In "Monster Hunter: Wilderness", players need to use code ID if they want to enter a friend's private hall. However, many players are not sure how to use the hall code. In fact, if you want to use the code ID, you can enter the title screen main menu → Start the game → Select your Hunter → Hall Search → Hall ID Search.
How to use Monster Hunter's Wilderness Hall Code ID
Your friend will use the Hall ID code and join your hall: Go to the title screen main menu → Start the game → Select your Hunter → Hall Search → Hall ID Search.
Or, in the game and base camp, your friends can talk to Alma → go to the third tab to change the lobby menu → lobby search → lobby ID search.
If your friends enter the correct code, they will start loading into the lobby. Congratulations, now you should all be in the same private hall! This is the hardest part. You can view the lobby member list: Start menu → Communication (Page 4) → Member list, and then select Page 2 to view lobby members.
