Once Human Isles of Abyss RaidZone is the PvP ocean scenario arriving with the October 21 Pacific-time update. Instead of sailing in the regular Isles of Abyss PvE servers, everyone on a RaidZone server shares one contested map where rival ships can attack each other.
The risk isn’t just losing a fight. A sunk ship loses the supplies stored aboard, and getting it back into the water depends on whether you’ve saved its blueprint. Here is how to choose the PvP mode, which servers are available and what to do before setting sail.
How to join Once Human Isles of Abyss RaidZone
To enter Once Human Isles of Abyss RaidZone, go to the character sign-in screen and switch to RaidZone using the option in the upper-left corner. Then choose the ocean server called RaidZone_Isles_Abyss-A0001 for your region.
That is different from ordinary Isles of Abyss. Its PvE servers appear through scenario sign-up and use the Isles_Abyss-X0001 naming format. If you only want cooperative ocean survival, stay with the PvE scenario rather than changing your game mode at sign-in.
Once Human Isles of Abyss RaidZone server options
For the North America and Europe region grouping, NC lists the regular RaidZone_Isles_Abyss-A0001 server and [Console] RaidZone_Isles_Abyss-A0001. The second is console-exclusive. NC’s official server schedule covers other regions.
The initial schedule lists one standard ocean RaidZone server for South America, Japan, Korea, Southeast Asia and the Hong Kong, Macau and Taiwan grouping. The developer plans a biweekly server reopening cycle and may add more servers if needed.
RaidZone has no separate worlds. Unlike PvE’s twelve worlds per server, players on the same RaidZone server share one ocean map. Make sure you’re selecting the mode you want.
| Mode | Initial NA/EU servers | Worlds | Purpose |
|---|---|---|---|
| Isles of Abyss PvE | 4 | 12 per server | Cooperative ocean survival |
| Isles of Abyss: RaidZone | Standard plus console-exclusive server | No world divisions | Ocean PvP |
How RaidZone PvP changes ocean exploration
Once Human Isles of Abyss RaidZone has the same broad island and ocean landscape as Isles of Abyss, but fewer supplies on the water. NC expects players to run into competitors more often while exploring and gathering resources.
Build enough basic equipment and provisions to start moving safely, then decide how much you’re willing to risk on a contested trip. You may need to avoid another ship, fight over a resource or head home before your cargo becomes too valuable to lose.
Because Once Human Isles of Abyss RaidZone brings everyone together without world divisions, choosing a route is part of the PvP challenge. A quiet gathering trip can turn into a battle if another crew wants the same supplies.
What happens when your warship sinks?
Your warship doubles as a mobile territory. It has its own total HP, and attacks in naval combat reduce that HP. When it reaches zero, the ship sinks immediately.
Supplies stored on a sunken ship aren’t refunded. That’s the biggest risk of carrying a full hold into PvP. You might recover by rebuilding the vessel, but the notice doesn’t promise to return the cargo you lost when it went down.
Before taking a loaded ship into Once Human Isles of Abyss RaidZone, decide what you actually need on board. Keeping everything you own at sea makes one bad encounter much more expensive than it needs to be.
Save your ship blueprint before a fight
Once you’ve expanded or upgraded your warship, visit the Anchor and save its ship blueprint. NC says saving a blueprint both records your construction and increases the ship’s maximum HP.
If the ship sinks, you can summon it again using a previously saved blueprint. Without one, you can only summon its initial design. Saving your ship blueprint does not restore the cargo lost in the sinking. Your saved design and the supplies carried aboard are two different things.
Saving the blueprint is worth doing before serious fights, not after. The Once Human ship-building guide covers the wider construction system, while Once Human Isles of Abyss RaidZone adds the risk of losing your cargo in PvP.
RaidZone or PvE: which should you choose?
Pick regular Isles of Abyss PvE if you want island survival, shipbuilding and the Sunken Lord without fighting other players. Those servers have twelve worlds each and use the standard scenario-selection sign-up process.
Choose Once Human Isles of Abyss RaidZone when you’re specifically looking for ship combat against other players, scarce ocean supplies and the shared PvP map. RaidZone has its own entry switch and server schedule; it isn’t a PvP toggle inside a PvE world.
The Isles of Abyss joining guide covers PvE registration, and our launch guide lists the platform download sizes. Maintenance starts at 4 PM Pacific on October 21, equivalent to midnight BST on October 22, and is expected to take around three hours.
