Retail-first player guide

Lou's Lagoon Achievements & 100% Checklist

A spoiler-light checklist built from the confirmed 35-achievement retail list, with collection goals grouped by system.

How many achievements are there?

Steam and Xbox data list 35 achievements. PlayStation adds a platinum trophy on top of the equivalent goal set. The achievement list is especially useful for guide planning because it reveals what the game considers a full completion run.

Major completion categories

• Exploration: all radio towers, all treasure chests, buried items, crash-site discovery and ring challenges.
• Gathering: every resource at least once and every fish-scale type at least once.
• Progression: maximum Swirler, maximum all gadgets and all Builder blueprints.
• Social/story: talk to everyone, story discoveries and character-specific outcomes.
• Building/customization: build structures and gather clothing items.

High-value targets to track early

It’s All Connected — repair all radio towers. X Never Marks the Spot — find all treasure chests. Tipping the Scales — catch every fish-scale type. Gotta Swirl Them All — gather every resource. Daring Ace — master all ring challenges. Chame-lou-on — gather all clothing items.

Several achievements are story-spoiler heavy, so this guide keeps their detailed steps collapsed until the surrounding route is retail-verified.
