Fast join order
Have every player close the game, let Steam finish updates, relaunch Steam, then start Meccha Chameleon. The host should create a fresh room only after everyone is on the same build.

Quick Answer
To join friends in Meccha Chameleon, update Steam first, match the same game build, use a direct Steam invite as the control test, then recreate the room if public discovery fails.

Use Steam invite as the control
A direct Steam invite is the cleanest test. If the invite works but public discovery does not, the issue is probably room browser visibility rather than friend connectivity.
When to recreate the room
After a failed join, do not keep reusing the same lobby forever. Recreate the room, send a new invite, and confirm every player sees the same version after launch-week hotfixes.
What to report
If joins still fail, report host region, lobby type, player count, game build, Steam invite behavior, and whether VPN or proxy routing is enabled.
Fix checklist
Problem: Players cannot join each other reliably through Steam or public room search.
- Use Steam invite first, then public room search as a fallback.
- Make sure every player is on the same build after hotfixes such as 1.0.x, 1.1.0, or 1.1.1.
- If invite opens the game but not the room, recreate the lobby and invite after the room is fully loaded.
- If public search fails, match region/network conditions by disabling VPN and restarting Steam.
- For streamers, create the room early and test with one moderator before sharing room details publicly.
- Restart Steam and confirm both players are on the same game build.
- Use Steam invite first, then test public room discovery second.
- Disable VPN or region routing if public rooms fail to refresh.
- Verify game files after any version mismatch or connection loop.
- Check Steam Community announcements before assuming a local issue.

Frequently Asked Questions
Why can I not join my friend? +
The most common causes are different game builds, Steam invite state, room visibility, VPN routing, or a lobby that needs to be recreated after an update.
Should we use public rooms or Steam invites? +
Use Steam invites first because they separate friend-join problems from the public room browser.
What should the host do first? +
Restart Steam, confirm downloads are complete, create a fresh room, then send a new invite after all players relaunch.
Does lobby size matter? +
Yes. Meccha Chameleon is built around 2-10 player rooms, so private-room testing is easier with a small group before filling the lobby.
