I went into this game with mixed expectations. On the one hand I utterly adore underwater games and their setting, on the other I hate hunting in every way, shape or form.
What I figured would happen is that there would be the fun underwater exploration and swimming around competing with the actively hurting fish aspect and that depending on which part was more prominent I'd give it a positive or a negative review...
Turns out it went a different way.
There are three locales in the game, which you'll go through in order. Each has a variety of missions... which you'll go through in order. They range from catching specific fish, to catching as many fish as you can in a specific amount of time (no minimum amount for success) to finding treasures or taking pictures.
To summarize, these are... lacklustre. At no point did I feel challenged, engaged or even relaxed by these missions.
The hunting aspect of the game is present, but forgiveable as there is no blood, no real skill involved and as long as you're super close to the fish not even any animations... I'm not sure that's a good thing in general, but for me it was.
Progression through the missions as well as capturing / photographing fish and finding coins and treasures give you money and EXP. Money is used for upgrades which make you swim a bit faster, require you to go up for a air less and to make the fishing and photographing slightly easier.
I will always
approve of an upgrade system, and I'm glad it's there... but I wish it would do a bit more. It's easy to get everything and the levels you gain do little more than unlock a few of the upgrades and then just give you bonus coins, and if I were to play a level on somebody else's profile and then be asked if he or she had all of the upgrades or none of them I wouldn't be able to tell.
Lacklustre is the name of the game here, and I can't say I recommend it.
It's better to just wait until World of Diving
makes it out of early access.
I did not factor this into the review, but I felt it was relevant to point out that there has been some criticism towards the developer regarding some of their business decisions.
Depth Hunter 1 was part of several game bundles and had promised Steam keys once the game made it here, instead it hasn't and we get Depth Hunter 2 instead which is supposedly practically identical.
Seemingly critical updates (like adding a radar for finding treasure that is strewn about) and more than the original 3 levels are locked away in DLC (review of that here
I'm not saying you shouldn't buy the game because any of that, but be mindful of it.
