instead of the skill tree disabling going down other paths, instead have it use a points based system, where if you went down multiple paths you could get only a tiny bit of each. also let the escape pod instead be your bed, where you can ofcourse sleep. but also escape if you need edit: i like how the hydra is just the sea truck but better

[@loganfaith1921]

Yes i agree with this EDIT: because i was just going to comment the exact same thing.

[@PyroGam3s]

you should be allowed to unlock the entire skill tree, it would be a let down otherwise. There are other things you can do with it to limit it if you need to. Such as only allowing a certain number of branches to be active at the same time. Or only being able to spend a certain amount of points across the tree. Re-spending skill points to change the nature of the submarine would not only be exciting, but gives players more versatility in how they use the submarine for different situations. Re-spending could happen on the fly, or only when docked. So, even if we can't activate the entire tree all at once, we can still unlock everything and continue to customize, rather than be stuck in a certain configuration.

[@mishazerg]

​@@PyroGam3sI don't know if there will be any bases at all, but anyway i think it would be better to be able to re-spend points in some alien base in middle of the map, or something like this.

[@MrNomad-0912]

I actually really like the skill tree concept for the upgrades! It's a really great twist on the pre-established system and, like you said, it would add a lot of replayability to the mod. Either way you choose, best of luck to you in the development of this massive undertaking. (I do think it would be really cool if the hydra flooded, and just sunk forever until you couldn't see it anymore)

[@jessicaorr130]

flooding, then sinking and then if it hit terrain it left a wreck, or if it missed the terrain it would just get deleted at a certain depth? then if you get lucky you might be able to salvage from it. alternatively, it gets left as a floating wrack with a beacon on it, but only if it's not in the lair of the leviathan (assuming there is a section of map where it lives) then it's just gone so the player can't mark what area is unsafe using that wreck. alternatively alternatively, it becomes an anomaly after an arbitrary amount of time and you could then salvage it.

[@ishaanagarwal1705]

Man i just started playing subnautica again and you are working on making it even better. We apprentice your efforts . You have our love and support.

[@VeraVemaVena]

For the upgrades, I think both Subnautica's modules and the skill tree could work. The module slots would cover the basics like depth, engine efficiency, hull reinforcement and storage (assuming the Hydra has pre-built lockers like the Cyclops) while the skill trees allow you to specialise the Hydra how you see fit. This could also allow for you to upgrade the Hydra without going down a specific path. For example, you could have a more powerful and/or energy efficient Perimeter Defense System down the Tech route, but could also use the basic one by crafting it as a module.

[@nicholasobviouslyfakelastn9997]

I'd love to have a skill tree that could tie in with a dry dock or something. Exploring anomalies and such would unlock possibilities for the skill tree and would increase the amount of skills you could have. You can unlock every skill in the tree but installing them can only be done in the dry dock (or in some sort of home base type of thing) and you can uninstall skills to get the resources back. I'm a bit wary of having permanent skills where if you pick the wrong skills you're permanently locked out of some other skills you'd really like to have tried. A way to reset skills without resetting the game would be pretty essential.

[@TheMusicalman79]

Usually, I don't comment on videos but the whole skill tree idea for the Hydra really inspired me. The best thing any skill tree needs are capstones to the paths you can take. Once your near the end, you should feel like you are in a vessel that has survived through thick and thin. Here are my ideas. They will be pretty powerful, but you can only pick one and these upgrades would come right before the end. Every path has two capstones because every path you described has two real different major points. Tech capstone 1 - Alterran Engineering. You can equip a second unique compartment, but this second compartment only functions at 50% efficency (IE half size for the fish tank) Dont ask how it fits, it does because reasons (look, these are dumb ideas) Tech capstone 2- Precursor Knowledge. The Warp Drive now becomes highly efficient. Biological capstone 1- Livin Large. The Hydra now creates oxygen inside itself at zero cost. Biological capstone 2- Leviathan Paintjob. The Hydra can now be painted like one of the Leviathans living in the void, causing that specific breed of leviathans to leave you alone completely. The paint job can be changed whenever the Hydra is docked (to prevent players abusing the crap out of nondetection) Crystalline capstone 1- Strength of Crystal. The Hydra is now completely coated in crystal, giving it a huge health pool and more damage reduction. Crystalline capstone 2- Power of the Crystals. When using Crystals and crystals only to generate power, you now generate much more. Ultimately, these ideas are merely my way of suggesting that every path have something at the end that completely alters the Hydra in a major way. Something powerful but costly, locked behind the toughest of materials and what not.

