Is Multiplayer Available?
Available for Co-Op Play

You can team up with friends in Co-Op Dungeon modes, making it easier to farm materials and clear dungeons more efficiently.

Although Co-op Mode exists, the game is primarily single-player. You won’t be able to play together with friends or other players unless you’re entering a dungeon.
Coop Area Available

There are Coop Areas on the map where you may encounter other players. Entering the area will automatically enable coop mode, but it can be turned off from the settings. It is unlocked by completing the Main Quest "On a Gentle Breeze".
What Can You Do?
Coop Area's only function is to increase the liveliness of the game, and other than seeing other players, there is no function player can perform.
How To Unlock Multiplayer Mode

To unlock Co-Op Mode, you’ll need to complete Story Chapter 1: “Black Iron and White Flower.” Once cleared, you’ll be able to take on dungeon quests together with your friends.
