Big Walk Mods: BepInEx IL2CPP Install Guide & Top Mods

Updated 2026-09-03 · Steam Big Walk

Big Walk mods are BepInEx plugins, and the detail that trips most people up is which BepInEx to use. Big Walk is an IL2CPP Unity build, so it needs BepInExPack_IL2CPP (version 6.0.755 on Thunderstore), not the older Mono pack that other Unity games take. The Big Person View README states it flatly: BepInEx 5 will not work in this game. Nearly every package in the community lists BepInEx-BepInExPack_IL2CPP-6.0.755 as its dependency, so the least painful route is to let a manager such as r2modman or Gale install it for you. The Big Walk Thunderstore community holds 67 packages as of 3 September 2026: 59 filed as mods, 2 as tools and 6 as miscellaneous.

None of this is an official feature. House House has not mentioned modding in any Steam announcement we have on file, and the most recent patch is 1.5.1 on 28 August 2026. Treat every mod as community software that can stop loading the moment the game updates.

The three packages that do the work

Package	Version	Downloads	Updated	What it is
BepInExPack_IL2CPP	6.0.755	810,911	2026-03-23	The BepInEx 6 bleeding-edge IL2CPP build for x64 Unity games, repacked with a config that turns the console and fuller logging on by default
r2modman	3.2.19	10,423,468	2026-08-21	Thunderstore mod manager with profiles, profile exports, a config editor and self-updating
GaleModManager	1.22.2	516,063	2026-08-25	A smaller, faster alternative manager built for Thunderstore, with a config editor and profile syncing

BepInEx itself is a general modding framework for Unity: it loads plugin DLLs at launch, patches methods at runtime without editing game files, handles per-mod configuration and resolves dependencies between plugins. The Thunderstore pack is that framework, pre-set for IL2CPP so you do not have to configure anything.

Two safety notes come straight from the managers' own READMEs. The r2modman README warns that third-party sites are posing as official and that only Thunderstore and its GitHub releases are legitimate. The Gale README says the same about itself and names galemodmanager.com specifically as an unofficial site shipping a badly outdated build.

Installing with a mod manager

This is the path the BepInEx pack recommends and the one most Big Walk mod authors point at.

Install a manager. r2modman on Windows is the setup executable inside the Thunderstore download; on Linux the README steers you to the Flatpak (also the route for Steam Deck game mode) or the AppImage, with deb, rpm, pacman and tar.gz builds on GitHub. Gale on Windows is an .msi, and also ships via Scoop and WinGet, with AUR, deb, rpm, Flatpak and AppImage packages on Linux.
Clear the Windows SmartScreen prompt if it appears. Gale's README tells you to choose More Info, then Run Anyway.
Open the manager, pick Big Walk, and make a profile.
Search for a mod and install it. BepInEx arrives on its own as a dependency, so you never download it separately.
Press play inside the manager.

That last step matters, and it is player-reported rather than official. The Big Voice install guide on Steam, written by the mod's own author, says that starting the game from Steam loads vanilla and that you have to use the manager's play button to run modded. r2modman's feature list, by contrast, advertises an install layout that lets you launch through Steam normally. Behaviour differs between managers and profiles, so if a mod is not showing up, use the manager's launch button first and work through mods not working after that.

Manual install: where the files go

You can skip managers entirely. These steps are drawn from the BepInEx pack README and the Big Voice, Big Person View, BigNameTags and SourceMovement READMEs.

Download the BepInExPack_IL2CPP archive and unpack it somewhere that is not the game folder.
Move everything inside the BepInExPack folder into the folder holding Big Walk.exe. If you cannot find it, right-click Big Walk in your Steam library, then Manage, then Browse Local Files. The default is C:\Program Files (x86)\Steam\steamapps\common\Big Walk.
Start the game once and close it. This first run is what creates the BepInEx folder structure, including plugins.
Drop each mod's .dll into BepInEx/plugins/. A few packages want a whole subfolder, for example SourceMovement, whose file is meant to land at Big Walk/BepInEx/plugins/BigWalkSourceMovement/BigWalkSourceMovement.dll.
Launch again. BigNameTags notes that its config file only appears on this second launch.

