Introduction
This update not only brings the all-new AZ3 Nuclear Plant map, dynamic radiation mechanics, and new Operator 'Liquid Nitrogen,' it also ignited an ARG (Alternate Reality Game) easter egg event spanning two seasons and mobilizing tens of thousands of players. From hidden clues in the S9 season PV, to the QR code easter egg website in the S10 nuclear plant trailer, to the ultimate challenge of the 36-digit code door and the completely invisible air wall maze — this series of designs has been hailed by the community as 'the most brilliant ARG narrative in FPS history.'
This article will fully retrace the entire ARG decryption process, detail how the 36-digit code door and air wall maze were conquered, and cover the AZ3 Nuclear Plant map's radiation mechanics, Protocol Crate locations, and practical survival strategies. Whether you're a puzzle enthusiast wanting to explore the mystery firsthand, or a combat player looking to get rich safely on the new map — this guide is worth bookmarking.
1. ARG Full Decryption Journey: From S9 PV to the Ultimate 36-Digit Code Door Breakthrough
This ARG's narrative spans across both S9 and S10 seasons, and the intricacy of its design is nothing short of astonishing. [CONFIRMED] The starting point of the entire decryption chain was a hidden visual clue in the S9 season PV — the first hint of the nuclear plant accident, which almost no players noticed at the time. After the S10 nuclear plant PV was released, keen-eyed players discovered a scannable QR code in the scene behind the bald boss. Scanning it led to an encrypted investigation report website designed in the style of Havk Corporation's internal system.
This encrypted report required a specific password to unlock, and the password — [CONFIRMED] — was hidden within the decryption terminals inside the AZ3 Nuclear Plant map. The decryption process was interlinked and self-contained: players needed to traverse 8 key terminals across the entire map, completing either 'wire sorting' or 'memory' mini-games to obtain password fragments.
Key Decryption Nodes:
i. S9 PV Hidden Clue: Extracted by early puzzle-solving players, revealing a nuclear plant map hint — foreshadowing the S10 ARG.
ii. S10 PV QR Code: Scanned to access the Havk encrypted investigation report website, with UI design that enhanced narrative immersion.
iii. 8 Decryption Terminals: Scattered across the map, each requiring completion of a mini-game. All fragments combined to assemble the 36-digit code.
iv. 36-Digit Code Door: The first climax of the entire ARG — just when all decoders thought this was the end, the real challenge was only beginning.
2. Air Wall Maze: A Miracle of Mass Collaboration by Tens of Thousands of Players
After the 36-digit code was successfully entered, the treasure door all decoders had been expecting did not appear — instead, what awaited was a massive labyrinth built entirely from invisible air walls. No visible walls, no floor markings, no navigation hints whatsoever. [CONFIRMED] This design instantly ignited the player community, becoming the most-discussed topic of S10 season.
The process of conquering this maze may well be the most epic player collaboration event since Delta Force launched. With the air walls being completely invisible, players invented a series of brilliantly creative collaboration methods:
i. Bullet Marking Method: Pioneers fired at air walls, and the bullet holes became natural 'dead end' markers, saving those who followed enormous trial-and-error time.
ii. Hand-Drawn Mapping: Hardcore players recorded their movement trajectories step by step, hand-drawing the air wall layouts into maps shared with the community.
iii. Dedicated Path Recorders: Some players volunteered as 'path scribes,' organizing every correct route segment into text guides posted for community reference.
iv. Collision Relay: Multiple teams matched into the same session simultaneously, dividing exploration of different maze zones and pooling discoveries together — efficiency increased exponentially.
After relentless efforts by tens of thousands of players, the maze was fully conquered within days of the live server launch. At the maze's end, [CONFIRMED] lay a fallen Havk employee's body, a tightly shut door, and an employee ID card. The employee number on that card was precisely the password to unlock the final encrypted investigation report.
3. Investigation Report & Hidden Ending: 'World Without Nuclear'
After unlocking the investigation report with the employee ID number, players gain access to two critical documents:
i. Nuclear Plant Accident Investigation Report: Details the full story behind the AZ3 Nuclear Plant accident, revealing numerous dark secrets of Havk Corporation's nuclear facility management — with details forming a clever echo of S9 foreshadowing.
ii. Employee Personal Diary: The account number '3707006600874797' in the diary corresponds to a real easter egg user on Bilibili (Chinese video platform). Following this account reveals more ARG-related content. The 'red eyes' imagery in the diary has sparked speculation — [UNCONFIRMED] players suspect it may hint at a future biohazard mode, though this has not been officially confirmed.
The true climax of this ARG is the hidden 'World Without Nuclear' ending within the map. [CONFIRMED] This is a meta-design homage to Metal Gear Solid V: The Phantom Pain: in a single Nuclear Plant match, if ALL players on the map reach a tacit agreement — at the start of the round, instead of activating any nuclear facility terminals, they choose to suspend their operation — the reactor power will eventually drop to zero, and all players on the map collectively achieve the 'World Without Nuclear' hidden achievement.
[NOTE] This design is nearly identical to The Phantom Pain's hidden trophy requiring the entire server to dismantle nukes together. However, limited by the presence of uncontrollable AI bots and randomly matched players in each match, the probability of triggering this ending in normal gameplay is extremely low. According to estimates by Zhihu (Chinese Q&A platform) players, excluding deliberately organized collusion lobbies, the random trigger probability approaches zero. Players wishing to experience this are advised to organize collusion lobbies through community groups.
Conclusions:
Delta Force S10 'Fission' season's AZ3 Nuclear Plant map not only brings unprecedented tactical depth through radiation mechanics and three-layer vertical structure, but also — through an ARG easter egg spanning two seasons, featuring the 36-digit code door, air wall maze, Havk investigation report, and 'World Without Nuclear' hidden ending — has created a truly collective narrative experience for the player community. From bullet-marked walls to ten-thousand-player collision relays, this easter egg has already become a highlight moment in the history of Chinese FPS game operations.
