Island Castaway Lost World Chapter 12 Upd May 2026
Given the confusion around updates (the game is several years old), here is the exact method to ensure you get the patch:

For Android Users:
For Amazon Fire users: The update is usually 2 weeks behind iOS/Android. As of this writing, it is "Under Review."
The narrative in Lost World has always been light—notes in bottles, journal entries, the occasional ghost of another survivor. But Chapter 12 drops something heavier. A discovery. Not a treasure, not an escape route, but a question.
Without spoiling: you find evidence that someone else was here. Not recently. Not accidentally. Deliberately. And they didn’t leave because they couldn’t. They left because they chose not to.
That line—a single sentence in a weathered journal—changed how I see the whole game. Am I trying to escape? Or am I trying to prove I don’t need to?
By Chapter 12, you’ve stopped being a castaway. You’re an engineer, a botanist, a reluctant cartographer. You’ve memorized which bushes drop rope and which drop nothing but disappointment. You’ve named the boars. (RIP, Gregory.)
But this chapter introduces a quiet horror the earlier ones only hinted at: diminishing returns.
The resources you once gathered in ten minutes now take an hour. The tools you relied on degrade faster. The island, which once felt like a puzzle, now feels like a conversation—and it’s telling you to slow down.
There’s a moment in Chapter 12—and if you’ve played it, you know exactly which one—where you realize you’re not surviving against the island anymore. You’re surviving with it. And that’s a far stranger kind of game.
Kana takes a backseat in this chapter (though she still appears in cutscenes). Your new companion is Maya, a cartographer from a lost Polynesian-like culture who was preserved in a stasis crystal for 500 years. She helps you decode the Precursor language.
Before you dive into the Island Castaway Lost World Chapter 12 UPD, keep these survival tips in mind:
Absolutely. The Island Castaway Lost World Chapter 12 UPD revitalizes the game with a stunning new biome, emotional story beats, and meaningful choices.

In The Island Castaway: Lost World, players have long awaited an official update for Chapter 12. While the game originally planned for 18 chapters, official development by Awem famously stalled after Chapter 11.
Because the developers have not released new story content since roughly 2015—with updates in 2018 and 2021 focusing only on bug fixes—the community has largely turned to fan-created content and "Fanfic Wikis" to continue the story. The Mystery of the Missing Chapter 12
Players who finish Chapter 11 receive an in-game message stating that "more chapters" are coming soon. However, this update never materialized, leaving the castaways stranded after crashing on a new, larger island in Chapter 10.
For those looking for the "Chapter 12 experience," the Island Castaway Lost World Chapter 12 Fanfic Wiki offers a deep, community-written continuation of the plot. Community Walkthrough: Fan-Generated Storylines
Since no official Chapter 12 exists, the following summary highlights the primary fan-fictional quests and plot points often discussed in the "Lost World Chapter 12 Upd" community:
The Sickness of Amelia: The story picks up with Amelia falling dangerously ill, forcing the group to find new ways to heal her.
Nicole’s Quest for Ingredients: One of the first community-driven "quests" involves Nicole collecting watermelon seeds, kiwis, sugar cane, oranges, and coconuts.
The Beach Bunker: Tom works on a specialized cover for a beach bunker to protect the group from hyenas, requiring lumber, liana, rocks, and rubber.
Agriculture & Fishing: Sophia and Phato focus on expanding the food supply, with Sophia planting seeds while Phato demonstrates advanced fishing techniques for eels and squid. Survival Mechanics & Tips
While waiting for official content, players can master high-level gameplay mechanics present in the later chapters of the available game:
Defeating Bosses: To take down the giant crab, you must use a fully upgraded bow and keep a large stock of dishes to restore health during the fight.
Upgrading the Quarry: Some players face challenges with collapsed cave passages and must prioritize upgrading the quarry in the Cave of the Ancestors to gather sufficient stone.
Managing Animals: Boars and hyenas are persistent threats. Boars can be outrun, and they typically won't follow you onto bridges or into certain safe zones. Current Status of the Game
Here’s a concise, engaging chapter (Chapter 12) continuation for an "Island Castaway: Lost World" story. I assumed a survival-adventure tone with mystery and character development.
