Tears of Metal Secrets Guide: Hidden Weapon and Missable Unlocks

The best-documented secret in the current Tears of Metal build is Wallace’s fourth weapon. Official patch notes confirm that it has campaign-shop pieces and a reward chest; current weapon data ties the weapon to a special event; and players report that its three pieces must be collected during the same campaign.

Other equipment can also be easy to miss because its opportunity is attached to a random campaign event or timed Marathon objective. This is not a fixed-room walkthrough: the campaign map and event offers vary, so there is no reliable set of permanent coordinates to follow.

Confirmed secrets at a glance

How to unlock Wallace’s fourth weapon

Use Wallace for the attempt and plan to finish the chain in one campaign. The in-game flavor text and multiple player reports describe a three-piece set; the Steam discussion identifies the parts by their functions as a blade, hilt, and handle or pommel. The exact English labels shown by the game may differ, so match the set description instead of relying on one community spelling.

1. Start a fresh campaign as Wallace.
2. Inspect campaign-shop inventory and character-specific event rewards at every route decision.
3. Buy or claim each secret weapon piece when it appears, even if it means skipping a less important run upgrade.
4. Keep all three pieces in the same run. A failed or abandoned campaign does not satisfy the reported one-run condition.
5. Continue until the associated post-battle event or secret weapon chest resolves the set.
6. Finish the transition, return to the village, and check Wallace’s weapon selection rather than assuming the unlock failed at the reward screen.

The official July 24 patch fixed a multiplayer problem where Wallace’s secret weapon chest did not grant its reward to clients. It also stopped the campaign shop from offering a secret weapon piece after the weapon had already been unlocked. Those two notes are the strongest official confirmation of how the chain is surfaced.

Do not confuse the fourth weapon with the Flamberge

Paper Cult’s patch notes name the Flamberge and Celtic Longsword separately from the secret-weapon fixes. The extracted Wallace weapon list labels the hidden reward only as the fourth weapon. Until the game itself or Paper Cult publishes a definitive name mapping, do not assume that every community reference to the Flamberge means the secret fourth weapon.

For moves and build use after the unlock, see the Wallace weapons and build guide.

What the fourth weapon changes

Current PC-build data lists four routes for the event weapon:

These are extracted base values, not guaranteed combat damage. Emblems, Charms, difficulty, target defenses, balance patches, and whether the complete string lands all change the result.

Finding rare equipment events

Several unlock opportunities are event-driven rather than placed in a permanent chest on a permanent map. Players have reported timed Marathon chains offering Wallace equipment and other weapons. One detailed report describes failing a nine-objective Marathon despite winning the battlefield, which means clearing the normal encounter is not always enough to receive the event reward.

When an equipment event appears:

• read the event objective before engaging the main wave;
• prioritize marked objectives over ordinary enemies that are not blocking the route;
• preserve movement and a crowd-clearing command for distant objectives;
• watch the event timer separately from the battlefield win condition;
• let the reward and post-battle transition finish before leaving.

Because these offers are random, a missed reward may not return on the next run. The Castle Records can show whether an item is still locked, but it does not turn a rare event into a guaranteed next-map spawn.

Useful event choices that are easy to overlook

Not every useful discovery is a hidden weapon. Official patch notes document several named events and unlocks that can materially change a run:

• Distant Cloaks reduces Threat by 2 in the patched standard build, offsetting the Threat gained from advancing on the map.
• A Distraction uses Coins rather than Dragonstones after the July 24 balance change.
• Treasure and Dice was fixed so a winning player is not charged incorrectly.
• Tithing Box received a fix for an unlock condition that had been impossible to complete.
• Large Reliquary can no longer grant a duplicate copy of itself.

Read the current event text before choosing. These notes confirm the event behavior changed; they do not guarantee that a named event will appear in a particular Act or route.

Solo and co-op precautions

For a first secret-weapon attempt, solo removes uncertainty over who receives a shop item or chest reward. In co-op, agree that Wallace’s player will buy the pieces and open the final chest. Everyone should be on the same current branch and version.

If a client does not receive the reward, update the game before repeating the chain. The official multiplayer chest fix applies to the patched standard build, but desynchronization can still make a reward screen or inventory appear inconsistent until the next transition.

Secret weapon not unlocking

Check these in order:

1. Confirm the run used Wallace.
2. Confirm all three related pieces were held in the same campaign rather than across separate attempts.
3. Complete the associated reward event or chest; collecting pieces alone may not be the final step.
4. Let the post-battle transition finish.
5. Inspect Wallace’s weapon selection in the village.
6. Update to the current standard branch and retry if the run occurred before the multiplayer reward fix.
7. In co-op, have the host and Wallace player compare unlock state after returning to the village.

Secrets checklist

• Check every campaign shop for a Wallace-specific piece.
• Treat all three secret-weapon pieces as one-run items.
• Finish the chest or post-battle event that resolves the set.
• Read timed Marathon objectives before chasing normal kills.
• Verify new equipment in the village after the transition.
• Use the current patch before attempting the chain in co-op.

Frequently asked questions

Are there fixed secret rooms in Tears of Metal?

No repeatable fixed-room route is supported by the current sources. The documented secrets and rare equipment opportunities are tied to variable campaign shops, events, objectives, and reward transitions.

How many pieces does Wallace’s secret weapon need?

Players report a three-piece set collected in one run. Official patch notes confirm that multiple campaign-shop pieces and a final reward chest exist, but do not publish the component names.

Can I collect the pieces over several runs?

The in-game flavor text quoted by players says to find all pieces in one run. Plan a dedicated campaign rather than treating each piece as permanent progress.

Is the fourth weapon required to finish the campaign?

No. Wallace’s starting and earlier unlocked weapons all have complete combo routes. The fourth weapon adds another moveset and a high-damage full string, not a campaign gate.
