Dungeons of Hinterberg now has 50 achievements: 41 in the base set and nine added with New Game+. Finish the dungeon, coin, relationship, equipment, exploration, and cumulative work on Luisa’s open map before entering Wassermann’s Arena. Then carry that clean save into New Game+ and target the nine update achievements without rebuilding more than necessary.
This route is scoped to Luisa’s main campaign and New Game+ as verified on August 4, 2026. Episode Renaud is a separate prequel selected from the main menu and is not part of this achievement route.
Take the Beginner coin, but use the patched recovery if you missed it
In Beginner’s Dungeon, go up the opening steps and through the gate. After Klaus calls out, continue forward and climb the ledge on the right to collect the dungeon’s Commemorative Coin. Taking it here is still the fastest route.
Older completion advice calls this coin permanently missable because the tutorial dungeon cannot be revisited. That warning is no longer the whole story. The first official patch added the missed Beginner coin to the Souvenir Shop, specifically so Collector remains obtainable. If the Beginner entry is blank later, check the shop before abandoning the save or starting over.
Use the Stamp Book as the detector for the rest of the run. The updated book marks which Commemorative Coins are already collected. A completion stamp and a coin mark are separate checks: after each dungeon, verify both before moving to the next region.
Spend evenings on the unlocks the achievement run needs
Do not spend every evening solely on the character whose story you like most. Several relationship rewards unlock systems required by the base achievements, and one reward speeds every relationship that follows. Prioritize the following breakpoints while also progressing the story quests that make those characters available.
| Character and level | Unlock | Why it belongs early | Failure check |
|---|---|---|---|
| Alex level 4 | Faster relationship level-ups | Reduces later evening investment and helps the three-friends and completed-relationship goals | If progress feels unchanged, confirm Alex has reached the fourth reward rather than merely the Friends label |
| Kai level 1 | Additional Attack Conduit slot | Directly supplies the third slot required by Unlocking Potential | If the achievement stays locked, open the conduit loadout and confirm the new slot is available |
| Renaud level 1 | Combo Counter | Directly supplies the system required by Dance of Death | If there is no counter in combat, the first relationship reward has not been applied |
| Hannah levels 1–3 | Attack Conduits, sword enchantments, then armor upgrades | Opens the routes for Virtuoso, Enchanting, and Tough and Buff | If a shop action is missing, return after reaching the matching relationship level |
| Thea level 1 | Locked treasure chests | Needed before sweeping Hinterwald’s locked chests for Grove Trove | If a red chest remains locked, advance Thea rather than searching for a dungeon key |
| Travis level 1 | Photo Mode | Becomes useful again in New Game+ for the outfit selfie | If the camera option is absent, complete Travis’s first relationship level |
| Klaus levels 2–3 | Goo removal, then another Charm slot | Supports equipment cleanup and the packed Charm-stack requirements | If goo-covered gear cannot be cleaned or the Charm stack is too small, check the corresponding reward level |
For Friendly Overtures, bring any three people to Friends. For Heart to Heart, finish one entire relationship. Keep Social Butterfly separate: its detector is Alex’s notes, and it requires meeting everyone listed there, not merely raising three relationship bars.
Clear 26 dungeons without losing the collectible thread
The completion set covers 26 dungeons and 26 Commemorative Coins. The apparently secret total matters: Hinterberg publicly presents 25 tourist dungeons, while Toxic Archipelago is the hidden real dungeon behind the investigation route. Do not use the tourist count as your completion counter.
- Before entering: note whether the dungeon is new and whether Luisa is tired. Reserve one uncleared dungeon for Running on Fumes.
- Inside: activate the Waystone when one is available. Collect the coin before taking the exit portal.
- After the exit: verify the completion stamp and coin mark in the Stamp Book. If only the stamp appears, return while the map remains open and search for the coin.
- At region milestones: compare your total against 5, 10, and 20 completed dungeons for the Slayer sequence. A stalled counter means you should inspect the Stamp Book rather than repeat a completed dungeon.
For Running on Fumes, stay up late when the option is available, then complete a dungeon that has never been cleared on that save. Replaying an old dungeon does not satisfy the condition. If the achievement does not unlock after the exit, the two most useful checks are whether the tired state was active on entry and whether the Stamp Book already showed that dungeon as completed.
Make a manual save at night before using the tired state on that uncleared dungeon. Activated Waystones can return you to their position when you re-enter a dungeon, but if the expected resume choice is missing, confirm that the Waystone was activated on this save before spending another day.
Open Hinterwald West before calling the dungeon route complete
Toxic Archipelago is both the secret dungeon for Something Rotten and the missing piece that turns the public count into the real total of 26. Its entrance is story-gated, so finding a blocked route early is not evidence of a missed collectible.
- Complete Overgrown Cave and finish the Private Investigations conversation sequence with Alex and the other adventurers at the Tourist Area campfire.
- Advance to the following night. Thea’s anonymous note starts the next stage; then meet her at the boat rental in the morning.
- Continue Goo Pipe Mystery until bus line 11 opens Hinterwald West.
- Speak to Alex, take the bus, clear the enemies in the first clearing, and follow the path beyond the Keep Out sign.
- Enter Toxic Archipelago, clear it, collect its coin, and watch the exit scene.
If bus 11 is not available, do not search the ordinary Hinterwald map for another portal. Check that Private Investigations is complete, advance through the following night, and look for Thea’s morning meeting. If the dungeon is complete but Something Rotten remains locked, check that you reached the result after the final room and exit scene rather than leaving through an earlier save.
