Once Human 3.1.2 Adds Nailoong Event, First-Person Tweaks, and Custom Server Reviews

Posted on by

Once Human is getting its Version 3.1.2 update on November 4, 2026, with maintenance starting at 3:00 PM PT and expected to run for about two hours. After the servers come back, players will receive Starchrom x1,000, Mitsuko’s Mark x100, one Stardust Secret Crate S15 Epic, Colorful Badge x30, and five Transformation Cookie: Nailoong items.

The headline addition is the Nailoong crossover, which runs from November 5 to November 25 server time. Players can type “NAILOONG” in World chat during the event to get a transformation cookie, turn into Nailoong, use the limited Tummy Battle skill in the wilderness, and pick up event items like the Nailoong Disco Light and photo frame. Those items stop working after the event ends.

  • First-person play has been cleaned up with a reworked roll animation, smoother ladder climbing, better low-obstacle climbing, and a camera switch option for left-side weapon positioning.
  • Territory building now supports batch replacement and removal for material skins and facility cosmetics, plus better holographic construction tools for moving houses and placing layouts.
  • More fashion sets and parts now support custom dye options through the cosmetics interface.
  • Isles of Abyss gets new Water Territory ship-building facilities, including a Straight Ladder and Rolling Shutter Door.
  • Custom Server players and Official Server players can now add each other as friends, send private messages, and join group chats.
  • Custom Servers also now have a comment feature, available to players who have spent at least 10 minutes on a server.

The update also touches combat and exploration in Isles of Abyss. Voyager HP in the wilderness has been adjusted, with level 60 Voyagers getting the biggest changes, and boats can still be steered even when they weigh more than 10,000 kg. The patch also increases the chance to get level 6 Ship Cannons in level 60-plus land calamity zones.

On the shop side, the Party Boing! Lightforge Loot Crate and the Awoo’s Adventure Combo Crate arrive after the November 4 update, both tied to the Nailoong crossover. A separate Poem of Binding repeat-draw blind box is scheduled for November 11 PT.

There are also smaller fixes across construction, dungeons, and combat, including a fix for Naval Mines not being craftable and an issue where Rosetta Elite enemies in Securement Silo – ALPHA failed to drop Access Cards when killed by lasers. The next Once Human update is currently scheduled for November 18 at 3:00 PM PT.
