Weapon Collector

Weapon Collector
Collected all the blueprints.



Important
Gun variants such as a "Shock Grenade Launcher" or a "Fire Sniper Rifle" DO NOT count towards learning a recipe. You will need to pick up a PLAIN RECIPE 3 times to unlock it.

The grenade launcher and the ice gun will probably be the most difficult to find. The ice gun can only be found AFTER you unlock the Glacier Passage. After unlocking the Glacial Passage, I found the gun several times in the ice area as well as the Blue Hole Shallows. The grenade launcher is most likely to spawn in the Blue Hole Depths.

Go through the doors to the Glacial Passage in the Sea People Village, once you are there swim down to the level with the giant mirror. Swim left and go through the passage. You will have to redo this puzzle in order to reach the mural.

To unlock the GYAO's you need to finish side mission "Stormy Night." Whirlpools will spawn on stormy nights and upon entering these whirlpools, you will be met with a boss monster. When you defeat the Mantis Shrimp the GYAO's should unlock. GYAO's are very similar to Tamagotchi's.... they pretty much are a Tamagotchi. You need to raise the GYAO to adulthood, let it die, and do it over again 5 times for this achievement.

Photographer

Photographer
Took 10 photos at Photo Spots.



I was able to complete this achievement by just questing and exploring. There are many photograph opportunities, the first one being in the Deep Blue Depths. Once you take your first photo, more begin to occur throughout the map. As you progress in the story, more photo spots open in different areas/times of day.

Eventually you will get a quest from Udo the photographer to begin capturing Fishmon. He will give you a new Fishmon to catch every Saturday, you have until Sunday night to catch the fish or you will have to wait until the next Saturday to try again.

Pro tip: Udo tells you how deep the fish are and WHAT YOU NEED to capture them....

Complete this by doing all of the VIP missions. Eventually, a news reporter will come into the shop with new challengers every week. You will go head to head in a cook off, having to play a Cooking Mama style mini-game. The final mission will unlock a new branch restaurant.

˗ˏˋ✩ˎˊ˗ SECRET ˗ˏˋ✩ˎˊ˗ Ration Eater

Ration Eater
Ate rations.



This one is potentially missable if you don't choose to pick up the rations in the Sea Blue base. I do not know if you are able to go back into the base so please just be aware. The rations will be found on the third floor of the Sea Blue base. You have to walk over them in order to complete the mission.

˗ˏˋ✩ˎˊ˗ SECRET ˗ˏˋ✩ˎˊ˗ Dev Killer

Dev Killer
Wiped-out all the developers.



This unlocks once you finish the game. During the credits, you need to find and "kill" all of the developer names before the credits finish. If you fail the first time, it unlocks as a mini-game on your phone the next day. It seems that the map "wraps" around, so, you can endlessly swim in one direction.

Credit to Wuss: It seems there is a common complaint you can't get this achievement on the first try. So, when it becomes an app on your phone we recommend trying for it then.

˗ˏˋ✩ˎˊ˗ SECRET ˗ˏˋ✩ˎˊ˗ God of Lightning

God of Lightning
Caught a fish with Mjolnir.



The Mjolnir has a percent chance to spawn in the Glacial Passage only. It can spawn in many different places on the map so be on the lookout for it. It will spawn in a big chunk of ice, you will have to break it out. You must kill at least one fish with it, doesn't matter the size of the fish.

Edit: Some people claim it took them multiple fish to get this achievement. Keep killing fish with the Mjolnir until it procs.

Edit (2): According to some comments it seems that the Mjolnir may only spawn on days with rain.

˗ˏˋ✩ˎˊ˗ SECRET ˗ˏˋ✩ˎˊ˗ Creature Hunter

Creature Hunter
Caught all bosses.



Says "caught" but it really means kill. Complete the main questline as well as the Stormy Nights questline to unlock this achievement. Check your Marinca app to keep track of all of the bosses you have already completed.

[Feeline]

Hey, I just got Thor's hammer on a sunny day, found it in the 3rd cave. So maybe there's a higher chance of it spawning on a rainy day, but it can still be found on sunny ones.
Thank you for your wonderful guide btw !

[Sharkster_00]

Yes Ration eater is the only achievement that is missable

[🄿ɸ🅃🅂🄲🄷🄸]

so just Ration Eater is missable?

[DerexXD]

You can actually get "A Dark and Cold Place" really easily, just dive down until Dave gives the warning that it's too cold and it'll count as having visited it

[palex00]

I can confirm that Mjolnir also spawns on sunny days: https://imgur.com/qw7wq6v

[Dunge]

The part about Mjolnir you say Glacial Passage. This is wrong, it is in the Glacial Area. It's also untrue that it need to be raining, I just got it on a clear day.

[Zleep]

Hi would you mind adding me? I want to talk about this guide

[DJ AnimeGirlFarts69]

I found mijolnir at bottom right of glacial area, it was sunny outside. I had to kill like 4 fish before i got the achievement
