Once Human goes down for maintenance on November 4, 2026 at 3:00 PM (PT) to install version 3.1.2. The downtime should last about two hours. Once servers are back, every player can claim 1,000 Starchrom, 100 Mitsuko’s Mark, a Stardust Secret Crate S15 (Epic), 30 Colorful Badges and five Nailoong Transformation Cookies.
Nailoong crossover, November 5 to 25
The headline of the patch is a crossover with Nailoong, the round yellow dragon character. From November 5 to November 25 (server time), typing “NAILOONG” in World chat gets you a cookie that turns your character into the creature. In that form you can use a belly-bump skill called Tummy Battle in the wilderness. There’s also a Disco Light from the daily check-in that starts a dance party nearby, and a themed photo frame. None of these items will work after the event ends.
Each account also gets a Nailoong Egg to hatch together with friends. Daily tasks and friend invites give you hatch attempts, and progress is shared across all characters on the account. Along the way you earn an avatar, a namecard and a namecard theme. A full hatch unlocks Carpenter Nailoong, a Logging Beaver Deviation skin. A Nailoong Wheel spin event and a range of themed cosmetics in the shop round out the crossover.
Combat, building and balance
First-person play gets a broad overhaul:
- A new roll animation built for first-person view
- Smooth, continuous ladder climbing instead of fixed steps
- Climbing over low obstacles from any direction
- A Camera Switch option that moves your weapon to the left side of the screen
Builders can now swap or remove material skins across an entire connected building in one go. The same works for all facilities of one type inside a building. Holographic construction also improves: whole houses can be moved with snap points, the material cost of a selected structure is shown, and floating builds get an automatic support path. Ships gain a Straight Ladder you can climb from the water and Rolling Shutter Doors for dividing interior space. Water Territory facility limits are now separate from regular Territory limits.
On the Isles of Abyss, Voyager HP has been rebalanced around actual Ship Cannon damage so fights end sooner, with Lv. 60 Voyagers seeing the largest change. Lv. 6 Ship Cannons drop much more often in Lv. 60+ land calamity zones. Cannonballs, Mist of Deceit Wicks and Mist Core cannonballs also hit the Calamity Tower harder. A bug that stopped the Mist ammo multipliers from applying to Voyagers and buildings has been fixed too, and Naval Mines can finally be crafted through the Tech system.
Other changes include:
- Custom Dye support for 24 fashion sets and 25 fashion parts
- Up to two copies of certain Fashion Traits can be equipped at once
- Beastmaster Quick Commands
- Sheep that no longer scatter as soon as you approach
- Xbox One controller support
- Fewer anti-cheat false positives when characters get stuck in terrain
Custom Servers get several additions. Their players can now friend and message people on Official Servers, and hosts can set up entry and login gift packs. A new review system lets anyone with at least 10 minutes on a server rate it. These servers also gain the Heart of the Sunken dungeon and the deployable Deviations Duet and Chaos Rebecca.
The next update is set for November 18, 2026 at 3:00 PM (PT). It will introduce a new mode called the Visional Wheel, which the developers will explain in upcoming Dev Blogs.
