Big Walk Public Lobbies: Server Browser Mod & Join Codes

Updated 2026-09-03 · Steam Big Walk

Big Walk has no built-in public lobby list. The vanilla flow is private: one player hosts, the game hands them a join code, and everyone else types that code in. Since patch 1.4.9 a session password is also mandatory on every new game, which killed the older habit of trading codes on the forums. The community answer is a mod, BigWalk_Public_Lobbies by khalil, which tags rooms whose hosts opt in and shows them, password included, in a browser attached to the main menu. There is also a mod-free route: a fan-made code board advertised in a Steam guide.

Nothing on this page is an official House House feature. The mod is community software and the developers have never mentioned modding in a patch note.

How Big Walk lobbies work without any mod

Big Walk is an online co-op game for 2 to 12 players with cross-platform support, per the community Fandom wiki, and the Steam store lists it under Online Co-op and Cross-Platform Multiplayer. Matchmaking is invite-style rather than browsable.

Element	What the sources say
Join code	Players report the host receives a 6-digit code to pass around; one Steam guide's whole fix for "connection failed" is to create the world, copy the code, then press play before sending it
Session password	Required on every new game since version 1.4.9, per the developer patch notes published 21 August 2026
Public room list	Not present in the base game. The Steam guide author who built a code board states plainly that the game ships without a server browser
Player range	2 to 12 players with crossplay, per Fandom; more on multiplayer
Connection errors	Patch 1.4.10 added more specific network error messages and warnings on the host and join menus

The join-code detail and the hosting order are player-reported from Steam Community guides, not documented by House House.

BigWalk_Public_Lobbies at a glance

Field	Value
Package	khalil/BigWalk_Public_Lobbies
Version	1.5.0
Downloads	2,828
Created / updated	6 August 2026 / 21 August 2026
Categories	Mods, Misc
Dependency	BepInEx-BepInExPack_IL2CPP-6.0.755

That dependency matters: Big Walk is an IL2CPP Unity title, so the IL2CPP pack is the correct one and the Mono pack will not work. A mod manager such as r2modman or Gale pulls it in for you. Full install steps live on mods.

What the browser actually does

Everything below is the author's own README description rather than something this wiki has verified.

A Public Lobbies button is added to the main menu. Opening it fires a single targeted search for rooms carrying the mod's tag, with a cap of 200 results per round. Every refresh is a fresh snapshot with no caching.
Each card's first line shows the world name and the room password. The README distinguishes three states: a real password, an explicitly empty one shown as none, and unavailable.
Hosting with the room tag switched on publishes both the tag and the current password as public lobby attributes. Change the password in game and the listing updates itself; clear it and the attribute is removed, so a stale password does not linger.
Joining is not automated. The mod calls the game's own connect routine, so you get the normal connecting screen, the normal password prompt and the normal error menu. Nothing is auto-filled or bypassed.
A "my language only" filter matches rooms by the script of the world or host name, grouping Chinese, Japanese, Korean and Russian separately and Latin-alphabet languages together. The interface itself is translated into 15 languages and follows the game language live.
Cards show live player counts, and full rooms drop off the list automatically.
Version 1.5.0 fixed a bug the author attributes to leaked search handles in older versions, which players reported as being unable to join any room at all. The fix recycles handles and fires exactly one search per refresh.

Rooms tagged by versions before 1.5.0 carry no password attribute and show as unavailable, and so do passwords longer than 64 bytes, which the mod refuses to publish rather than truncate.

Configuration

The config file is BepInEx/config/BigWalkPublicLobbies.cfg, and the README says every setting hot-reloads while the game runs.

Setting	Default	Effect
`[Search] TaggedRounds`	1	Search rounds per refresh, maximum 10. One round already returns everything; 0 sends no request at all and leaves the list empty
`[Mod] EnableRoomTag`	true	Tags rooms you host and publishes their password. Turning it off only affects future rooms
`[Dev] DevMode`	false	F5 opens the panel in any scene, useful for checking your own room appears
`[Debug] Verbose`	false	Detailed logging, which the author states never records password values

If the panel never appears or the game will not start, work through mods not working before blaming the mod itself.

Safety: the password is public on purpose

This is the part worth reading twice. The README is explicit that the published password is a public lobby attribute, readable by anyone who can search for that lobby. That is the whole point of the feature, but it means:

Never reuse a password you use anywhere else as your session password while the room tag is on.
Turning EnableRoomTag off does not untag a room you already started. Host a new one to clear it.
Opting in means strangers can join a walk. Big Walk runs on proximity voice, so a public room is a voice room; see voice mods for per-player volume control if someone is being loud.
The mod does not touch the game's password check, so the vanilla protection still applies to everyone.

Thunderstore's Big Walk community also hosts mods that let one player disrupt a lobby. This wiki does not write guides for those. The curated list on best mods leaves them out too.

The no-mod route: the Steam code board

A Steam Community guide titled "Big Walk Server Browser" points to a free, fan-made website where hosts post their join code alongside region, language, group size, story progress and whether mics are expected. According to the guide author, posts expire after 24 hours unless bumped, so dead codes fall off; browsing and copying codes needs no account, while posting or commenting requires a sign-in. It is fan-made and not affiliated with House House. We link the guide rather than the site so you can read the author's own terms first.

This route works on console and on unmodded PC installs, which the mod route does not.

What patches can break

Lobby handling is exactly the area House House keeps touching, so expect the mod to need updates. Patch 1.4.10 on 21 August 2026 improved network stability and added connection warnings to the host and join menus. Patch 1.5.1 on 28 August 2026 reworded the host menu password prompt, made the connect-time prompt clear itself after a failed attempt, and split the network warning into separate slow and unstable messages. A full list is on patch notes.

Sources and last check

Checked 3 September 2026. Mod version 1.5.0, its 2,828 downloads, the 21 August 2026 update date, the BepInExPack_IL2CPP 6.0.755 dependency, every feature, config key and privacy note come from the package page and README for khalil/BigWalk_Public_Lobbies on Thunderstore, and are the author's claims rather than results this wiki has tested. The mandatory session password in 1.4.9, the 1.4.10 network changes and the 1.5.1 password-prompt changes come from the official House House Steam announcements dated 21 August 2026 and 28 August 2026. The 2 to 12 player range and crossplay support come from the community Fandom page for Big Walk. The 6-digit join code, the hosting order that reportedly fixes connection failures, the absence of a built-in server browser and everything about the fan-made code board are player-reported from Steam Community guides, in particular the "Big Walk Server Browser" guide, and are not confirmed by the developers.