[@Lord-xm7zn]

The submarine is great, even if it's only a concept! But I have a suggestion about the backroom section: the aquarium seems to be the least helpful, comparing to the other modifications. Instead I would recommend to redesign it for the living compartment by making it a "sim-painting", "sim-window", or something like that. You know, to make it more comfortable during a sleeping time, while the backroom will be occupied by more functional upgrades.

[@Aci_yt]

The aquarium will be more useful than an aquarium in the regular game, for reasons you won't know just yet :P Let's just say being able to transport certain creatures will be vastly more important than in the base game!

I would make the living quarters a more custom mesh affair so as to optimize the space allotted in the small area. A built in bed in the back of the area would allow for other decorations such as desks, chairs, monitors, planters and the like to be placed.

[@KikadaArty]

for me, the 3th option for the destruction is the most interesting not only would u get those panic last moments to make a run for the escape-pod before it all blows up, similar to how it happens with the cyclops (you could even get a tense music, like in the original game, to make those few moments very memorable) but the process of finding the permanently-added wreckage to the map, with ur stuff in it (so u can recover some of it, and not lose all of it forever) is like the coolest part it serves as not only a very cool and novel piece of modular story-telling that will be individual for each player, but it will forever be there as a reminder of ur mistakes, and to hopefully serve as a way to teach player to not make them again

[@davanmar7731]

It would probably be impossible but it would be so cool if the hydra started being crushed by the depths, getting smaller while flooding and when it breaks it collapses in on itself like a can or how submarines also break when they are too deep

[@kittencaboodle8124]

this is SO COOL and unbelievably creative! I can't believe this was all made by one person

[@dinkeycat]

From a balancing perspective, the skill tree should lock you out of other branches, forcing players to think more strategically about what they choose, I do like the idea of the three paths, and generally think this is a good idea that has the potential to be really well made. Edit: how the heck did everyone here come up with so many good Ideas on other ways this could work? You guys are seriously geniuses

[@dinkeycat]

On the other hand, from a creativity perspective, not locking branches when players choose upgrades could provide an impressive level of "buildcrafting" potential, and if balanced correctly (something like having a maximum amount of upgrades unlocked at a time) could really help the whole experience

[@tea_bag4258]

Or there could be all branches opened, but some upgrades would close others, like: If you start upgrading speed or some sort of that in tech branch, it would lock down stealth upgrades in bio branch, cause it is impossible to make engine more silent with such power

[@dinkeycat]

@@tea_bag4258 that's a good way to do it, but I would think that those options would be the starts of branches. If they were not, though, I would wholeheartedly agree with you

[@sythrus]

Or it could lock out other paths and you eventually unlock the other paths as a post-story upgrade

[@dinkeycat]

@@sythrus that could work.

[@imnotreal3213]

The hydra is an insanely brilliant idea! Plus the fact it can rotate on its axis is just a chefs kiss to show the passion in this mod! However I noticed that you can upgrade the depth module for the hydra and it gives me a feeling that Aci is planning for something to be near the bottom of the void as a final place you can go for the storyline just saying. Now something I would enjoy is allowing you to unlock the full skill tree, however it requires you to get more and more materials as you go before you can unlock it completely, it would also allow for you to be able to put parts of the skill tree behind the doors of those precursor locations, adding a difficulty curve as you go and even further encouraging you to try and go in.

[@plague_-_]

yes 100x yes for the skill tree, as long as it looks like the iconic pda style

[@abdallahbaloch]

This is amazing! I do have some ideas for the livings area though, you could make the bed smaller (like the seatruck fold up bed) to allow for more building space, maybe add shelves and allow for more decoration options. I hope the living area can be really cozy, like the only space in the depths of the void that’s friendly.

