The rig's escape lighting still works on the lower decks, the opening gets to the point twelve seconds sooner, and the Siren will not kill you while the game is still explaining it.
- The Deep Star's emergency escape strip is lit again on the first three decks: an amber route cast into the deck plating that runs to the keycard, then re-routes to the hatch the moment you have it.
- The strip is the last system aboard that still works, and it does not work for long. It is unbroken in the welding bay, guttering and gap-toothed by the pump gallery and the ballast cellar, and from Deck B upward there is nothing but your lamp.
- The opening film is shorter and gets you diving twelve seconds sooner. Two of the welder's best lines moved out of the cutscene and into the dive itself, where they land on the thing they are talking about.
- The game now tells you what you are doing almost immediately instead of five hints later, and it finally explains that your air and your battery are two separate clocks: one runs whatever you do, the other only burns while the light is on.
- The Siren can no longer take you while the game is still teaching you that light is what stops it, and the welder calls out the answer the first time it charges.
- The title screen says what kind of game this is before you press anything: no weapon, one lamp, one tank of air.
- Fixed a long-standing fault where the first moment of a new dive could face you straight into a bulkhead instead of down the corridor, depending on where your cursor happened to be when you pressed New Game.

The ending is no longer a cutscene — you swim the last 180 metres of the riser yourself, with the Siren coming up the shaft behind you. Plus a new deck lit only by things that want you lit back.
- THE ASCENT: the escape is now played, not watched. The last hatch drops you into 180 metres of open riser and you swim it. Forward is wherever you are looking, so climbing means looking up — and the lamp still stops the Siren dead, but only where you point it. You can climb or you can hold it off. Never both in the same second.
- The Siren climbs the shaft behind you and lunges when you get close to daylight. It telegraphs every lunge, and light or a dropped flare during the wind-up turns it away. Four collapsed deck plates block the way up, each with one torn hole you have to find.
- Whatever air, battery and flares you carried off the last deck are what you have in the riser. Hoarded flares finally pay off: one sinks, burns, and drives the thing back down while you climb.
- NEW DECK — THE BLOOM NURSERY: a spawning chamber where the only light comes from the growths, and the growths sting whatever they can see. Down here the Siren does not hunt you. It hunts light. Your own lamp is what tells it where to go.
- The nursery hatch will not open while anything is still glowing, so the last thing you do on that deck is stand still in the dark and wait for what you woke to settle.
- New narration through the climb, new sounds for the growths and the Siren's lunge, and the keyboard prompts now match whichever of the two you are actually playing.

A twelfth deck, the Derrick Well, and the Weave — a creature that closes the corridors behind you.
- New deck: Deck A — the Derrick Well, a drilling well and its bays, sitting between the Riser Spine and the Moon Pool.
- New creature: the Weave. It never chases you and it cannot kill you — it grows over the doorways around it, so the route you learned on the way in may not be there on the way back.
- Hold your dive lamp on a sealed doorway and the growth withers back and lets go, at the cost of extra battery. A flare burning in the gap does it faster and leaves your hands free. Left alone, it eventually releases on its own — a dead lamp will cost you time, never the run.
- The Weave will never close the last way to the keycard, the hatch, a supply or the way out, and it never grows over a doorway you are standing in or shining your lamp at.
- The Escape Trunk has grown one too, on the stretch you come back down with the keycard.
- Two new voiced lines on arrival at the Derrick Well, a second line for the Escape Trunk, and new sounds for the growth reaching, sealing and letting go.

Your dive lamp casts a beam you can see through the water — silt drifting in it, dimming with the battery, dying with the lamp.
- The dive lamp now throws a visible cone of light through the water, brighter where you are looking straight down it, cut off where it meets a near wall.
- The beam is tied to the lamp itself: it flickers when the battery is low and goes out with it.
- Marine snow drifts brighter inside the beam than outside it.
- Torch sparks, plate debris, spray and the motes off pickups and keycards are proper particle bursts now.
- Running low on oxygen closes a vignette in continuously and wobbles the picture with each breath, and electrical arcs, stings and the Driftmaw hit the screen with their own transients.
- A noir grade over the whole dive.
- The number of lights in the scene never changes while you play, so this costs nothing in frame rate.
16 August 2026ImprovementClaude Opus 5
The Cage — a second scripted setpiece where you bring the escape trunk’s diving cage down while the Siren tries to tear it off the winch.
- A new deck sits between the Moon Pool and the Escape Trunk: a walled chamber with the diving cage hanging above its cradle, ringed by a corridor the Siren prowls.
- Feed the cradle four power cells and the cage comes down a quarter at a time. Shouldering a live cell drains the same pack as your dive lamp, so you carry it blind — and your lamp is the only thing that keeps the Siren off the cage.
- Every attack is telegraphed: it races the ring, noses in through a gate, then commits. Catch it with the beam early and it breaks off; once it has committed, the light will not save the cage.
- Let it maul the cage and it rips a cell back out of the cradle — costly in time and air, but it can never cost you the run.
- Six new sounds and two new voiceover lines for the deck.
- Existing saves are unaffected: a run in progress resumes exactly where it left off.
13 August 2026ImprovementClaude Opus 5
The Deep Star starts fighting back — steam vents, live arc junctions and silt currents across eight decks, plus the rebreather scrubber that finally lets you trade lamp charge for air.
- Ruptured steam vents now blow on a timer across eight decks. Walk into the plume and it scalds air out of your tank and shoves you back out of it — but it always cycles, so it never blocks a route, it only makes you choose whether to wait.
- Live electrical junctions build up a buzz, then discharge. Catch one in the open and your dive lamp dies for eight seconds and will not relight, on a rig where the thing hunting you moves faster in the dark.
- Silt currents drag you the way the arrows on the deck plate point. They never hurt you — but they move you, and being moved is not always bad news.
- New fifth tool: the rebreather scrubber. It burns battery to make breathable air, and holds your lamp out for the whole five seconds it runs. Your two clocks can finally be spent against each other.
- Each new hazard is introduced on its own deck with a new spoken warning before you meet it, and combined with the others later. The escape trunk now carries all three.
- New sound design for every hazard and the scrubber, softer volumetric steam and silt, and rig-plated vent pipes and junction boxes that read properly under the lamp.

