Fast Answer
Achievement data is one of the best launch-window sources because it reveals systems players will need for completion. This page groups public achievements into story, weapons, sidearms, bosses, secrets, collection, economy, and challenge goals.
Quick Facts
Use Achievements as a Route Map
Achievements reveal what the designers expect completion players to care about. Public entries point to weapon unlocks, sidearm tricks, boss challenges, secret areas, Rubies, outfits, Trypo challenges, currency collection, map progress, and New Game Plus. That is more useful than a generic completion paragraph because each category can become a checklist section and later a dedicated page.
The table below keeps requirements short so it can act as a tracker. Some public entries may hide exact conditions or platform-specific naming differences, so the safest content approach is to describe the requirement type and update the details after in-game confirmation.
Challenge Categories
Boss challenge achievements are likely to be the hardest early searches. Public signals include defeating a boss with one Bone left, avoiding Plasma Vials, staying Sparked, defeating a boss quickly, knocking a boss into a pit, or completing difficult fights cleanly. These goals require different builds than a first clear. A no-vial attempt values defense and route familiarity, while a speed or quick-kill attempt values damage and phase control.
Sidearm achievements should be handled naturally during exploration. If you wait until the end, you may have to grind enemy groups or puzzle setups. The checklist tool lets players mark which sidearm tasks are done as they test new tools.
Completion Page Expansion
After more playthrough data is available, this page can split difficult categories into focused guides: all outfits, all Rubies, Trypo challenges, secret areas, New Game Plus, boss challenge achievements, and sidearm tricks. Those categories are practical enough to deserve their own step-by-step notes.
For now, the main achievement page keeps everything connected so players can understand the full completion path before deciding which category to clean up first.

How This Guide Is Updated
This guide uses official Yacht Club Games pages, Steam listings, and publisher updates for stable facts such as release timing, developer, platforms, language support, Trinkets, sidearms, bosses, secrets, New Game Plus, and gameplay modifiers. Details such as exact room locations, hidden paths, boss order, and route efficiency are kept conservative until they can be checked through playthrough evidence.
When a detail is useful but not final, it is described as an area lead or verification note. That keeps the guide practical for early players without pretending that every secret room or boss route has already been solved.

Read categories if you want to plan completion, but avoid exact hidden requirements if you are sensitive to spoilers.
No. It is an independent fan guide that links to official and cited third-party sources so players can verify the information they use.
No. Use official store pages only. The guide warns against unofficial APK mirrors because primary sources do not confirm an official Android build.
Some item and area details still need room-level confirmation. The guide marks those entries as route leads until full playthrough verification is available.