Chapter 12 — The Glass Ridge
The morning fog clung to the palms like a secret. Mara woke to the song of something she didn’t recognize — quick, metallic chirps coming from beyond the lagoon. For a moment she lay very still, listening; then she slipped from the lean-to and padded barefoot across damp sand toward the sound.
At the ridge where the island’s black stone met the sky, the air shimmered. Mara’s breath caught. Below, the lagoon’s surface fractured into a grid of gleaming panes, like a broken mirror stitched tight to the earth. The phenomenon pulsed faintly, sending ripples of light across the underside of the cliff.
“You see it?” Tom called from behind, voice low. He had climbed up while she slept, hauling with him the salvaged rope and an old brass compass that no longer pointed north. He squinted, hand shading his eyes. “Never seen anything like this. The map said glass ridge was a myth.”
Mara swallowed. The compass needle vibrated and then steadied, aligning with an angle that made no sense. The chirps were clearer now — not birds. Small, deliberate clicks, like stones tapping a rhythm.
They descended cautiously to the lagoon’s edge. The water was neither fresh nor fully salt; it tasted like rain mixed with iron. Embedded in the lagoon’s floor were translucent slabs that fit together with impossible precision. When Mara pressed her hand to one, it gave, like solidified water, and a thin filament of blue light traced across her palm.
“Technology,” Tom whispered. “Or something that looks like it.”
From the ridge behind them came a whisper of movement. Ana, the island’s quietest tracker, emerged carrying a bundle wrapped in woven leaves. “Found this near the mangroves,” she said without preface, laying the bundle on the slab. Inside, taped to a cracked leather journal, was a small brass device — a lens set in a ring of black metal. Symbols etched into it matched the markings on the compass.
Mara opened the journal with a thumb that trembled. The handwriting was uneven, spattered with salt stains and age. The last entry read: We thought we had been abandoned. We found the glass. It remembers.
The slab beneath them hummed louder, resonating with the words as if the island understood the name.
“That’s not just a surface,” Ana said. “It’s memory. It keeps… things.”
They experimented. Tom laid his hand flat; images bloomed beneath the transparent stone — a quick sequence of scenes: a boat’s hull tearing through furious waves, a laboratory’s cold light, a map with a red X, a man shouting orders in a language none of them knew. The visions were fragments, each dissolving when any of them tried to hold on.
Mara felt dizzy with the flood of foreign lives. One image clung: a child pressing a small toy soldier into a woman’s palm — a quiet promise — and the woman’s face turned toward something bright enough to erase everything else.
“Memories trapped in the glass,” Mara said. “Lost people, or pieces of them.”
They argued the risks. Could the slab be a record, an archive of everything the island had witnessed? Or a trap, a lure for those who’d come seeking answers? The brass lens might allow one to focus the images, isolate a single memory. But the journal warned of obsession: once the glass gives you a life, it wants you to step inside.
Night fell, and with it the lagoon’s glow intensified. The panes lit from within, not with electric light but with the slow bioluminescence of depth and time. As they sat in the reflected glow, a new sound rose from the ridge — low and rhythmic, like someone tapping out a language.
Mara lay the brass lens over the nearest slab, heart pounding. The lens fit its groove perfectly and the symbols on the journal matched those on the metal. When she looked through, the glass no longer offered fragments; it opened a corridor of a single remembered evening: a laboratory with a window overlooking a jungle that looked like their island, but younger, raw as an open wound. The camera panned to a woman at a desk whispering into a recorder. Her voice, muffled, said, “If anyone finds this, keep the child safe. He remembers too much.”
Mara staggered back. Tom grabbed her arm. “A child… someone we could still help?”
A breeze moved across the lagoon and the panes dimmed, sealing the corridor. The device clicked in Mara’s hand, hot and sinister.
They slept fitfully, each haunted by flashes of lives that might have been theirs. At dawn, Ana was gone. A strip of crushed fern and two small footprints led toward the grotto where the mangroves tangled like fingers. When Mara and Tom followed, they found Ana at the mouth of a cave, staring into darkness. She held up the leather journal; a new page had been added overnight. The handwriting was small and hurried: She left to find the child.
“No,” Tom said. “We don’t split up.”
But Ana’s eyes were set like flint. “We can’t leave a memory with a missing name. If the island is a book, someone wrote a story that’s unfinished.”
They argued, then agreed: they would search together, but cautiously. They strengthened their packs, took the compass-lens, and marked the path with carved notches. The island answered them with weather—thin rain like scattered pearls, then sun that turned the glass ridge to a blade.
