Submerged: A Subnautica Survival Diary – Log 11: Copper, Caves, and Structural Regret

Submerged Log 11: Copper, Caves, and Structural Regret

Platform: Steam Deck

Video: Base upgrades, lifepod dive to 250m, cave panic, and Seamoth improvements (no commentary)

I was going to chase the black box. Then I remembered the giant alien laser. Priorities shifted.

The plan had been simple: head back to the Aurora, find the black box data, and pretend I wasn’t about to get shot out of the sky by an alien cannon.

Reality check: I’m not leaving this planet anytime soon.

If I’m here for the long haul, the base needs to stop feeling like a damp hallway with ambition.

Bulkheads, Flooding, and The Game Laughing Directly at Me

I started by looking at a bulkhead, because in my head that means “less flooding” and “more responsible adult survival.”
In practice, the game basically laughed and told me to enjoy living in a fish tank.

So I pivoted to the upgrades that actually move the needle:
more power and medical supplies.

Solar Power and the Medkit Fabricator: A Short Story About Suffering

Goal one: another solar panel.
Goal two: a medkit fabricator, because I’m tired of treating “hope” as a healing item.

Then I checked what I needed and immediately had a new enemy: creepvine samples.
Not because they were hard to get.
Because I already had them.
And then I ate them.

So off I went to replace the snacks I shouldn’t have treated as snacks.

Radio Interruptions: Lifepod 4 Joins the To-Do List

Mid-upgrade, I got a distress signal from Lifepod 4, with the helpful advice to wear a radiation suit.
Which is fair.
But I’ve already handled that situation.

So Lifepod 4 gets added to the list of places I will absolutely go to…
once I’m done putting out the current fires I set myself.

Copper: The Myth, The Legend, The Personal Insult

Copper remains elusive.
I’m finding diamonds more often than copper, which feels like the planet is doing comedy at my expense.

All of this because I need copper wire for a computer chip.
Which means the moment I want to build something “basic,” the universe decides I need to earn it.

At this point I’m seriously considering a scanner room, purely so I can stop living my life like a metal detector with legs.

Medkit Fabricator Online (Finally)

Once the medkit fabricator was up and running, I moved on to a quality-of-life upgrade I should have made ages ago:
a beacon.

I named it “base”, because:

1) it is a base

2) I would like to find it again

3) I don’t need to overthink this

Valentino Goes Deep: The 250m Lifepod Run

With “base” now marked like a sensible person would do, I took Valentino for a drive to a lifepod sitting around 250m down.

Naturally: no survivors.
The ocean doesn’t do happy endings.

But I did come away with something useful: a blueprint for a Repulsion Cannon.
I still need a Modification Station before I can get too excited, but I’ll take a win when it shows up.

The Beautiful Cave That Immediately Became A Problem

Next up: a cave near another lifepod location.
The cave itself is gorgeous.
It’s also the kind of place where you realise, mid-swim, that you have no idea where the exit is.

And that’s when I moved “make a beacon” from “good idea” to “non-negotiable survival requirement.”

I eventually found my way back out, and I didn’t drown in a glowing underwater postcard, so that counts as success.

Valentino’s New Problem: He Can’t Go Anywhere Without Taking Damage

Back at base, I had a new priority: hull reinforcement for Valentino.
He couldn’t so much as breathe underwater without scraping something and taking damage.

So I did what any reasonable person would do:
I went hunting for diamonds.
For armour.
On a submarine scooter.
Completely normal.

Eventually I got lucky and upgraded Valentino with:

Hull Reinforcement
Storage Module

Now he’s tougher, roomier, and slightly less likely to come home looking like he lost a fight with a rock.

Next Time (If Copper Stops Playing Hard To Get)

Hit Lifepod 4 (radiation warning acknowledged, thanks)
Seriously consider a Scanner Room to end the copper scavenger hunt
Start working toward the Modification Station so that Repulsion Cannon isn’t just a tease
Revisit the Aurora plan… after accepting I’m probably getting shot down anyway

🌊 Submerged: A Subnautica Survival Diary – Log 5.5: Racing the Sunbeam

5.5

“Rescue was coming. Naturally, that meant it was time to start a new project instead.”

Platform: Steam Deck
Difficulty: Survival
Recording: Lost due to file corruption — because the ocean clearly wasn’t done messing with me.

Author’s Note: Unfortunately, my recording for this session corrupted before I noticed. So this entry is reconstructed from memory — a cautionary tale for all survivors who trust autosave more than their capture software.

Message from the Heavens

It begins with the crackle of static — another message from the Sunbeam. They’ve located a landing site. They’re on their way. Forty minutes until pickup.

Forty minutes until salvation.

Naturally, I decide to ignore the pending rescue entirely and go chase the final piece of the Mobile Vehicle Bay instead. Priorities.

The Hunt for Titanium and Sanity

I swim toward the Sunbeam’s coordinates, eyes peeled for fragments. Just as I’m starting to lose hope — there it is. The final piece.

I bolt back toward my lifepod like my oxygen tank depends on it (which, to be fair, it always does). The excitement of progress pushes me faster than any propulsion cannon ever could. I check the crafting requirements — Titanium Ingot, Power Cell, a few odds and ends I already have scattered in lockers. Easy enough.

