About this game
Description
Supplied by the Steam store
Gather a shaggy pirate crew for an underwater quest for immeasurable fortune!
What'Sub is a Co-op Extraction "Looter" where you and your crew of semi-professional submarine pirates brave the deepest, darkest corners of the ocean in search of adventure and riches!
Features
Online co-op for 1–4 (or more!) players
3 unique ocean biomes with procedurally generated levels
3 fully upgradeable submarines for solo and co-op play
Challenging risk vs reward gameplay
100+ unique character customization options
Descend into The Well
Navigate oceanic life, shipwrecks, and caverns to reach the bottom of The Well, a gaping sinkhole that recently carved itself into the ocean. It is still unknown how deep it really stretches, what rare treasures have been exposed, and what hidden dangers lie in wait...
Plunder the ocean
Fill your hold with the endless bounty of the deep sea. But beware—those blinded by greed may be swallowed by the deep. Your submarine can only go so far, and you will need to determine whether the risk is worth the potential reward.
Upgrade your submarine
Use your hard-earned riches to improve your submarine, making it faster, sturdier, and better able to withstand the increasingly threatening forces of nature.
Be the fanciest pirate YOU can be
Dress to impress! Don't let anyone tell you you're not the snazziest pirate in all the abyss. Grab a cup of coffee with the inhabitants of the Subyard or play a shanty with your friends, but try not to be too dramatic when your main audience tries to steal your gold.

Read full update on Steam ↗Bugfixes, Balancing, Oh My!
Hey everyone! Here again with a small but significant update!We've been working mostly on various fixes, but also on rebalancing the entire game. We're very curious to hear what you think of the new pacing, so please, let us know on discord or via the in-game feedback button! We highly recommend you start over to experience it properly (as some of you may have already bought everything). Savegames are located in AppData/Local/Sub/Saved/SaveGames - we recommend deleting *at least* the "Dock_" files as well as "PlayerWalletSave", but we won't force you to :)This will be the last content update for a while as we focus on getting all our ducks in a row and work up to a 1.0 release. We'll still put out bug fixes for game-breaking issues, but this will be the last content patch for now. Because of this, it's extra important that you let us know if there's something you would like to see dif...

A few too many bugs sneaked with the last update, so here's a hotfix addressing the most game-breaking and annoying issues. Let us know if you run into any other issues!Fixed an issue...... where currency would not update on the UI when selling/buying things... where enemies could see through walls... where the big submarine spawned with holes... that prevented big and small submarines from taking damage... where coffee mug interactions would stick to the UI... that caused the wrench to show up twice when exiting a station... where the "continue dialogue" button ejected you from stations... where the revive icon would show up on yourself after exiting a station Also made it less likely that large foliage spawns in the exit tunnelDisabled unfinished menusAdded an "abandon mission" button to the menuAdded a "retake tutorial" button to the menuReplaced palm trees and coconuts with new mo...
Read full update on Steam ↗First Update in a While!
Hey everyone! It's been a while since our last game update. We ended up delaying it twice to add extra stability and fixes, and now it's gotten much bigger than we intended!We're still working hard on the next major update, but for now we're soft-launching the new biome, the caves.So without further ado, the patch notes:Big additionsAdded the cave level. It's not entirely done yet - we haven't implemented any obstacles or enemies. But you're able to sail around, gather treasure and explore. Please let us know what you think!Because of this, it is no longer random which biome you load into when you dive deeper.Added clams to the shallows. Steal their pearls for profit :>Reworked how the periscope worksThe periscope used to be able to see everything in the level. Now it is both dependent on where your cursor is, and it has a max range. This was done to encourage exploration, since we fe...

Read full update on Steam ↗It's time for the big submarine update!
It's time for the big submarine update!We've designed this thing for 4 people, but theoretically there's a much higher limit on lobby sizes, so.. go wild! This update also features bug fixes for most of the commonly encountered issues. We have, however, encountered a new issue where the client sometimes doesn't load the submarine on level transition, causing them to fall into infinite void. We'll look into this on Monday (after a much needed weekend), but for now you need to rejoin the session to fix it. Sorry orz Added the big submarine! This one should work better for larger group sizes, but also takes more coordination to maneuver.We're still iterating on the design details of the big submarine so its layout may change slightly in the future.The big and medium sub have their own save games, so feel free to swap between them for different group sizes!Added visualization for submarin...

Time for the first big update! We hope you're enjoying the game so far (and if you didn't, maybe this update will help!). Remember to let us know what you think on discord, or by using the in-game feedback button :D Additions: Added pufferfish to the shallows Awoke the sleeping eel in the Kelp Forest Added new mechanic - Oxygen! If you run out you'll go unconscious, so be careful. Re-enabled pressure and added depth to the UI Added engine and propeller upgrades (we'll tweak the numbers over the next couple of days) Added custom app icon 🦀 Added an effect for drinking coffee. It's mostly cosmetic right now. Added a level at the bottom (see if you can reach it!) Added quests to the pause screen Fixes: Zip has zapped her last zee (changed voice for Zip) You can no longer queue infinite voice lines with the seashell phone Fixed an issue where you could go into debt when buying submarine...