The trail took them into a hollow where the air was cool and smelled of old paper and iron. Roots arched overhead, forming a tunnel carved by something deliberate. The ground was embedded with shards of the same translucent material, each shard ringing faintly when brushed.
At the tunnel’s end, the earth opened into a chamber. In its center sat a cradle carved from driftwood, slick with salt but otherwise untouched. Within it, a small cloth bundle stirred. island castaway lost world chapter 12 upd
Mara stepped forward, hands steady now despite the trembling in her chest. She unwrapped the cloth. Inside was not a child, but a toy soldier made of the same black metal as the lens. Its eyes were tiny orbs of glass. The soldier’s chest held an inscription in a hand the same as the journal: FOR THE KEEPER.
A click sounded. The chamber’s shards flared, and the memory-images returned not as visions but as voices — overlapping, urgent, pleading. The island was speaking in a chorus of trapped lives. Mara realized, with a cold certainty, that the glass did not merely record; it kept the echoes of those who had tried to own it.
“That toy…” Tom said. “It’s a key.”
The brass lens vibrated in her palm. The compass needle swung violently, then aligned into a new direction — not north, but toward the island’s heart.
They had a choice: try to free whatever was trapped, risking that the island would latch onto them, or leave the toy soldier buried and walk away with only questions. Mara looked at Tom, then Ana. Their faces were pale but resolved.
“We finish this,” she said.
They did not know what finish meant. The island had a vocabulary of its own: glass and memory and hunger. But now they had the key, a tether to someone who had been lost and a purpose that felt heavier than survival. As they turned back toward the ridge, the lagoon’s panes hummed louder, like applause or warning.
Above, the sky cleared. For the first time in weeks, Mara felt a thin, hard thing that resembled hope.

🌴 ISLAND CASTAWAY: LOST WORLD – CHAPTER 12 UPDATE BREAKDOWN 🧭
Survivors, the wait is over! Chapter 12 of Island Castaway: Lost World has washed ashore, bringing new mysteries, tougher challenges, and a deeper dive into the island’s forbidden past. Here’s everything you need to know.
Kaelen and Mira escaped the crushing vines of the Carnivorous Grove. Severely dehydrated and losing hope, they stumbled upon a river that glowed with an unnatural bioluminescence. Following it upstream, they discovered not an exit, but the entrance to a massive geothermal vent system—and carved into the stone archway above it, a symbol matching the brand on Mira’s arm.
The heat hit them first. Not the humid, suffocating blanket of the jungle, but a dry, chemical burn that stole the moisture from their eyes. Kaelen held up his torch—a fresh branch dipped in phosphorescent sap—and watched the flames ripple sideways.
"There's a draft," he whispered.
Mira pressed her branded arm against the stone. The symbol, a spiral within a jagged sun, throbbed with a dull ache. "It knows we're here," she said, her voice hollow. "The island… it's breathing."
The tunnel sloped sharply downward. What had begun as a narrow fissure in the limestone widened into a cathedral of basalt columns, each one carved with scenes of a civilization that should not exist. Human figures—no, not human. Taller. Thinner. With elongated fingers and eyes represented as empty circles—stood before altars. They were feeding something. Offering something.
"What is this place?" Kaelen asked, though he already knew the answer.
"The first temple," Mira replied. "The ones who came before the castaways."
They moved deeper. The updraft grew stronger, warmer. It smelled of sulfur and ozone, like lightning striking wet iron. And then they heard it: a low, rhythmic hum, less a sound than a vibration in the marrow of their bones.
The tunnel opened into a vast chamber. The ceiling was lost in darkness, but the floor… the floor was a mosaic of bones. Thousands of them. Human, avian, reptilian, and others that defied classification, all fused together by a smooth, glassy substance that pulsed with a soft amber light.
In the center of the chamber stood the Heart of the Updraft.
It was not a machine, nor a natural formation. It was a sphere of interlocking obsidian rings, each spinning at a different speed, suspended above a pit that exhaled the planet’s molten breath. Every few seconds, a ring would align, and a beam of compressed air and heat would shoot upward into a vertical shaft carved through the rock—the source of the updraft that had guided them here.
"They didn't build this," Kaelen breathed. "They found it."