And since I clearly have time before rescue, I think, “Why not go bigger?” Enter: the Seamoth. The personal submersible of my dreams.

Building the Dream

The Mobile Vehicle Bay is first on the list. Titanium gathered, ingot forged, power cell crafted from the remains of old batteries. When it finally deploys and floats proudly on the surface, it feels like progress — real progress.

I climb aboard, ready to build my Seamoth, and immediately realise I’ve made a rookie mistake. No Titanium Ingot. Again. The ocean mocks me with its silence as I swim off once more, scavenging every bit of wreckage I can find.

Eventually, success. The Seamoth blueprint completes, and the little sub rises from the water like a gift from the deep. She’s beautiful — and mine. I climb in, listen to the AI purr, and feel an unfamiliar thing: hope.

There’s still time before the Sunbeam arrives. I point my Seamoth toward the landing site. Maybe, just maybe, I’ll make it in time to see the sky light up with something other than plasma fire.

Next: The Sky Burns

I set course for the island, my Seamoth slicing through the water like it was always meant to be there. The radio says twenty minutes until the Sunbeam arrives. The ocean says otherwise.

🌊 Submerged: A Subnautica Survival Diary – Log 5: Scanners, Stalkers, and the Elusive Bay

“Sometimes survival means chasing blueprints you’ll never find and pretending the ocean isn’t full of things that want to hypnotise you.”

Platform: Steam Deck
Objective: Wait for the Sunbeam transmission and maybe, just maybe, build something that floats.

Exploration (a.k.a. Avoiding Impatience)

With nothing to do but wait for the Sunbeam’s next message, I decide to make the most of my surface time. I remember having another lifepod distress signal stored, so I tag it on my HUD and head out exploring. At first, the ocean feels empty — just me, the waves, and a slowly draining battery supply — but that doesn’t last long.

After a bit of aimless swimming, I finally stumble upon the final fragment for the Laser Cutter. I can practically hear the sound of sealed Aurora doors opening already. Victory, thy name is “I can finally cut stuff.”

In the midst of my excitement, I make the questionable decision to scan a Stalker. It could’ve gone wrong in a hurry, but apparently it was too busy minding its own business to care. A rare win for curiosity over self-preservation.

The Hunt for the Mobile Vehicle Bay

With the Laser Cutter blueprints ready, I set my sights on something even more crucial: the Mobile Vehicle Bay. I want my Seamoth — freedom in miniature submarine form. I head toward Lifepod 17 again, the same one that’s been testing my patience since last time.

Luck strikes early — I find two out of three pieces for the Bay in fairly quick succession. Naturally, that’s where the good fortune ends. The third? Nowhere to be seen. I comb the seabed, check every wreck, and even chase shadows thinking they might be fragments. Spoiler: they weren’t.

In true Subnautica fashion, my HUD decides to stop showing the lifepod marker mid-journey. A quick reset fixes it, but it doesn’t help my sense of direction — or my growing frustration. Ten to fifteen minutes later, I’m still empty-handed.

Strange Fish and Stranger Plants

To add to the ambience, I discover a few plants with anger issues and meet a Mesmer — a deceptively pretty fish that freezes you mid-swim while whispering sweet nonsense. The first time it happened, I couldn’t move, couldn’t think, and then suddenly — WHAM. Out of the trance, face-to-face with a glowing fish that definitely wanted me gone.

Thankfully, the Propulsion Cannon was in my hands. A single blast later, and the Mesmer was forcibly introduced to the local wall. Justice served.

Calling It a Night (Reluctantly)

As darkness falls, I decide to call it a day. Nighttime on this planet is truly pitch black, and I’m not wasting my last batteries trying to play deep-sea Marco Polo with blueprints. Still, it wasn’t a wasted trip — I unlocked a few new crafting recipes and gathered plenty of scan data for the databank. Just not the one blueprint I actually wanted.

Tomorrow, the ocean and I will have words. Preferably near the wrecks that have Mobile Vehicle Bay fragments.

🌊 Announcement: Subnautica Will Be the Next Series!

While my Argonian my have fallen, it’s time to look ahead—and downward. Specifically, into the ocean.

I’m excited to announce that Subnautica will be the next full series featured on Survivor Incognito! The series will officially begin in a few weeks, once I’ve reacquainted myself with the controls (because I apparently forgot how to swim, build, and breathe). It’ll fall under the same permadeath-flavoured survival approach as the others, with a few sea-salty twists.

In the meantime, I’ve already launched the Subnautica Maps Page to help new players, returning survivors, and confused PDA AIs alike. Bookmark it, share it, or yell at it when you get lost near the Aurora again.

🎉 Celebrating 1,000 Views!

Also, a massive thank you to everyone who’s visited the blog—Survivor Incognito has officially passed the 1,000 views milestone!

To mark the occasion, I’m doing something a little different… something a little more classic horror. While I’m still getting my bearings with the controls again, you can expect a familiar mansion, limited saves, and enough tension to make a zombie blush. 🧟‍♂️
