Once Human's new survival scenario, Isles of the Abyss, is about to begin its pioneer confidential test! This vast, unknown, and adventurous ocean world awaits exploration and feedback from you. We welcome you to sign up and join the test. Below are the specific details:
Available Region: North America
Start Time: June 17, 2026(PT). The specific server opening time will be announced separately.
Duration: Approximately 20 days.
Estimated Recruits: 2,000 players.
Test Type: It will be an online, data-wiping confidential test. Participating Metas do not need to download a new client. They can directly use the current client to experience it. After the test concludes, character data on the server will be deleted. Players who are eligible for the test are required to sign a non-disclosure agreement before the test starts. Unauthorized dissemination of any test-related content is prohibited.
Test Content: This scenario will present players with a brand-new maritime survival challenge. You will need to explore a cluster of scattered islands, gather resources amidst dynamic weather and day-night cycles, build facilities, and confront threats from the environment and mysterious enemies.
This test is the Pioneer Test, aiming to validate the core game mode loop, system stability, and story pacing in the early stages of the scenario. We highly value your feedback, which will be used to fine-tune subsequent versions, bringing a better experience to Metas.
Important Notes:
The test content as at this stage is still under development and does not represent the final quality. As the mobile performance adaptation for the "Isles of the Abyss" Pioneer Server is not yet fully complete, we recommend that all Metas participate in this Pioneer Test using PC for a better experience.
We wish to preserve the freshness of the new scenario content for all players. Therefore, all participants in this Pioneer Test must agree to the non-disclosure agreement. During the test period, dissemination of any game content (including screenshots, video, live streams, etc.) is strictly prohibited. Please refer to the non-disclosure agreement terms for full details. Breaking the non-disclosure agreement will trigger severe actions, including account bans, associated account bans, legal action, and other measures.
Thank you for your understanding and cooperation, Metas. Let us work together to maintain a healthy game ecosystem and create a better gaming experience.

Server Access Instruction:
Once you're eligible for the Pioneer Test, you will be prompted to enter the Pioneer Test server upon logging into the game.

* Note: If you are a mobile player, you will first be guided to the download center to download the current Pioneer Test resource pack. After the download is complete, you can start the experience!
You can also continue playing other scenarios. You can switch back to the Pioneer Test at any time via Mode Switch in the upper left corner.

The core zone and game modes of the scenario will be available for this test. The main content includes:
1. Sea Exploration and Calamity Tower Challenge: After the world opens, Calamity Towers in the sea will be gradually activated as World Progress advances. Once activated, Metas can gather allies, sail to the corresponding sea region, and challenge the Calamity Tower. When each Calamity Tower is defeated for the first time, a rewards mail will be sent to all players on the server, simultaneously triggering additional World Progress advancement, speeding up the entry into the season's Phase II. Furthermore, Calamity Towers will generate new challenge variations as World Progress and Scenario Progress advance.
2. Exploration, Building, and Story: Metas will focus on the island ecosystem, obtaining gear in new ways, collecting new resources, facilities, and tech within the new ocean and underwater environments, and gradually advancing the related story.
3. Day-Night Threat: When night falls, more dangerous enemies will appear on the islands, and the survival challenge will be intensified accordingly.
4. Deviation: Deviations will always appear in the wilderness. Players can directly engage in combat with them and attempt capture.
5. Random Events - Voyagers: These lost ships will cruise along random routes across the major waters of the World. You can choose to destroy them with your ship or board them to scavenge for supplies. Voyagers come in various types. As their size increases and facilities improve, the difficulty will gradually escalate, and rewards from their Loot Crates will scale up accordingly.
6. Survival Events - Haywire Zones:
Haywire Zones are crucial survival events in the isles scenario, bringing unique survival rules and extreme challenges to different island groups.
Four types of Haywire Zones will be available in this Pioneer Test:
Mist of Deceit: The pervasive mist engulfs your vision. The lower your HP, the lower your vision. The key is to wisely use light-based Items to dispel the mist and deal with enemies lurking within.
Skyfire: Meteors falling from the sky have completely transformed the volcanic region. Immense wealth lies hidden within the scorching meteorites.
Time Rain: Anything touched by the Time Rain falls into temporal disorder. Plants and animals grow at unnatural speed, while items and gear wear down rapidly. To survive, make strategic use of the accelerated time to overcome each challenge.
Black Tide: Pollution surges onto the islands in cycles with the Black Tide. Successive Pollution Zones rise here one after another, reshaping the rules of survival.
7. Calamity Zones: After entering Phase II of the scenario, Calamity Zones begin appearing across the world as a result of energy disorder. Each Calamity Zone spawns with a randomized layout and is filled with powerful combat units. Metas must arm themselves, strengthen their ships, and assault the Calamity Zone, destroying the obstacles and threats within, ultimately conquering and clearing it. Clearing Calamity Zones advances server-wide Progress, accelerating the arrival of the world’s final boss, "The Sunken Lord".
8. "The Sunken Lord" Dungeon: An 8-player Legion Dungeon. After Phase II of the scenario begins, "The Sunken Lord" will appear when the Purification Progress reaches 100%.
9. Ship-Controlled Artillery: In this test, you can use the wheel to select one artillery piece to control while sailing, allowing you to defeat enemies at sea while navigating.
