I really love the concept behind this game. The crisis management aspects makes for lots of funny and intense moments when you're all scrambling around panicking, yelling at your crewmates, while the submarine is being attacked and sinking to the ocean floor. That fun only lasted for so long before the underlying problems with the game became too apparent to ignore and I cant help but thinking about how much missed potential there is in this game.

There is a complete lack of an actual ecosystem in this world. The enemy variety in this game is pretty poor. Every single creature is obsessed with eating your boat and nothing else for some reason. Many of the creatures you encounter at the beginning of the game are the same ones you see at the end of the game. Every creature is functionally the same and doesn't change anything about how you would deal with them. The amount of health some enemies have is just way too high for no reason. The world is extremely boring. Areas on the map fail to distinguish themselves in any meaningful way. Theres no new major obstacles or challenges in each area. Instead, they just make the distance longer to travel to each outpost longer, making for even more downtime.

While the boat is moving to the next location, theres not really anything for crewmates to do besides sit around and wait for something to happen. When things do go wrong and disaster happens, that's when the game shines. Much of the fun in the game also comes from doing your missions. When the player has to leave the relative safety of their submarine to explore a ship wreck, or into a cave to destroy a creature nest, or explore an alien ruin, destroy an enemy vessel, etc. After you've done a mission a few times, you've pretty much seen everything and they become somewhat uninteresting though. Each mission becomes longer and longer as outposts get further apart, that it's just not worth the time or effort for trying to do some of the missions too.

The game has a few rivaling factions that you can choose to side with, which would be cool if they had more world building and major events or bigger impacts on how the gameplay played out. The only major purpose in increasing your reputation with a faction currently is so that you can unlock further biomes, everything else is too minor and irrelevant.
In smaller crews, players are pretty much forced to hire npcs to join their crew, otherwise its basically impossible to manage some of the tier 2 and 3 submarines. This wouldn't be a big problem if the npcs weren't completely braindead. And the best part is, if the npc dies, which it does extremely frequently, it doesn't respawn! So the crew is either forced to restart the mission or spend a lot of money on hiring new npcs, which most of the time just isn't feasible.

There's just a big lack of progression overall in this game. The upgrades for your submarines currently are underwhelming to me. It would be cool if you could add things to your submarine throughout the campaign. Not talking about buying a new one or making your own, that is different.
Leveling up your skills and unlocking talent points also feels underwhelming and could be better.

Oh, and jank. Lots of jank. Weapons not firing, Get bit through the walls of your submarine, Screen randomly pans off-screen every few minutes, Mobs randomly regenerate their health, Have your game crash in the middle of a mission for no reason, And lots of ragdoll physics and movement issues.

The game has a lot of potential to be so much better than it is currently. I really like the concept behind this game. I still had a lot of fun with the game, which is why im rating it somewhat high and still recommending the game. I think its worth playing but also still has a lot of work to do for improvement in it's current state. I dont know who thought it was a good idea to take this game out of early access and increase the price even more.
7/10. For the price, especially for a co-op game, 6/10

Negative review only because this game took my friends from me and now they wont do anything else.

Great game, awesome mods, the community is nice but don't take it for granted; Public Servers can be hellish.

When with randoms its about a 33/33/33 Toss up of Competent crew, Griefers/Clowns/Trollers, and VERY unpleasant people (Typically the host) but when you find that server of all around exceptional people its great.
