I have just started playing the game and as I said before, so far so good. The only problem I am having so far is that the oxygen tank for the submarine is very small and you have to be careful and watch the oxygen level or your crew suffocates. You still get points and money for how far you did go, so that’s good. But it does make it challenging to play at first with the tiny oxygen tank and slightly expensive upgrades. But with a little grinding you can get enough cash to be the terror of the seas lol. I I’ll give you a tip for the best thing to get with your wad of cash after completing the first mission: get better oxygen tanks or you will be bobbing to the surface like a cork so your crew doesn’t suffocate. It is not like the traditional ww2 submarines that run on Diesel engines on the surface and electric underwater. You just run on electric engines, so the fuel is for the generator to recharge your batteries for the engine. These are a few tips and pointers for first time players. It is a good game, just watch the oxygen level.

I’ve “completed” the submarine before and enjoyed the immersion the game gave me at that point, but I stopped because I couldn’t get the 36 stars needed to unlock the other two modes. I think rather than unlock them with stars, you could buy them with the in game currency. It’s just an idea, and I think if it were to be a good idea, the price for each of the two modes should be around 10k (10,000). Another thing I’d want to see is a VS. mode between players. Not in real time, more or less a time attack to see who can get farther and who is more skilled. No ranks, just matching up with a even opponent with a different set of skills with handling the underwater abyss. Again, awesome game and I also noticed the 3D graphics in the sub, I’d think the mines in the game deserve some appreciation though :/

So so far the options are pretty good but sometimes I find the battery to small even with max and max generator so like can we get more parts like titanium is good but like can we get layered titanium that can sustain more than one mine and fuel is useless when you have a reactor so I would like to see a later upgrade in that for more uranium storage and maybe a radar that has 4x that maxes hazards more visible just saying when you get all the parts it’s like all has fallen into place and you just have to evade rocks oh and we need better oxygen storage because it seems a bit to small with the other ones oh yea to counter out these powerful upgrades add tanks that hold more water and air because these parts will add extra weight

The progression in this game has been well thought out. The further you progress, the less you have to worry about, but the more things to keep track of. This game is a hidden gem. The game lasted me about 3 days so far and I have already gotten all of the upgrades, and reached the end. And all that I have left to do is get all of the stars to unlock the other modes, which seems to be a really tedious process since the stars sometimes just seem to be scattered around instead of being in places you would expect them to be, like hard to reach places and caves. Other than that I would definitely recommend this game. Not every game lets you be the captain of a nuclear submarine. 9/10
