A few ideas

Canadian_Chicken · January 2017

Hello everyone, I have compiled a list of ideas ranging from small to medium, nothing toobig. These ideas could add a little more realism to the game and in my opinion (Even though I'm not a developer), they aren't too hard to add.

1. A player pressure device...

I don't know if the developers wanted Subnautica to have some sort of Sci-fi gravity so that the player could go as deep as they wanted and not get crushed to bits, but seeing as the vehicles are affected by pressure, I don't see why the player isn't... If a hunk of metal is crushable at a certain depth, then a human would crush easier. So my idea would be to add a device and mechanism which doesn't allow the player to go too deep without this certain device. You would be able to put it somewhere in the player's inventory section in the PDA. You would also be able to upgrade the depth you can go to with the modification station.

2. Camera upgrades for the scanner room...

Cameras in the scanner room are pretty cool to use to scout out areas or look at stuff without sending yourself out into the wild, but let's face it. It's pretty useless. I think there should be some upgrades for the cameras that you can make in the fabrication station in the scanner room. Here are some ideas for upgrades:

- Regeneration when swimming around

- Hand to grab materials and a small storage place (maybe like 4 inventory spaces)

- Swim speed

- Sonar

3. Teleportation torpedo

Hold on, it may sound really OP, but it's not as good as you think. I think for the Seamoth and PRAWN suit torpedo system, there should be a teleportation torpedo. This torpedo would teleport any creature it hits maybe around 10 - 20 meters away, which would allow the player to escape. It's just another version of the vortex torpedo but instead of flinging it away when the vortex stops, it just simply teleports it away. (This would use the same effects as a Warper teleporting)

4. Food compressor

Now I did get this idea from another post from someone on this forum, but my idea is a bit different. I think there should be a machine to compress certain things into nutrient blocks, which the player can then eat. The thing is I think the things that can be compressed should be plants, not fauna.

5. Moonpool repairing

This is pretty self-explanatory, but just in case you don't get it, I think the Moonpool should be able to repair the vehicles you put in it. (PRAWN suit and Seamoth for now)

6. Wear/Dirty system

I think after time, your PRAWN suit, Seamoth or Cyclops should get dirty, chip paint, etc... (but without damaging the vehicle) and the only way to fix it is to add paint (which should be a thing found in wrecks) to make it look good again. To add the paint you would need to access the Moonpool while your vehicle is docked (Or just in the water for your cyclops) and then right click with the paint in hand to use it. (This isn't my strongest idea, but I think it was worth sharing)

Thanks for reading! Please comment on what you think for each of these and if you would want them in your game!

Humans don't crush because they aren't hollow. Now, the problems arise from the effect the pressure has on their blood, specifically with Nitrogen, and also too much Oxygen. If you got rid of those two problems, however, humans would be able to go quite deep indeed (although I'm unsure of exactly how deep before tissue damage, or damage from the pressure required to force air into their lungs, or inability to move would set in due to the pressure).

Humans would start turning into toothpaste tubes at some point. We may not be hollow but we still have an internal pressure and lacking the ability to equalize the internal and external pressure means we'd react the same way a can of food would under a hydraulic press.

But as you pointed out, well before that, we'd reach depth where our lungs would be unable to expand well enough to pull in air.

Ignoring gravitational differences - since underwater the pressure is essentially the weight of the air and water above you and that is defined by how hard gravity is pulling down and exactly what the density of the water is - few professional free divers will attempt to go past the 400ft point. Yes world record for freediving is ~700 ft, but that was essentially diving straight down with the benefit of a weight pulling them and then straight back up. It wasn't a case of going down and doing some sightseeing before returning.

Divers with SUBA gear have maxed out around 1,000ft.

That being said, either the future is built out of shoddy crap or the planet we are on has a much greater gravity than Earth. Modern Era subs have a crush depth of over 2,000ft, so the idea that our Cyclops needs special reinforcements to even make past 500ft suggests that we should probably not ignore gravity as a factor in this equation. If that were the case, then I'd expect us to have a far more shallow safe diving range.

Dear Unknown Worlds Entertainment Team and Subnautica Developing Team,

I have got an Idea.

You might not see this post because you guys are very busy making this incredible game.

I know it's hard to make a game, especially one like Subnautica.

My idea might be or might not be included because YOU decide.

