Submerged: A Subnautica Survival Diary – Log 16 | The Descent Begins

Video Entry
The new base is finally operational.
Honestly, I’m pleased with how it turned out. I had a rough vision in my head while building it, and somehow the result actually resembles what I imagined instead of a collection of underwater tubes held together by panic and titanium.
That said, construction was not exactly smooth. The base developed leaks almost immediately after expansion started, which explains why the walls are now covered in reinforcements. I would love to add more windows eventually, but considering the ocean already tried to force its way inside once, restraint may be the smarter option.
The important systems are online. I’ve got hydroponics running, a water filtration unit producing clean water, and a Gel Sack farm outside. For anyone playing along, once you finally find a Gel Sack, hit it with a knife a few times before harvesting it. The seeds can then be planted in an exterior growbed, saving you from repeated trips into increasingly worrying cave systems every time Aerogel becomes necessary.
The Call From Lifepod 2
During the time spent working on the base, another radio message arrived. I deliberately left it alone until this entry. If I’ve learned anything on this planet, it’s that distress calls rarely improve the situation.
This one came from Lifepod 2.
The coordinates placed it roughly 500 metres below sea level, which is now comfortably within Valentino’s range. Since the last entry, Valentino has received a MK3 depth module, allowing him to descend to 900 metres. I also installed sonar. During testing, it picked up a Reaper Leviathan nearby, so at least now I can detect incoming nightmares slightly earlier than usual.
I still had Lifepod 13 sitting on my HUD as well, so I decided to clear that first. Naturally, I got distracted by wreckage along the way, because apparently I cannot pass abandoned technology without investigating it.
The wreck did not offer much, and neither did Lifepod 13. I suspect I had already visited it earlier and simply forgot to remove the marker. Efficient? No. Consistent? Sadly, yes.
Below 500 Metres
Lifepod 2 was exactly as expected: empty.
No survivors. Just another quiet reminder that everyone else who tried to survive this planet appears to have failed.
While using sonar near the pod, I noticed something else nearby. An opening.
Dark. Deep. Wide enough to continue downward.
With Valentino upgraded and the sonar active, I convinced myself this was a good idea.
That confidence lasted until I saw what looked like an enormous crab with an exposed brain. I briefly considered turning back, but I had already come this far, and apparently that now counts as decision-making.
The deeper I travelled, the stranger the environment became. An underwater river flowed through the cavern, with glowing green fog drifting through the darkness. I scanned what I could and picked up anything that looked useful, because if this planet insists on becoming stranger, I may as well keep stealing from it.
The Waterfall Rule
Eventually I found a waterfall.
Years of gaming have taught me that waterfalls are legally required to hide something, so naturally I investigated.
The passage beyond could not take Valentino with it. It looked like there was breathable air inside, or at least something close enough that I was not immediately dying. Unfortunately, I was also sure I had seen a Leviathan somewhere nearby, along with Warpers moving through the area.
Leaving Valentino outside did not feel great.
I parked him as close as I could and went in anyway.
The Structure Beneath The Planet
Behind the waterfall, I found a giant alien structure buried deep beneath the surface.
I looked for a way to power it, scan it, or interact with it in some useful way, but nothing responded. It just sat there in the silence, which was not comforting.
I returned to Valentino much faster than I entered.
Thankfully, he was still there.
By this point, I was around 800 metres down, and it looked like the route continued even deeper. Before leaving, I found something else: a massive skeleton.
The scan identified it as the remains of a Sea Dragon.
That felt like the planet politely suggesting I leave.
I dropped a beacon to mark the route. I can go further this way later, but not yet. I need the ability to go deeper, and I need more than Valentino if I am going to survive what comes next.
New Targets Unaccounted For: 1
Back at base, another message was waiting.
New targets unaccounted for: 1.
I am assuming that “1” is me.
Which means something knows I exist.
That changes things.
The deeper I go, the clearer it becomes that Valentino alone is no longer enough. If I am going to keep descending into these caverns, I need a mobile base. Somewhere to store supplies, recharge equipment, carry resources, and support longer expeditions far below the surface.
And if something down there decides it wants me dead, I would also like something capable of meeting the problem head-on.
So the time has come.
I said I needed to go deeper.
Now I do.
Which means it is finally time to build a Cyclops and a Prawn Suit.