[@robowyatt398]

i really like the skill tree idea. it adds a level of progression that i feel the exploration lacks, due to the relatively small amount of stuff to explore (could be wrong, just going off of what we know currently) something like a skill tree would add to it and make exploring more thrilling and personal as well as it would just make you more attached to your hydra as it takes a lot of time and (i would assume) recourses to get far into the tree for the destruction part id go with the name of hydra and have it break into 4 parts, the driving part, the storage compartment, the living quarters, and the module slot could all be spread across different clusters if you were near one or floating in the void near where it broke so you could have a chance to retrieve your stuff that was in there while staying as a challenge in the void and being different from the cyclops

[@rishoh]

I really like the skill tree Idea, Having multiple upgrades that all affect the performance and abilities of the sub sounds really fun. But maybe instead of locking off the other trees when you chose one, you could make it so that certain options are exclusive instead. For example, let's say each path has an upgrade for the propulsion, the tech path reduces noise but boosts speed, the organic path increases energy efficiency and generates clean water while moving, and the crystal path is slow but repels smaller threats and generates a small amount of power while stationary. You've only got the one propeller, so you can only equip one at a time, but you can switch them whenever you want, it just takes some time to swap the parts, say 30-40 seconds. During this part swap the sub can't move. So you'd have to find somewhere safe, and trying to swap during an encounter would probably get you eaten. Each upgrade could also alter the subs skin in that area, so the normal engine part of the sub could get either a fancier Alterra design, a fleshy or boney look for the Organic, or a crystalline look. which would certainly be a better look than just turning the sub into a giant block of crystal. by the end you'd have a sub that could look totally unique, and people could tell what upgrades you have from a screen shot.

[@Komnene165]

I love how much thought you're putting into this one aspect of your expansion. I also really like the idea of a skills tree. If nothing else it adds an increased amount of customisation which I am always in favour of.

[@neo_8830]

I looove the idea of the vehicle slowly flood, completely stoping working and quickly sinking deeper and deeper until getting crushing by pressure or… by something else… Well yeah, it would be a good idea to make the fear of not having an escape pod !

[@Relic_Dragon]

This whole thing is a great idea! I personally love the trait tree for the Hydra, it adds an element of customizability, and Subnautica needs some more complex systems. The organic path especially makes me excited, it sounds like it could be so cool! Maybe it could do things like repair itself over time using plankton, or even better if you manage to kill something it gives you health. Maybe you could even have a distress call that brings smaller creatures like stalkers crabsnakes ect to help you fight/get away. Great work Aci!

[@Relic_Dragon]

Also, even though Subnautica is not supposed to be a game you kill stuff in, I always love having trophies and such from the things I kill in games. I think it would be cool to reward players who go and manage to kill leviathans (cause they sure will) with something. Even just a mount to put in the living quarters would be amazing.

[@t-wolf8502]

I do like the skill tree idea. It makes the mod more interesting and gives us reason to replay.

[@apokkalypse]

I love everything about this. The skill tree idea is so neat, and would add such a refreshing & fun new way to play the game! The upgrades you've come up with so far are really good, and there's so much potential for even more equally awesome upgrades. I sincerely hope to see this mod become reality, because it's amazing!!

[@TheUnimaterLp]

I think the Escape Pod would be cool, but unnessesary. I think a claw to attach a prawn or a semoth, like the one at the Seetruck could be more usefull. Maybe you could also think of adding an resoure collecting system, maybe like arms at the outside of the sub that have to be controlled manually, so you dont have to exit the sub on your own. Maybe this could also be a mechanic that you have to sty inside the sub, to collect something outside. I like the skilltree idea, but as you ssaid in the video it sounds a bit complicated.

[@KnightandDay33]

I absolutely *love* this concept! It's a small detail, but i'm excited to see what you come up with for a "wakeup alarm" (discussed at 6:20), as this seems like the best opportunity to create tension / memorable moments in the mod. In addition to various lights and sirens, perhaps the ship's AI could also give basic information about the threat when the player takes the helm (eg: "unknown leviathan-class threat starboard, action recommended" or something). Maybe a custom soundtrack could kick in when the situation becomes particularly dire (in the same role "abandon ship" had in the base game) Additionally, this would work particularly well should multiple types of leviathans / behaviours be added (eg: one focused on aggression, another on stalking / confusing the player's systems, etc) All in all, I can't wait to panic when I step on a leviathan's toes

For the skill tree, you can lower the options and add more categories for diversity if you guys have to. But, one very, very very very important thing while developing that feature, just please don't forget to add presets.