Mira stepped onto the bone-mosaic floor. It did not crack. Instead, the amber light beneath her feet brightened, tracing her path like a river of honey. "The journal from Chapter 4 mentioned a 'control nexus,'" she said. "The previous castaway—the one who went mad—he wrote that the island isn't a prison. It's a regulator."
Before Kaelen could ask what that meant, the updraft changed.
It shifted from a steady column of warm air to a pulsing, directed gust. It swirled around Mira's arm, wrapping the brand like a living serpent. She cried out—not in pain, but in shock. The spiral symbol on her skin peeled away, lifting into the air as a ribbon of black smoke, and then reformed itself in the center of the spinning rings.
The chamber trembled.
A deep, guttural roar echoed from the bone pit below—not the island, but something in the island. Something that had been sleeping.
"Kaelen," Mira said, her eyes wide and reflecting the amber glow, "I didn't activate it. The brand was a key. And now the lock is open."
The obsidian rings began to spin faster. The updraft became a shrieking gale, tearing at their clothes, lifting smaller bones from the mosaic and hurling them against the walls. Through the howl of wind, Kaelen heard another sound: voices. Not human voices. Overlapping, chattering, ancient. They spoke in a language that made his teeth ache.
One word repeated: "Kor-Veth."
Mira grabbed his arm. "The journal! The mad castaway wrote that name. 'Kor-Veth is the warden. Do not let it wake.'"
Too late.
From the pit beneath the spinning rings, something climbed. It had no fixed shape—a shifting mass of volcanic glass and calcified coral, with too many limbs and a single, vertical slit that glowed with the same amber light as the floor. It pulled itself up using the bone mosaic as handholds, cracking millennia of fused remains like dry leaves.
The updraft wasn't a natural phenomenon. It was its breath.
Kaelen pulled Mira behind a fallen column. "We need to reverse this. How did the previous castaway stop it?"
"The journal didn't say he stopped it," Mira whispered, trembling. "It said he ran. And then it said… 'The only way to seal the warden is to offer what it lost.'"
"What did it lose?"
The creature—Kor-Veth—turned its slit-eye toward them. The amber light scanned the chamber until it fixed on Mira. On her arm, where the brand used to be. A sound emerged from the shifting mass, a rasp like grinding stones: "The vessel returns the key. Now the vessel must return the blood."
Kaelen's mind raced. The geothermal vent system, the updraft, the bone mosaic—it wasn't a temple. It was a cage. And the brand on Mira's arm wasn't just a key; it was a leash. The island had chosen her not to be a survivor, but a sacrifice.
"No," Kaelen said, stepping in front of her. "Find another way. There's always another way."
Kor-Veth lunged. Not fast—its movements were slow, ponderous, like a landslide given intent. But the updraft shifted with it, slamming Kaelen against the column hard enough to crack a rib. Mira screamed and scrambled toward the opposite side of the chamber, where a narrow ledge led to the vertical shaft—the path of the updraft itself.
"I can climb it!" she shouted. "The air current is strong enough to carry a person upward. It might lead to the surface!"
"It might cook you alive!" Kaelen shouted back, gasping for breath.
Kor-Veth extended a limb of jagged obsidian toward Mira. She dodged, but the limb changed direction mid-swing, adapting. Learning. The warden wasn't mindless. It was patient.
Mira looked at Kaelen, then at the spinning obsidian rings, then at the brand-shaped scar on her arm. "The journal also said," she called out, "that the castaway who built this place—the First Builder—left a failsafe. A second key. But it's not a brand. It's a choice."
"What choice?!"
She pointed at the bone mosaic beneath their feet. "These aren't just bones. They're everyone who refused the choice. The island doesn't kill randomly. It offers. Give the warden what it wants, or become part of the floor."
Kaelen looked down. The amber light was spreading, reaching up his legs like frozen honey. He could feel it tugging at his soul, not his body. The mosaic wanted to add him to its pattern.
He had seconds.
"The updraft!" he yelled. "You said it's breath. What if we change what it breathes?"
Mira's eyes widened. She understood. The rings controlled the airflow. If they could jam the rings—stop their alignment—the updraft would collapse, and without the draft, Kor-Veth would lose its mobility. It would sink back into the pit.