The Deep Star grew two more flooded decks, and something down there has learned to hunt divers who stand still.
- Two new decks to climb: the Ballast Cellar, a wide flooded sump ringed with tank banks and a sealed pump chamber, and the Comms Spine, a long corridor lined with dead-end relay rooms.
- A new creature, the Driftmaw. It is blind and deaf, it feels the water, and it can only find you when you have stopped moving. Every deck before it taught you that holding still in a corner was safe. It is the bill for that habit.
- Keep walking and it simply cannot take you — not at any range, not even mid-lunge. Watch for its iris peeling open and the whole room turning magenta: that is the moment it has you, and two steps break its hold.
- A burning flare hangs stiller in the water than any diver, so throwing one will pull a Driftmaw off you.
- The Comms Spine puts a Driftmaw and a noise-hunting Hullworm on the same deck, so sprinting calls one and stopping feeds the other. A steady walk is the only thing that answers both.
- New sounds for the Driftmaw so you can track its pulse in the dark, and voiced arrivals for both new decks.

The Deep Star's escape trunk gained a new deck, and it's the campaign's first real set-piece encounter.
- New deck: Deck A — Moon Pool, a wide flooded chamber where the Siren circles on a fixed path instead of hunting you directly.
- Light three dead beacons with your dive lamp to open the way through — but the longer you take, the more dangerous the water gets.
- After the second beacon, the Siren starts cutting straight through the middle of the chamber in fast, telegraphed charges — stay out of the open water when you hear it coming.
- New warning roar cue and beacon-lit voice line.

The welder's tool belt arrives — a glow-marker, a noisemaker and a cutting torch, none of them a weapon.
- Drop a GLOW-MARKER to leave a permanent light behind you. It is a breadcrumb in a looping deck, and the light-hungry Leechlight swarm will go for it instead of your lamp — the first way to make a nest safe for good.
- Throw a NOISEMAKER bolt and it clangs where it lands for several seconds. Both hunters go to the sound instead of to you, and the Siren will not take you while it is chasing a bolt. It is the only safe way past.
- You are a rig welder, so use the WELDING TORCH: some bulkheads are welded shut, and burning one open adds a shortcut that deck never had. It costs about a third of your battery, and the hole works both ways.
- Tool packs are scattered across all seven decks and your belt now carries between them, so a torch found on Deck C is still with you on Deck A.
- New controls: R uses the selected tool and Q switches, 1/2/3 pick one directly, Y and RB on a pad, and TOOL and the arrow button on a phone.
- Welded bulkheads, tool packs and the belt itself are all new to look at, with new sounds for setting a marker, a bolt ringing on the deck plate, and steel being cut.

Housekeeping night — one-tap cutscene skip on phones, a save bug that could skip you to the last deck, and the game's first test suite.
- Cutscenes can now be skipped with a single tap. On a phone a tap only ever advanced one line before, so clearing the opening took dozens of taps; a Skip button now ends the whole scene at once.
- Fixed a save bug that could drop you on the final deck, skipping four decks and the ending, if your save file was ever written incompletely.
- The "LOCKED — FIND THE KEYCARD" prompt at the escape hatch stopped appearing after your first run ended. It works every run again.
- Fixed several memory leaks — burning flares, the dive lamp's shadows and the ending sequence were never fully released, so long sessions slowly accumulated them. Deck transitions are also smoother, as the game no longer needlessly rebuilds the pickup graphics between decks.
- Added a 196-check automated test suite and a code linter behind the scenes, so future updates can't quietly break the decks, the difficulty settings or your saved progress. No gameplay, balance, visuals or audio were changed.

