MEGABONK · MAKE YOUR NEXT CHOICE
Play Megabonk Co-op
Set up BonkWithFriends for Megabonk, host or join through Steam, and follow the right fix when the multiplayer menu or lobby fails.
✦✦YOUR NEXT STEPS
Get everyone into one lobby
Choose Megabonk in Thunderstore Mod Manager and create a separate profile for your co-op group.
Install BonkWithFriends in that profile. Its package declares BepInExPack IL2CPP as a required dependency.
Have every player launch the same game build and the same mod version from their matching profiles.
The host opens Multiplayer → Create Multiplayer Game. Guests accept the host’s Steam invite or use Join Game from the Steam friends list.
CHECK THE PACKAGE
Match versions first
The author's package listed BonkWithFriends 0.5.5 and BepInExPack IL2CPP 6.0.755 when checked. Compatibility with every Megabonk patch has not been confirmed, so use the package's current notes before starting a long run.

IF JOINING FAILS
Check the whole group
Host and guests need the same game build and exact BonkWithFriends build. The mod author rejects mismatched mod versions. Use the compatibility checklist ↗ to find what differs before trying another invite.
