MEGABONK · MAKE YOUR NEXT CHOICE
Multiplayer Guide in Megabonk
Use BonkWithFriends to host or join a Megabonk co-op game through Steam, with a short fix for missing menus and failed invites.
PLAY TOGETHER
Start a lobby for your friends
These steps use the BonkWithFriends co-op mod and Steam invites.
Make sure everyone has the same Megabonk build and exact BonkWithFriends version in a matching mod profile.
Launch the modded game and choose Multiplayer → Create Multiplayer Game from the main menu.
Send friends a Steam invite after the lobby opens. Ask each guest to join from the invite or your Steam friends entry.