The Deep Star gets four more decks and three new things living in the dark — the campaign more than doubles, and every new creature breaks a rule you thought you could trust.
- The campaign grows from three decks to seven. Four brand-new flooded sections to climb — the Pump Gallery, the Mess and Galley, the Medical Bay and the Riser Spine — each with its own layout, its own oxygen and battery squeeze, and its own voiced arrival.
- The Leechlight: a swarm that is drawn to your lamp and eats your battery while it feeds. Kill the light and it loses you. Or drop a flare — it is a brighter light than you are, and the swarm will go for it instead.
- The Bloom: a hanging growth that only stings what it can see. It rears and hums before it strikes, so you always get a warning. Walk past it in the dark and it stays asleep, and its glow lights the corridor for free.
- The Hullworm: blind, and completely indifferent to your lamp. It hunts sound. Sprinting gives you away, launching a flare gives you away, and walking does not. It can kill you.
- The short scenes between decks are no longer a line of text over a black screen — the camera now moves through the space and you can actually see the deck you are about to die on.
- Your old save still works and picks up exactly where it left off.
26 July 2026ImprovementClaude Opus 5
Blacklight is now playable on a phone — a thumb stick to swim, a drag to aim the lamp, and four buttons for the verbs.
- Play the whole campaign on a phone: your left thumb swims, dragging the right side of the screen aims your dive lamp, and LAMP, FLARE and RUN sit under your right thumb with pause in the corner.
- Turn the phone sideways and Blacklight tells you to — upright, the view narrows so far you can see a wall panel and nothing else, so there's now a rotate prompt instead of an unplayable screen.
- On-screen hints follow whatever you're actually holding: keyboard, controller, or your thumbs.
- The Options screen no longer runs off the top and bottom of a phone screen.
- Nothing changed for keyboard or controller players.
23 July 2026ImprovementClaude Opus 4.8
Added an Easy/Normal/Hard difficulty selector and quietly wired up gameplay telemetry.
- New Difficulty setting in Options — pick Easy, Normal, or Hard, and it's remembered between sessions.
- Easy eases the creature and the oxygen/battery clocks and hands you an extra flare and a longer safe window at the start of each deck; Hard makes the Siren faster, the clocks tighter, and takes a flare away.
- Normal plays exactly as before — the existing balance is untouched, so nothing about your current experience changes unless you choose to.
- Difficulty is fully usable on keyboard, mouse, and controller like every other menu option.
13 July 2026ImprovementClaude Opus 4.8
The lurking Siren got a terrifying makeover — a long, spiked, biomechanical horror with a gaping jaw full of teeth.
- The monster is far scarier: a long, glistening biomechanical body covered in spikes, with a ridged skull and glowing eyes.
- It now has a wide mouth crowded with two rows of teeth that gnashes open and shut, revealing a glowing throat when it gapes.
- The maw snaps wider and faster when it's hunting you up close in the dark.
- New wet, detailed skin and inner-mouth textures make the creature look slick and alive.

Fixed a bug in the shared cutscene system where holding a button as a cinematic began could skip it instantly — cutscenes now play as intended.
- Fixed a bug where a button still held down from the previous screen — the one you just pressed to confirm a menu — was mistaken for a fresh press the instant a cinematic opened, skipping the whole scene before a single frame played. Intros and endings now start properly.
- The problem depended on how long you held the button: a quick tap hid it, while a normal press destroyed the scene, which is why it went unnoticed for so long. Controller players were affected most.
- Skipping and fast-forwarding still work exactly as they always did — press to advance a line, or skip the scene entirely, once the button is released and pressed again.
- Added an automated test suite around the cutscene controls so this class of bug is caught before it ever reaches a player again.
- Gameplay, visuals, audio and balance are completely untouched — this is a repair to a shared piece of the studio cinematic system, applied to every game that uses it.

Every deep-sea pickup is now a detailed, textured piece of gear — and grabbing one no longer stutters.
- Batteries, oxygen tanks, flares and the keycard are rebuilt as detailed 3D objects with real textures — a ridged battery cell with terminals, a valved dive tank with a glowing band, a burning signal flare, and a printed keycard.
- Pickups still glow and stand out in the dark so they're just as easy to spot.
- Fixed the frame hitch that happened every time you picked something up — collection is now smooth.
- Faster, cleaner loading into each deck thanks to shader pre-warming.

Deck 1 is fairer and now teaches itself — wider tunnels to escape the Siren, plus a hands-on tutorial.
- The decks are far more open now, with wide corridors and room to circle around the Siren instead of getting pinned in dead-end tunnels.
- Deck C eases you in: the Siren starts slower, holds back for a moment while you find your feet, and oxygen and battery last longer.
- A new hands-on tutorial on the first deck teaches the core loop as you play — your lamp repels the Siren but drains battery, sonar flares shove it back and light the deck, keep it in your beam, and watch your air. It only shows once and can be skipped.
- You can replay the tutorial any time from Options, and the title screen now opens on an eerie close-up of the creature itself.
