Meccha Chameleon Join Code: Find a Friend's Room

What changed in update 4.1.0

The developer's 4.1.0 announcement says the older server browser was replaced by a search for a five-character alphanumeric join code. The code can be verified inside the game. The same announcement says rooms already in progress are hidden from public search by default, with an option to change that behavior. A missing public listing therefore does not prove that a private invitation or the game itself is broken.

Treat the code as a temporary pointer to the host's current room, not as a permanent friend ID. Ask the host to read it from the active room screen after the room is created. A code copied from a previous session, a screenshot of an earlier lobby, or a character confused with a similar-looking letter can send you down the wrong troubleshooting path. Do not publish a private room code in a public chat if you want to control who joins.

The shortest host-and-guest check

First, the host creates or opens the intended room and checks whether it is private. Next, the host reads the current five-character code aloud or sends it directly to the invited players. The guest searches using the in-game code entry and compares the displayed room information with the host's description before joining. That last comparison matters when several friends are trying different rooms at once.

If the result is absent, have the host confirm that the room is still open, has room for another player, and is in the expected state. The official store recommends two to ten players, while actual capacity depends on the host's network and current game settings. A full or already running session is a different problem from an invalid code. Write down which step failed rather than repeatedly refreshing without changing anything.

Separate public search from an invited join

A public room is meant to be discoverable; the Steam store notes that a server that is not private may be joined by anyone. A friend-only plan should start with the host's privacy setting, followed by a direct code exchange. Searching the public list and failing to see an in-progress room is consistent with the 4.1.0 default. Ask the host whether the current room should appear publicly before treating this as a fault.

For a stream or a large group, tell everyone when the host is opening the room and when the code will be shared. Decide whether late arrivals should be allowed after a round begins, then set the room accordingly. A code appearing on a stream overlay or screenshot is effectively a public invitation. If an unexpected player appears, review room privacy and create a new session when necessary; do not assume that a hidden listing makes a leaked code harmless.

Use an ordered troubleshooting ladder

Check the five characters against the host's current in-game display. Then check room privacy, available places, and whether the session is waiting or already playing. The 4.1.0 notes also say that selecting a region tag became required, so confirm both players are looking in the intended region and that the host has set it. If friends use different platforms, verify the current cross-play option and read the separate PC and Switch 2 guide.

Only after those visible checks should you try ordinary connection steps: confirm the game is updated on both devices, restart the game once, and retry with a fresh room. These steps are diagnostic suggestions, not a claim that a particular error code has one known cause. Do not disable security software, download a separate joining tool, or follow a third-party executable link. If the problem persists, record the game version, platform, room state, and exact on-screen message for the official support channel.

Make the first match prove the connection

When everyone reaches the lobby, run a short round on an official map before adding community maps or unusual settings. This keeps map compatibility out of the first connection test. Assign one person to host, one to verify the guest view, and one to note whether the round begins normally. If the official map works but a Workshop map fails, move to the map guide rather than changing the room code repeatedly.

A successful join is not the entire play experience. Check whether all players see the same lobby, whether the host can start, and whether the session survives the first transition into a round. Use the checklist below to record each visible step before the next round. Keeping the connection test small gives your group a clear answer and protects the first ten minutes from random setting changes.

Keep the conclusion testable

The useful result is an identified failed step: code, room state, privacy, region, capacity, platform option, or map. Changing one variable at a time is faster than guessing at every network setting. Recheck the developer's current Steam announcement if the lobby interface changes again.