Together, they ran toward the central sphere. Kaelen grabbed a femur from the mosaic—it resisted, screaming with phantom pain—and shoved it between two of the obsidian rings. The rings ground to a halt with a shriek of tortured stone. Given the confusion around updates (the game is
The updraft stuttered.
Kor-Veth roared, its form flickering. The amber light in the floor dimmed. The chamber grew cold.
Mira grabbed Kaelen's hand. "Now!"
They leaped for the vertical shaft. The dying updraft caught them, lifting them not with heat but with the last gasp of a wounded leviathan. They shot upward through darkness, scraping against carved walls, past ancient murals of the First Builder sealing the warden for the first time.
They burst from the shaft onto a hillside overlooking the ocean. Dawn. Real dawn, not the perpetual twilight of the jungle. The sun rose gold and indifferent over the waves.
Behind them, the ground shuddered once. Then silence.
Kaelen rolled onto his back, coughing up dust and blood. Mira lay beside him, staring at the sky.
"The island isn't finished with us," she said quietly. "We just bought time."
Kaelen turned his head. On the horizon, he saw smoke rising from a part of the jungle they had never explored. And in the smoke, a shape. Not Kor-Veth. Something larger. Something older.
The chapter closed with a single line from Mira's recovered journal, now partially burned:
"The warden was only the first lock. The castaway who reads this: pray you never find the second."
End of Chapter 12.
Next time in Chapter 13: The Smoke Pyramids – Kaelen and Mira meet another survivor who has been on the island for thirty years. But he is not human anymore.
The Chapter 12 update for Island Castaway: Lost World introduces the Great Temple, advanced metallurgy, and new farming options, marking a critical turning point in the survival saga. The update also includes significant performance optimizations, inventory UI improvements, and fixes for previous bugs. You can find more details in the official game update notes.
The user’s request likely refers to the The Island Castaway: Lost World
game series. Notably, the official game was discontinued by developers after Chapter 11. Consequently, "Chapter 12" primarily exists as fan-made content
or fanfiction attempts to provide a satisfying conclusion to the story.
The following essay draft explores the themes and narrative directions of the Chapter 12 fan-fiction projects, focusing on the resolution of the main characters' survival and the mystery of the "Lost World."
Bridging the Unknown: The Narrative Significance of Chapter 12 Island Castaway: Lost World
saga remains one of the most compelling survival simulations in mobile gaming, yet it is famously defined by its abrupt ending. After eleven chapters of resource management, ritualistic mystery, and interpersonal drama, the official story ceased, leaving players on a literal and metaphorical cliffhanger. In the absence of an official update, fan-authored "Chapter 12" narratives have emerged not just as content extensions, but as essential thematic closures that emphasize human ingenuity and community resilience. Resourcefulness as Resolution
In popular fan-fiction continuations of the story, Chapter 12 begins with the immediate aftermath of Amelia’s illness and the logistical nightmare of severed island connections. The central conflict shifts from mere survival to reconstruction
. Characters like Tom and Machk must decide between repairing broken bridges or clearing treacherous railroad tunnels to reach the northeast island. This choice reflects a core theme of the series: the tension between restoring the old world’s technology and adapting to the island’s natural primitive state. The mechanical labor of gathering lianas, boards, and clay becomes a meditative act of reclaiming agency over a hostile environment. The Healing Power of the Island
The narrative weight of Chapter 12 often hinges on the survival of Amelia. Fan scripts depict the castaways utilizing the island’s unique flora—such as watermelons, oranges, and coconuts—to craft medicinal fruit cocktails. This transformation of the island from a place of danger into a source of healing is pivotal. It suggests that the "Lost World" is not merely a prison, but a sanctuary that rewards those who learn its secrets. The inclusion of mystical elements, like deciphering cryptic markings and confronting "crab monsters," adds a layer of mythological depth that the official game hinted at but never fully realized. Community and Legacy
Perhaps most importantly, Chapter 12 addresses the "unjustly omitted" characters and unresolved relationships. By bringing together the disparate groups—John at the eel farm, Olof in the jungle, and the ill at the beach—the fan-made conclusions emphasize that survival is a collective endeavor. The "Lost World" is ultimately found not through a map, but through the bonds formed between the castaways.
While the official developers may have moved on, the persistent creation of "Update 12" content by the player community serves as a testament to the story’s enduring impact. It proves that a narrative’s ending is not always written by its creators, but by those who lived within its world. gameplay mechanics (like the clay pit and liana farming) or the character interactions between Tom and the other survivors?

