Multiplayer appears at the hideout radio after the host clears the first three raids.
To start Splatoon Raiders multiplayer, the host must complete the first three raids on Erpp Island, return to the hideout ship, use the radio, and choose local wireless or online play. The session supports two to four players.
Exact setup
- On the host save, finish all three opening Erpp Island raids.
- Return to the hideout ship.
- Interact with the radio.
- Choose Local Wireless or Online Play.
- Create the room and have the other players join through the matching connection method.
If the radio does not offer multiplayer, recheck the host's raid completion rather than the guest's progress. If the option appears but nobody can join, the unlock is working and the problem has moved to network, account, subscription, software-version, or local-wireless setup.
Keep all systems on the current game update. For online play, confirm the participating Nintendo Accounts and required service access. For local wireless, keep the systems nearby and make sure every player selects the same local connection flow rather than mixing it with online.
Nintendo says one member of Deep Cut is controlled by the game in the group. This guide does not promise unrestricted character selection or split-screen play; the documented modes are local wireless and online across supported systems.
Quick diagnosis
Use the point of failure to choose the next check. No radio option means the host's opening raid sequence is incomplete. A visible room that cannot be joined points to connection or account conditions. A session that disconnects after starting is not an unlock problem; update all copies, restart the networking equipment if appropriate, and consult Nintendo's current network support. This distinction prevents erasing a valid save or repeating the first raids when progression is already correct.
