Step 1: Open the Interactive 100% Tracker
Start by recording what you already completed. This prevents repeated backtracking and makes it easier to identify whether the missing progress comes from a boss, Trinket, achievement, quest, upgrade, or collectible.

Why use the tracker first?
- Your progress is stored locally in the browser.
- You can return after completing another region.
- Completed and remaining categories are easier to compare.
- You avoid checking the same location repeatedly.
Step 2: Complete the Trinket Collection
Trinkets are one of the largest cleanup categories. Mina has 60 numbered Compendium slots, 61 usable forms including Plasma Jug. These cover normal pickups, NPC rewards, shops, quest rewards, upgraded forms, and recovery routes.
Use these Trinket guides
- All Trinket Locations — compare your collection against the full list.
- Missable and Easy-to-Miss Trinkets — review rewards and routes commonly overlooked.
- Black Market Trinkets — check whether a missed item can be recovered.
- Trinket Database — inspect individual effects, locations, and usage notes.
Recommended Trinket cleanup order
- Compare your inventory with the full list.
- Mark every item you already own in the tracker.
- Review quest and NPC rewards.
- Revisit areas opened by later movement tools.
- Check recovery options only after checking normal acquisition routes.
Step 3: Defeat Optional and Secret Bosses
Finishing the story does not mean every boss has been defeated. Several encounters are hidden behind side quests, shops, dialogue choices, special doors, optional routes, and late-game activities.
- Check the prologue Nether Kraken encounter.
- Review all regional and Spark Generator bosses.
- Complete side-quest boss encounters.
- Check secret bosses unlocked through NPC and shop interactions.
- Confirm all post-fight rewards were collected.
Use the Mina the Hollower Secret Bosses Guide for locations, unlock conditions, and rewards.
For the broader order, see the Boss Database .
Step 4: Complete Weapons and Sidearms
Completion tracking should include both Mina's main weapons and the Sidearms collected throughout Tenebrous Isle. Check acquisition, upgrades, dual-Sidearm access, and any achievement tied to a specific weapon or Sidearm.
Equipment checklist
- All five main weapons unlocked
- Weapon upgrades completed
- All available Sidearms collected
- Dual-Sidearm access checked
- Sidearm-specific achievements reviewed
- Trinket and weapon combinations tested where required
Read the Best Weapons Guide for loadout recommendations.
Step 5: Finish Side Quests and Minigames
Side quests can unlock Trinkets, bosses, equipment, minigames, NPC progression, and achievement conditions. A completed story route may still leave several quest chains unfinished.
- Revisit NPCs after major regional milestones.
- Check whether quest rewards were collected.
- Complete fishing and other recurring activities.
- Review racing, Ring Dive, Wrecker, and similar challenges.
- Finish quest chains that unlock optional bosses.
Step 6: Review All 50 Achievements
Mina the Hollower has 50 achievements or Feats covering story progression, challenge runs, Sidearm tasks, Trinket objectives, collection goals, and minigames.
Some achievements unlock naturally during the main story, while others require specific equipment, unusual combat setups, strict challenge conditions, or activities that are easy to miss during a normal playthrough.
Use the Achievement Difficulty and Cleanup Guide before attempting challenge-based achievements or starting another playthrough.
Achievement categories
- 8 story achievements: tied to major progression milestones and story encounters.
- 12 challenge achievements: special runs and restricted objectives that may require careful planning.
- 15 Sidearm achievements: combat tasks requiring specific Sidearms, enemy setups, timing, or special interactions.
- 7 Trinket achievements: objectives connected to Trinket effects, equipment combinations, and hidden mechanics.
- 5 collection achievements: rewards for completing major collectible or equipment categories.
- 3 minigame achievements: objectives connected to optional activities and side challenges.
Achievement cleanup checklist
- ✓ Complete all story achievements
- ✓ Review challenge-run restrictions before starting
- ✓ Complete all Sidearm-specific achievements
- ✓ Complete all Trinket-specific achievements
- ✓ Finish collection achievements
- ✓ Complete all minigame achievements
- ✓ Check setup-based achievements separately
- ✓ Record achievements that require another playthrough
Important challenge-run warning
Achievements such as Below Zero may have strict rules involving upgrades, pickups, equipment, or other actions. Confirm the exact restrictions before beginning the run, because some mistakes may require restarting the attempt.
Setup-based achievements such as Bounding Bonanza should also be tracked separately instead of assuming they will unlock naturally during story progression.
Step 7: Check Upgrades and Collectibles
A final equipment sweep should include permanent upgrades, capacity increases, regional collectibles, and travel infrastructure.
- Health upgrades
- Plasma Vial capacity
- Spark Containers
- Joule capacity upgrades
- Trinket Bags and equipment slots
- Bonestones and other regional collectibles
- Mirrors, train stations, Underlabs, and shortcuts
- Fish trophies and fishing rewards
- Songscrolls or equivalent music collectibles
Step 8: Review Endings and Missable Content
Before ending the run, review content that may depend on early-game decisions, dialogue, quest timing, or the prologue.
- Optional prologue encounters
- Normal ending requirements
- Hidden ending requirements
- Dialogue-triggered encounters
- Quest rewards that may require another NPC visit
- Challenge conditions that cannot be repaired mid-run
Read the Hidden Secrets Guide before considering the save complete.
Step 9: Prepare Before Starting New Game+
Do not enter New Game+ until you have checked every item or objective that may be easier to finish on the current save.
- Mark completed categories in the interactive tracker.
- Spend or bank resources that do not carry over normally.
- Confirm missed prologue or challenge content.
- Record remaining achievements requiring another run.
- Review your preferred weapon and equipment setup.
Final recommendation
Keep the current save available until you have confirmed that the remaining goals genuinely require another playthrough.

Yes. A safer weapon can make backtracking and cleanup less frustrating, especially when revisiting older areas with awkward enemies or hazards.