What if, the character you play as is actually the commander of the Aurora. When you visit the Aurora you would have flashes of how it looked when it wasn't burnt down.

For example you would walk into the crew quarters and see a bunch of people in their rooms talking and you would say to a random guy "Hi Jimmy" (or any other name or something like that).

And then you could be piloting the ship (with other people because a big ship like the Aurora can't be piloted by 1 man) and suddenly a crew member in the "cockpit" is like : "Engaging the slingshot maneuver" (or something else you get me)
and then there's the flash of green and explosion sounds everywhere. The alarm sets off and you make a run for the escape pods.

Since your the commander, it would make sense that you have a priority to take an escape pod.

If this idea is taken, I suggest that the idea is either at the beginning of the game as part of the intro sequence (because if I remember the 1st game intro, it was a lady voice talking about the Earth conquering the galaxy and that the Aurora was one of these Alterra Ships and it was struck by a "Mysterious Powerful Energy Source")

It would make sense since the "woman voice" intro is gone to reflect that "Mysterious Powerful Energy Source" in the intro of the game.

OR

You could include the idea as flashes as you visit the burnt down Aurora. You would walk into a room and you would be thrown into cinematic mode when the Aurora wasn't burnt down and you had your friends and your crew members working at their stations etc.

This is a long post to enunciate a "little idea" even though it would take months to realize in a game like Subnautica.

By the way, this is JUST an idea. As I said before YOU decide what you implement in the game. And I know that you guys have lots of surprises up your sleeves !

Anyways, Keep up the AWESOME work !

Thanks for reading if you read to here.

Bye !

Subnautica depths are measured in meters, not feet.

100m = 328 ft | 200m = 656 ft | 300m = 984 ft | 500m = 1,640 ft | 900m = 2,952 ft | 1,050m = 3,444 ft | 1,300m = 4,265 ft | 1,500m = 4,921 ft | 1,700m = 5,577 ft

I allow myself to quote a forum user namend @scubamatt right here, because he put alot of effort into a huge post to show why humans do not get crushed fast when they dive. Here is his post, enjoy and learn.

Lets start here shall we https://en.m.wikipedia.org/wiki/Atmospheric_diving_suit

In this link above the only way they got to these depths is with HIGHLY sophisticated and specialized equipment.. In fact his wet suit is more of a submersible then a suit..

And even this suit has its limits.. 500 meters let alone 1000 meters would be fatal to anyone outside of submersible without proper gear..

So you are correct in saying what you stated. That is only to a degree.. As I stated in suggestion about wetsuits.. At 1000 meters we would in fact be crushed by the sheer weight of the ocean.

I really enjoy when a non-scuba diver attempts to lecture me about real world diving. Particularly when they use the *wikipedia* as a resource, and then tell me I'm only correct "to a degree".

I gave you a very simple explanation of why people do not 'get crushed like a submarine' so you would understand the basic difference between a hollow, air filled pressure hull and a human who is mostly solid and relatively incompressible. I wanted to avoid dumping a lot of math and science on you, but I'd be glad to cite you a number of *real* articles about deep diving if you'd like. That would be tedious though, and you'd probably not enjoy reading them very much.

Let's take your statements in order, shall we?

1. You linked an article to a submersible, not a wet suit. It clearly states that in the first paragraph. It also states that the interior of the submersible is maintained at a pressure of one atmosphere. The article proves that submarines, because they have pressure hulls and maintain the interior at normal (surface) atmospheric pressure, have crush depths that are easily calculated and cannot be exceeded without serious, sudden consequences. Your wikipedia link completely supports *my* post, not yours.
2. You say "500 meters, let alone 1000 meters would be fatal to anyone outside of a submersible without proper gear." I'll assume that you mean gear beyond typical scuba diving equipment, which includes a regulator, pressurized breathing gasses in tanks, and a suitable face mask. Either way, your statement is completely wrong. In fact, the world record for a manned chamber dive is over 700 meters, and was set in 1992. The divers stayed at that pressure for about two hours, doing pipeline exercises.
3. The actual point at which human bones are crushed by water pressure is called the "snow line" because at that point most bones (which are filled with air and marrow) are crushed to splinters and then those splinters fall to the ocean floor. The snow line exists at about 22 miles deep. So, no, your body will NOT be crushed at 1000 meters depth. They have in fact recovered bodies from greater depths than that, far too many times. When things go wrong diving, the corpses of the divers do not typically return to the surface without help.
4. There *are* serious dangers involved in very deep diving, but they have nothing to do with your body being crushed like a submarine. The real dangers have to do with HPNS (High Pressure Nervous Syndrome), dysbaric osteonecrosis (bubbles forming in your bone marrow), oxygen toxicity (this is why nobody breathes 'air' at great depth, they breath specialized mixtures), and most importantly tissue saturation that makes decompression take days rather than minutes or hours. The algorithms used to calculate decompression times for diving at depth are untested beyond a certain limit, and nobody is willing to risk their lives testing the numbers when we *do* have submersibles available.

