Video: Floating Island farming run, lifepod sweep, wreck exploration, and base expansion (no commentary)


I had a lightbulb moment today. I’m fed up of chasing fish.

Every time my hunger dips, I stop what I’m doing, grab the knife, and head outside like I’ve never planned further than the next five minutes. It works. It keeps me alive. It also feels temporary.

The island has fruit. The fruit grows on trees. Trees can be replanted.
The solution has been sitting there the entire time.

If I’m here for the long haul, I need to act like it.

I headed back to the island with one job: harvest what I need and leave. No sightseeing. No heroic dives. Just infrastructure.

As soon as I arrived, I noticed a distress signal directly below the island. Of course there was. I added it to the list and focused on the plants first. Priorities.

I moved through the vegetation carefully. Some of it looks useful and isn’t. Then I found the Bulbo Trees.

Knife out. Controlled hits. Samples collected.

Once cut, they’re on a timer. That’s all I could think about as I made a quick detour down to the lifepod beneath the island. Inside, I picked up a PDA that helpfully informed me the Aurora meeting point was… the island I was just standing on.

Great. Glad we cleared that up.

I didn’t hang around. Back to base.

Titanium gathered. Indoor growbed fabricated. Crops planted immediately. No hesitation.

I stood there longer than I expected, watching them settle into place. It felt different. Less scrambling. More planning.

If this works, food stops being a daily chore. Water still needs attention, but solving one problem at a time is how this becomes manageable.

With farming underway, I checked my signals properly. Two lifepods stood out. One near the Aurora. Another roughly four hundred metres away and one hundred metres down.

I followed the first coordinate carefully. Adjusted for the compass. Reached it.

It was already looted.

I’ve clearly been there before. I don’t remember recording it. At some point in the past, I must have visited, taken what I could, saved, and moved on. Not ideal. From now on, cleared pods get marked properly.

On the way to the second lifepod, I found a wreck and went inside. I can’t help myself. Inside, I found a Battery Charger fragment and another Bioreactor fragment.

The charger is the real win. I’ve been rationing batteries like they’re rare artefacts. One more fragment and that changes completely.

The second lifepod was intact but empty. I had a small laugh at how it had all ended. The ocean has a sense of humour. I took what I could and left.

Back at base, I decided to expand. A tunnel. Another room. The fabricator and I had a brief disagreement about placement, but eventually it cooperated.

The base feels less like a crash shelter now and more like something intentional. At the same time, hull integrity keeps dropping with every addition. The bigger it gets, the weaker it becomes. Reinforcement is climbing the list quickly.

The crops are growing.

That alone changes the tone of everything.

I still need to head back to the Aurora and see what’s waiting in the Captain’s Quarters. That will be deliberate. Planned.

For now, though, survival feels… easier.

I don’t trust that feeling entirely.

But tonight, I’m not chasing fish.

I’m growing them out of the equation.

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 9: Beacons, Blueprints, and a First Proper Home

Submerged Log 9: Beacons, Blueprints, and a First Proper Home

Platform: Steam Deck

Video: Beacon run, Mushroom Forest scavenging, and first base module (no commentary)

When you hit a brick wall in Subnautica, the game doesn’t give you a hint. It gives you more ocean.

I’ve stalled out. Upgrades are half-finished, blueprints are dangling just out of reach,
and my “plan” has become a list of things I’d like to do once I stop being poor in titanium.
So I do the only thing left: explore.

My memory is decent, but this planet is an endless blue maze, and I’m done pretending I’ll remember
where anything is. It’s finally time to start using beacons properly.

Beacon Therapy (Mushroom Forest Edition)

I craft a beacon, head out to the Mushroom Forest, and deploy it the second I arrive.
The logic is simple: if the radio nudged me here once, there’s probably something useful nearby.
I name the beacon, mark the spot, and start searching with actual purpose for once.

The theory pays off fast. I find another piece of the Cyclops puzzle, and — more importantly —
the second Moonpool fragment.
That one moment flips the entire run. Base building isn’t a “someday” thing anymore.
It’s now.

Side Loot: Shale Outcrops and Surprise Diamonds

Since I’m already here (and my sense of direction has clearly been outsourced to a beacon),
I start checking what this biome actually offers.

The big win: diamonds in shale outcrops.
That’s the kind of detail Future Me will be grateful for, assuming Future Me survives
long enough to remember why diamonds matter.

Prep Work: Pin Recipes, Build the Tool, Commit to a Location

I head back to the lifepod and start doing the boring-but-important part:
preparation.
I pin the recipes I know I’ll need, craft the Habitat Builder,
and finally accept that I need a home that isn’t a floating tin can with a radio.

Of course, the radio fires off another distress signal mid-planning.
I add it to the list. I already know how that story ends: no survivors,
just another location stamped onto my growing collection of disappointment.

Base Site Picked (Mostly): “Somewhere Between Here and There”

I settle on a spot roughly halfway between my lifepod and the Mushroom Forest.
In theory, it’s a sensible compromise: close enough to my old “base” for convenience,
close enough to the Mushroom Forest for materials and fragments.

In practice, I’m eyeballing distance in open ocean, which is basically the same
as saying I chose the location by vibes.

I place the first module and immediately run into the first real base problem:
power.
No power means no oxygen inside, which is a fun twist for something that is supposed to be a shelter.

Power Decisions: Solar Wins (For Now)

I weigh up options and land on solar. It’s not glamorous, but it’s doable right now,
and “right now” is the only timeframe this planet respects.

I do some early prep for the Moonpool materials while I’m thinking about the future,
but the titanium math is brutal.
I’m going to need a lot more, which means a dedicated scrap hunt is officially coming.

Hatch Installed, Oxygen Not Included

I craft a hatch so I can actually get inside my new base, but until I get power online,
it’s basically a room-shaped hazard.
No power, no oxygen — and my base is currently doing a great impression of a death trap.

I do have an idea for how to work around that if I need to,
but first I want to solve the problem properly.

Radio Upgrade: No More Lifepod Commuting

One small quality-of-life win: I get a radio set up at the base-in-progress.
That way, I don’t have to keep swimming back to the lifepod every time the game
decides to hand me another “go here” message.

I also keep the Seamoth parked close by.
It’s doing double duty as a safety net and a temporary beacon until I can get a second
beacon made specifically for the base location.

Solar Online: First Breath in the New Base

Once the solar panel finally goes up, everything changes.
I step inside my newly powered base and take the first proper breath of “this might actually work.”

It needs a lot of work. It’s barely more than a shell.
But it’s mine, it’s powered, and it’s a start.
Temporary home or not, it’s the first thing on this planet that feels even slightly under control.