Chapter 12: The Ancient Ruins
As I emerged from the dense jungle, I stumbled upon a clearing that revealed a breathtaking sight. Before me lay the remnants of an ancient civilization, hidden away for centuries. The crumbling structures, overgrown with vines and moss, seemed to whisper secrets of a long-lost world.
I approached cautiously, my senses on high alert. The air was thick with the scent of damp earth and decaying vegetation. I had been on this island for weeks, but nothing could have prepared me for this. The ruins stretched out before me, a sprawling complex of temples, plazas, and what appeared to be a palace.
As I ventured deeper into the ruins, I noticed strange symbols etched into the stone. They seemed to dance across the walls, telling a story of a people long gone. I followed the symbols, my curiosity piqued, and discovered a large stone door adorned with intricate carvings.
The door was covered in dust and vines, and it looked like it hadn't been opened in centuries. I pushed and pulled, but it wouldn't budge. Just as I was about to give up, I noticed a small inscription on the wall nearby. It read: "For those who seek the truth, look to the sun."
I pondered the message, wondering what it could mean. As I looked up, I noticed that the sun was directly overhead, casting a beam of light onto the stone door. I followed the beam, and to my surprise, a small indentation on the wall lit up. I pressed it, and the stone door creaked open.
Beyond the door lay a chamber filled with ancient artifacts. I marveled at the treasures before me: golden idols, precious jewels, and mysterious devices that seemed to defy explanation. As I explored the chamber, I stumbled upon a series of ancient scrolls.
Unrolling one of the scrolls, I discovered a map of the island, detailing a path that led to the heart of the lost world. I felt a surge of excitement and trepidation. What secrets lay hidden at the heart of this mysterious place?
As I continued to explore the ruins, I began to piece together the story of the civilization that once thrived here. They were a people who possessed knowledge and wisdom beyond my wildest dreams. Their legacy lived on in the ancient structures, artifacts, and symbols that surrounded me.
But I knew I couldn't linger here forever. The sun was setting, casting long shadows across the ruins. I reluctantly left the chamber, determined to uncover the secrets of the lost world.
To be continued...

Official development of The Island Castaway: Lost World concluded at Chapter 11, with no official update for Chapter 12 released as of 2026, according to G5 Entertainment.

The air in the hidden valley of the "Lost World" didn't just feel warmer; it felt older. As the group crested the final ridge of the volcanic basin in Chapter 12, the familiar salt-spray scent of the island was replaced by the heavy, cloying aroma of prehistoric ferns and damp earth. The Descent
The "Upd" (Update) to the journey begins with a treacherous climb. Unlike the previous jungles, the flora here is bioluminescent. Kai leads the way, his machete notched and dull, hacking through vines that bleed a thick, neon-blue sap. They aren't just looking for a way home anymore—they’re looking for the source of the radio signal that shouldn’t exist in a land forgotten by time. The Discovery
In the center of the valley lies the "Chrome Monolith," a jagged piece of modern tech wedged into the ribs of a long-dead titan. As the castaways approach, they realize the signal isn't a distress call; it’s a broadcast.
The Twist: The "Lost World" isn't a natural evolution. They find rows of stasis pods, some shattered, some still humming with a faint, rhythmic amber glow.
The Conflict: Just as Sarah deciphers the console logs—revealing the island was a "biological lifeboat" for a civilization that fled the mainland centuries ago—the ground tremors. It’s not an earthquake. The Guardians of the valley, massive reptilian shadows with eyes that reflect the bioluminescent flora, have picked up their scent. The Cliffhanger
The chapter closes with the group backed against the Monolith. The radio crackles to life, but it’s not a human voice. It’s a series of rhythmic, melodic clicks that match the blinking lights on the stasis pods. One of the pods begins to hiss, the seal breaking from the inside.
They came here to escape the island, but they’ve just woken up its owners.
Should the next part focus on a stealthy escape from the predators, or should we see who (or what) steps out of the opening stasis pod?
The official development of The Island Castaway: Lost World was halted by the developer, G5 Entertainment, after Chapter 11. Despite in-game messages suggesting more chapters were "coming soon" as far back as 2015, no official Chapter 12 update has been released to date. 🏝️ Official Game Status