This game captures the 'feel' of diving very well, but it doesn't present a realistic simulation of diving. They do increase your air consumption as you go deeper (realistic) but they do not force you to make decompression stops before surfacing (unrealistic). They allow you to carry more tanks so you can stay submerged longer (realistic) but they refill automatically and with common air (unrealistic, dangerously so below 30m or so). I can go on at great lengths listing where the game designers had to choose between realism and fun, but by now you should have gotten the point.

If you have access to a swimming pool, you can see for yourself the difference between submarines and scuba divers:

Get two balloons and a can of compressed air (the kind you use to blow the dust off your keyboard). Use the can to inflate the first balloon to the size of your head, then tie off the balloon. Use a marker and draw a couple of lines on the balloon as a visual reference. Take that balloon and get in the pool, go over to the deep end, and then holding the balloon, swim down to the bottom of the pool. You will see a visible difference in the size of the balloon as it compresses under the pressure of the water around it. It will get smaller. This is because the air pressure inside the balloon is still at surface atmospheric pressure, while the water pressure is continuing to increase as you go deeper. This is what happens to a submarine, if the hull of the submarine is not stronger than the water pressure pressing on it. If you kept going deeper, the balloon would keep getting smaller and smaller until it looks almost empty in your hand. We do this in diving classes to teach divers how things work, actually.

Now get the second balloon, and blow it up to the same size, but tape the nozzle of the compressed air can into the neck of the balloon. This is so you can add compressed air to it later. Take balloon/can combo over to the deep end of the pool, and this time, when you get to the bottom and see that the balloon has shrunk in size, give it a little shot or two of compressed air. The balloon will return to its original inflated size, but the air inside is now under pressure. In fact, the air pressure inside the balloon exactly equals the water pressure outside the balloon, which is why scuba divers do NOT get crushed like submarines. The deeper we go, the more pressurized our air supply becomes to match the surrounding water pressure. This also means the deeper we go, the more air we consume with each breath, and the quicker our tanks will be expended. I can stay underwater over an hour on one tank, in very shallow water. In deeper water that same tank may only give me ten minutes of time on the bottom before I have to start back up.

Still underwater with your pressurized scuba diver balloon?

Good, now remove the balloon from the can of air and tie it off. Its the same size you had on the surface, but its under pressure. Take the balloon back to the surface, and watch it as you ascend - it will expand, possibly to the point of popping. This is because as the water pressure decreases, the interior air pressure is greater and it pushes outward on the skin of the balloon. This is why the absolute first rule of scuba diving is "Never Hold Your Breath". As a diver ascends, the air in their body expands, which can cause their lungs to burst if they try to hold their breath. Tiny bubbles in the diver's blood stream *also* expand, which is what causes Decompression Sickness (aka 'the bends'). It is incredibly painful, and can kill you - imagine if your blood started to foam like a carbonated beverage that was shaken up - and it is why divers perform decompression stops at regular intervals of decreasing depth. They are allowing time for the tiny bubbles in their body fluids to expand and escape in a safe and slow manner. A deep diver who rockets to the surface in a panic will almost certainly suffer a rapid and agonizing death, unless he is immediately placed back under pressure (in a hyperbaric chamber, for example). They do not simulate decompression effects in game, and for this I am grateful. It is a level of realism that we really don't need.

I hope I've made it very clear why submersibles and scuba divers are not affected by water depth in the same way, and without burying you in technical data. If you'd like to learn to dive yourself, you can join PADI (Professional Association of Diving Instructors) at www.padi.com, or SSI (Scuba Schools International) at www.divessi.com , I'm a member of both though I prefer PADI's training over SSI's.
