

Unlock requirement: Defeat Droeg, the Conquerer. No particular weapon or finishing method is included in the condition.

Unlock requirement: Hidden achievement. The named boss defeat is the full requirement.

Unlock requirement: Defeat Orrem, the Reclaimed. This is a direct encounter-completion achievement.

Unlock requirement: Defeat The Lost Child. No additional challenge modifier is specified.

Unlock requirement: Defeat Sir Isaac, the Scholar-Prince. Add this encounter to your cleanup list if the achievement remains locked.

Unlock requirement: Take the Tar Golem to his Minimum Health. Follow the health condition literally; the achievement does not ask you to defeat the Tar Golem.

Unlock requirement: Parry each one of The Nameless Captive’s headspins. This is distinct from simply winning the encounter.

Unlock requirement: Defeat The Monolith. No separate collection objective accompanies the defeat.

Unlock requirement: Defeat Hexapod. Track this as an encounter achievement rather than an exploration collectible.

Unlock requirement: Defeat Malborn Offspring. No special damage type or equipment condition is stated.

Unlock requirement: Defeat Magdalena, the Lady of the Woods. The named defeat is the complete requirement.

Unlock requirement: Collect all of the Ova. Keep a dedicated Ova tally because the objective requires the entire set.

Unlock requirement: Find all Map Fragments. Check your explored areas for missing fragments before moving to encounter cleanup.

Unlock requirement: Cleanse All Beacons. A Beacon leaves the checklist only after it has been cleansed.

Unlock requirement: Find all Tarstones. Track Tarstones separately from Map Fragments and Ova.

Unlock requirement: Watch your first Shell Memory. Watching one begins the memory-related achievement path.

Unlock requirement: Watch all Shell Memories. Finding a memory is insufficient if it has not been watched.

Unlock requirement: Play all Lute Tracks in the Game. Keep played tracks separate from tracks you have merely encountered.

Unlock requirement: Reach the maximum bonding tier for a Shell at the Shellkeeper. Concentrating bonding progress on one chosen Shell directly serves this condition.

Unlock requirement: Max out a Weapon at the Tarforge. Focus your Tarforge investment on a chosen weapon until it reaches its maximum state.

Unlock requirement: Discover the secret of the Mango. Keep this as a separate secret objective when reviewing unfinished achievements.

Unlock requirement: You’ve mastered nothing and this is your reward. Pretty pointless, eh?

How to unlock: Baghead asks you to fetch him something “special” and rare, and every item you can actually carry is the wrong answer — handing over the Special Moonshine gets you turned away. Return to him empty-handed instead, because the whole joke is that he values doing nothing. He then offers to make you his successor. This unlock is named Bag Holder on PlayStation and Baghead on PC, so both names refer to the same reward. Full route: Baghead location, requirements, and Bag Holder trophy guide.

Unlock requirement: Cause Egon to pass away. This concerns the named outcome involving Egon rather than a generic boss or equipment milestone.

Unlock requirement: Unlock All Achievements for Mortal Shell II. Complete every progression, collection, encounter, challenge, memory, upgrade, and bonding condition to finish the set.