[@PyroGam3s]

presets? I assume you mean for fast and easy or quick change of skills for the submarine? Kinda hard to implement that when you have to walk to the panel on the wall to set your preferences for the skill tree. It can still have a preset button on there, but i don't think it would be a good idea to add it to the player hud accessible from anywhere. I can see that getting abused a lot.

[@CuteKyuubi]

Literally just the advert style begining got me excited, and an escape pod that jettisons you back to the surface is an awesome idea :D Edit: Also, the skilltree idea is such an amazing idea!

[@alexg963]

For the escape pod, it should transport you to an identical receiving module that the player has to build. To me at least, that makes more sense from a lore perspective than it simply transporting you to this one particular location in the ocean that happens to be safe. And it gives the player the choice of where their end point will be. Also, I love your ideas about the drone module with a 360 display and the “transparent” walls module. The latter reminds me of what we see in a lot of cars today. Maybe you should have cameras around the outside of a hull as an added detail for this module. From a user experience perspective, this transparency idea makes more sense to me in a large, lumbering vessel like the original Cyclops. For a fast and agile sub, the pilot probably doesn’t have to worry as much about the sub’s positioning and clearance. It feels to me that this would be used in largely the same way as the cameras on the Cyclops are, but instead of flipping from one camera view to the next, you’re running between the captain’s chair and the module at the back of the ship. Don’t get me wrong, it would still be cool and useful. I just think it doesn’t make the most sense when you’re quickly moving through the water. Stopping and getting out of the captain’s chair to go check your surroundings breaks that feeling of being in a highly capable ship.

[@DrDandD]

I have spent a few months working on my own underwater survival game with a somewhat similar idea as call of the void and these videos have been great for reference and inspiration, thanks

[@pengine6096]

I love the idea of the anomalies. It might recreate that feeling you get when you explore the wrecks in the main game, like you have to leave the ship and do as much as you can as fast as you can. Maybe on certain floating islands or floating wrecks, you could find fragments which unlock new upgrades in the skill tree. And possibly with the leviathans, they could guard extra-valuable islands or wrecks. One might guard an upgrade which significantly reduces the energy spent, another might give you a shield or perimeter defense system. Anyways, there are my thoughts.

Dang bro this looks absolutely amazing! I really love the new submarine design, it looks perfect! I think it would be really cool to see the tech tree implemented into the Subnautica universe and I'm loving the idea that there would introduce multiple different play styles, for example prioritizing evasion or stealth rather than weapons and defense. I also think that because they majority of the game takes place within the void, when the submarine crashes it would probably start sinking and eventually get to the point where it's too deep to recover, so maybe a set amount of time where your items are recoverable depending on their depth, or something along those lines. Anyway I'm really excited to see what else comes along in the future and how it works out, keep up the amazing work man! 😊

[@user-su1zh7fx3x]

[@phcgamer8733]

I'd like the skill tree to also be contained in a BIG upgrade module that allows you to swap out skillsets for different missions. First one's free with the sub, any more are somewhat pricey to make. Also maybe have the destruction just break individual rooms, which can cause varying effects based on which room it was and how much it was damaged. For example, a slightly damaged room could consume more oxygen, a moderately damaged room could flood, and a majorly damaged or destroyed room could go haywire and mess things up. Minor to moderate damage can be fixed in situ, but you'll need to go back to base to fix a room that took too much damage.

[@contra8053]

So about the skill paths, It really is up to you. There is something to be said about making your mod too separated from the original mechanics but a lot of mod developers just want to make something as crazy as they possibly can. It would take a lot more development to make the tech tree than just making standard modules and this could easily add another month to the mod's release. Personally I think you should start with standard modules and then add tech trees where you want in later patches.

I think the skill tree idea is pretty good... a bit of complexity in exchange for more customizing sounds good to me. Personally I think having a new vehicle feel and play differently should be a main concern for any mod that adds one, a skill tree is sure to achieve that feeling of being different and unique. As for your question on how the submarine should sink, I don't have much of an opinion, it could be either of the three options and I would be happy with the result regardless.

