This simple guide provides descriptions, goals and tasks required to unlock 80% of achievements currently available in the Resubmerged version 1.22.33.

Why only 80% you ask? I haven't managed to unlock the last 3 achievements despite my best effort, so they are currently either bugged or do not trigger properly. If you want me to update or add anything to the guide (tips, locations, corrections etc) feel free to leave a comment, cheers!

These achievements are unmissable if you play from start to finish as they are tied to progression of the main story:

Discover the Forgotten Fjords.
Complete the tutorial zone and reach the main area of the Fjord.

Discover the Sunken Coast.
Complete the main quest line in the Fjord and reach the second map.

Discover the Abyssal trench.
Complete the main quest line in the Coast and reach the third map.

?????
Complete the main quest line in the Abyss and defeat the final boss.

There is only one and it is missable I think if you won't finish the whole Morgen's Tear related quest line first in the Coast and then in the Abyss.

Defeat the Morgen’s Tear.
Complete the whole Morgen's Tear side quest, culminating in a final duel in the Abyss.

These achievements are obtained by upgrading your homebase and each of the 3 starting classes of subs to level 3, or by purchasing finished level 3 sub directly from the shipyard later on.

Fully upgrade a Royal ship.


Fully upgrade a Dweller ship


Fully upgrade a Icer ship


Fully upgrade every ship.
Have all the above level 3 ships available under your command.

Upgrade home base to max level.
Each map has 1 hidden home base. Upgrades carry over between maps, so you have to upgrade only once. 1st level costs 1000g, 2nd level 5000g and 3rd level 15000g.

Defeat 100 enemy ships.
Destroy 100 enemy subs. I found the biggest pirate activity was in the first map, on a triangle between the City of Ice, Tonnesburg and your home base.

Defeat 100 creatures.
Destroy 100 creatures of the Abyss. Greatest concentration is naturally in the Abyss and Endless Corridor, however some are present in the Coast as well.

These achievements didn't work in my playthrough for reasons unknown. Maybe you will have more luck!

...
I suspect this one is about finding every single landmark on every map and/or possibly selling the maps/charts to the cartographer guild in the Coast. At least 2 landmarks didn't register for me compared to the old version of Diluvion.

...
Obtain and have 1 million gold on you. This didn't trigger after reaching 1M for me, switching zones, docking and reloading/saving didn't help either. Haven't tried to finish the game with 1M in purse though (which is worth a try).

Collect every ship emblem
Ship emblems are collectibles/loot which can be found in specific locations. However I've managed to find only 2 out of 11 and I suspect most of the rest are missing compared to the old version of Diluvion. Here is the list so far:

• Crevasse Guardian. Found in the Endless Crevasse - Abyss map.
  
• Mystery 2 Emblem. Found in the Sewers - Coast map (from the main entrance to the sewers marked on the map head straight until the first dead and then turn right, keep going straight all the way destroying baddies and mines until you reach the second dead end. There should be a small container on the floor with this emblem).

Thanks for checking out this simple guide, hopefully it was of some use to you.