Stop before Wassermann’s Arena and audit the base 41
Wassermann’s Arena is the end gate for this route. Make an open-map manual save before going there; it protects relationship evenings, shops, coin cleanup, scenic spots, trash sales, and unfinished dungeon work. The walkthrough sequence moves from that dungeon and fight into the closing scenes, while early achievement guidance warns that dungeon access is no longer available after the final completion. The safe response is a pre-entry audit, not an attempt to reconstruct the cleanup afterward.
| Audit group | Required base achievements | Detector before the final gate |
|---|---|---|
| Dungeons | Still Shaking; Double Trouble; Beginner, Intermediate, and Renowned Slayer; Completionist; Something Rotten; Running on Fumes | Every available Stamp Book entry complete, including Toxic Archipelago; tired clear already recorded |
| Coins | Shiny!, Sparkly!, Shimmery!, Dazzling!, Collector | Coin mark beside every dungeon; Souvenir Shop checked if Beginner is the missing entry |
| Relationships | Buddies; Friendly Overtures; Heart to Heart; Generous Spirit; Social Butterfly; Socialite; Altruist; Furry Friend; Dance of Death; Unlocking Potential | Three Friends, one completed relationship, Alex’s notes filled, Hannah’s shop saved, dog acquainted, third conduit slot and Combo Counter visible |
| Equipment | Efficiency; Enchanting; Tough and Buff; Charmed; Virtuoso | One Charm reduced to one slot, three swords enchanted, one of each armor type upgraded, Charm stack filled with no gaps, seven different Attack Conduits actually used |
| Exploration | Animal Lover; Water you looking for?; Grove Trove; Just Chilling | Cow fed, waterfall chest opened, all locked Hinterwald chests opened after Thea’s unlock, three distinct Scenic Spots used |
| Time and totals | Environmentalist; Introvert; Night Owl; We Are Amused; Relaxpert; Slayer | 300 trash sold, three solo evenings, three late nights, 200 Amusement, 200 Relaxation, 100 monsters defeated |
| Story | Detective; Town Survivor; Hinterberg Hero | Main investigation and rampage milestones completed; the final hero result remains for the ending route |
Three verbs matter in this audit. Own means keep the item in inventory; equip means place it in the active loadout; use means trigger it during play. That distinction becomes even more important in New Game+.
Choose the New Game+ file that matches your cleanup
New Game+ unlocks after the first playthrough and its closing sequence. It carries inventory, player statistics, and most relationship perks. It then asks whether to keep relationship progress or reset everyone to Never Met. Enemies are harder, four additional Attack Conduits are available, and dungeon levels rise from the original range of 1–9 to 5–14.
Keep another manual save after the final cutscenes and before answering that relationship question. It lets you change the carryover choice without replaying the ending.
Keep Relationships is the shorter achievement-cleanup choice because it preserves access to established character rewards. Reset Relationships is useful only if you specifically want to rebuild those scenes or pursue reset-dependent content. That recommendation is a route inference from the documented carryover rules, not a claim that either choice is mandatory.
Expect dungeon stamps and the completed-dungeon count to reset in New Game+. Dungeon completions also do not award Renown there. If a build based on Renaud’s Renown charm stops growing as expected, switch to gear, Charms, and carried statistics instead of farming NG+ dungeon completions for Renown.
Clear the nine New Game+ requirements in a safe order
| New Game+ achievement | Exact requirement | Fast verification and recovery |
|---|---|---|
| Top Model | Take a selfie in an Outfit | Equip an Outfit, open the Photo Mode unlocked through Travis, and use its selfie function. A normal screenshot is not the stated requirement. |
| Fashionista | Own 5 Outfits | Count owned Outfits in the wardrobe; do not count armor visuals as separate owned Outfits. |
| Style Icon | Own 10 Outfits | Continue the same inventory count to ten. If the counter stalls, verify ownership rather than merely previewing an item in a shop. |
| Super Strength | Reach 300 Physical Attack | Open the statistics screen after changing gear and Charms. The detector is the displayed Physical Attack value, not one large damage number. |
| Dressed like a Pro | Equip all Pro Slayer armor parts | Place every required part in the active armor slots together. Owning the set without equipping it is insufficient. |
| Honorary Monster | Complete the Monster Club quest | Follow the quest to its completion state; finishing the club’s full task chain also makes the related monstrous Outfit available. |
| Utility Belt | Equip 15 Charms at once | Use unlocked Charm slots and one-slot reductions, then count equipped Charms. Empty capacity and inventory-only Charms do not count. |
| All That Glitters | Have 1,000,000 Hinterbucks | Check the current balance before buying cleanup items. This is a held-balance threshold, not cumulative earnings. |
| Conduit Collector | Use 12 different Attack Conduits | Equip and trigger each distinct conduit in combat. Four new conduits were added with New Game+, so ownership alone is not the completion signal. |
Run the inventory achievements before spending toward a different one: first verify 1,000,000 Hinterbucks, then buy missing Outfits or equipment. For conduits, keep a written 12-item use list and mark one only after its attack visibly fires. For the armor and Charm goals, reopen the loadout after equipping the last item; that catches cases where an item was purchased but never activated.
Only after the base audit is clean should you take the open-map save into Wassermann’s Arena, finish the closing sequence, and launch the New Game+ cleanup. The cleanup is complete when the nine rows above are finished and the wardrobe, statistics, active loadout, quest log, and current Hinterbucks balance confirm the final unlocks.