[@Flyry0815]

I really love the idea of researching the fauna and flora to unlock new technology for your submarine, adapting to the environment as you go

[@Voice_from_the_Void]

Breaking wise, I think the ship should slowly flood, making room to hopefully fix the submarine. Then once the whole thing is submerged, it will split into pieces, leaving the 4 main compartments damaged, but still enter-able (Like the cyclops) Also I think the modules may effect this such as the warp drive will explode and leave nothing left. Aquariums may burst so all your fish can escape, Holograms will break and electrify you of you get too close, and maybe if it gets destroyed before the EEL escape pod launches then the pod lays flat and can still be used. This means if your salvaging the wreck and a predator sneaks up on you, you can re-use the pod to escape. As well as this, the pod should be able to be re-packed and re-used if you make another hydra submarine. Maybe im giving too much ideas though.

You're giving a great reason for more people to get into subnautica modding right now!

[@brennenpatterson7974]

Love the idea of the skill tree, though it might make sense to have it only for skills limited to the hydra and have skills that are already in the game still be module based

[@robowyatt398]

I think the best option with the skill tree is to have 2 branches, one for alterra tech, and one for precursor tech, you could do both but it would take vastly more recourses/time/whatever but it would be very good

[@Tsuusetsu]

I like the skill tree. Loving this whole idea.

[@sharondornhoff7563]

That skill tree concept just tripled (at least) the replay potential of this whole project. Love it! 😁

[@LexIconLS]

This expansion may finally get me to go out to the Void. Having nothing to orient myself to is the most terrifying thing about the deep ocean.

[@alishagrenz8549]

Im SO hyped for this mod it seem very cool and i like the skill tree idea

[@GlitchyfrogMusic]

Do it! That concept is what I've missed!

[@ceratoking1872]

I really like the idea of having a tech tree for the submarine, because it gives the players a good reason to go out and explore the void. Maybe there could even be a precursor path, which could be unlocked by cataloging precursor tech in the void.

[@Sharksader]

This is so cool! I really want the Hydra, it would be awesome! Even if you don't get the support for the whole mode I would still love to see a separate hydra mod. Also the skill tree idea is so cool! I would love to see it!

[@lostfater8062]

Tech tree sounds so interesting and brings in a lot of possibilities! Drone also sounds so cool, if you directly controll it! Crystal system is just... wow! Imagine sacrificing potential speed boost from bio tree to have more powerful defence like some weapons, but not too much, just to scare off things, like torpedos, they are kinda useful in og game but prawn suit grappling hook + armor combo is still better, not to mention gas pod things. All in all I like all of your concepts! Brings back the fear of unknown again. Also warning screen to dead zone also sounds just great! As for thinking, as people suggested below, a combo of old and new cyclops with flooding, explosion and wreck. All in all I LOVE how it looks, so keep developing no matter what!

[@mangaman1215]

The skill tree sounds amazing, I think it would be great to have it in the mod

[@Izawwlgood]

Youve made better assets than were found in BZ. Please keep making cool craft like this for mods! Single upgrade slot is a little tricky though - we'll want to use the map, warper, and probably take home local fauna.

[@Benn25]

With this incredible content, the bar is set even higher for the devs to surpass for subnautica 2.

[@ghostlycoma4049]

I'm so excited to see the skill upgrade tree for the hydra!

[@bellag3293]

The commercial alone is just fire 🔥 cannot wait for this expansion 😭🤩

[@jurnikar]

I'm a big fan of the "Skill Tree" idea, love it!

[@TheGrifter42]

I think the one modular upgrade could be made more interesting by having it be a Fabricator that can build each of the different upgrades. So instead of choosing which one you want at a base, you can choose what you want on the fly, but have to wait for it to build/ have it cost power. That way if you really want a place to store some fish you can, but you’d have to lose your map. Or imagine the stress of trying to avoid a leviathan for long enough for the fabricator to finish building a warp drive/escape pod to escape. Otherwise I feel like most people will just pick one upgrade and use that the entire game. Maybe going down the different tech trees can increase the time for certain upgrades, or make the ship specialized for certain aspects. Like the organic ship would be better at hiding/interacting with the environment while the tech side would be more about defense/escape. Maybe even a Precursor ship for offense so we can finally use the beam weapons from the first game. BUt only if we are being evil or something haha