Path	What lives there
`Big Walk/BepInEx/plugins/`	Mod DLL files, sometimes inside a per-mod folder
`Big Walk/BepInEx/config/`	Per-mod settings, such as `BigVoice.cfg`, `BigWalkPublicLobbies.cfg` or `BigWalk.NoClip.cfg`
`Big Walk/BepInEx/`	The framework itself, created on the first modded launch

If the pack installed correctly, a BepInEx console window opens next to the game, because this build ships with the console switched on.

On Steam Deck, SteamOS and other Linux setups, BepInEx needs a DLL override to load under Proton. Three separate READMEs give the identical launch option: WINEDLLOVERRIDES="winhttp=n,b" %command%.

One inconsistency worth knowing about: at least one popular mod, Big Visuals, still links a BepInEx 5 Mono archive in its manual instructions even though its Thunderstore dependency is the IL2CPP pack. Follow the dependency, not the link.

Does everyone in the lobby need the mod?

There is no single answer, and the only reliable source is each author's own README. Big Walk has no anti-cheat, a point several READMEs in the smolMods family repeat. Here is what the authors actually claim:

Requirement	Examples	What the README says
Only you	Big Voice, Big Visuals, Big Person View	Purely client side; the camera mod says it leaves interaction, audio and other players' view of you alone
Only you, but everyone sees the result	ColorSelf	Colours go through the game's own appearance command, so unmodded players see them too, the same as visiting the salon
Host only	NoClip	Clients cannot switch it on at all, and it turns itself off if you stop hosting
Host for the full effect	BigBack	The author says the host should have it and that client-only behaviour is still being tested
Everyone	BigYeet, BigNameTags	BigYeet says every player in the lobby should install it; BigNameTags is client side but needs both ends for tags to show both ways
Host not required	QuickBelt	Works in multiplayer without the host running it

Achievements are a grey area. Big Walk has 12 Steam achievements, and no developer post in our sources addresses modding at all, so this wiki will not claim mods are achievement-safe. What is documented is that the Big Voice author answers "yes" to that question in their own Steam guide, and that ColorSelf deliberately gates the shiny palette behind a Steam check that you have already earned the matching achievement. Both are author claims, not tested results.

Top 15 Big Walk mods by downloads

Counts and versions are from Thunderstore on 3 September 2026. The three tooling packages above are excluded, since they are the plumbing rather than mods. Every description below is a paraphrase of the author's own README.

Mod	Author	Downloads	Version	What it does

ColorSelf	gugger	3,359	1.0.11	Choose head, torso and leg colours from the game's palette and have them reapplied each walk
Big_Run	BayTurtleKing	2,933	1.0.3	J toggles a speed and jump boost, both multipliers configurable, defaulting to six times

Big_Landing	BayTurtleKing	1,786	1.0.1	Removes the stunned pause and dropped item that follow a long fall
BigYeet	hsiddaz	1,766	1.1.0	Makes a carried friend behave like a held item so you can wind up and throw them
ShareChangedEyeState	gugger	1,757	1.0.11	Locks your character's eyes to a chosen expression and shares it with other players running the mod

Picks grouped by what you actually want are on best mods, and the complete package table is on all mods list. For the voice packages in particular, see voice mods; for FOV, graphics and third person, see visual mods; the lobby browser gets its own page at public lobbies.

Libraries, menus and where else mods live

Three of the top fifteen are not mods you notice while walking. Core is the smolMods library, BigWalkLocalizationAPI is a translation layer other packages register into, and ModSettingsMenu is a settings screen that automatically picks up any loaded IL2CPP plugin with normal config entries. Install those only when something you want depends on them, which a manager handles for you anyway.

Thunderstore is not the only host. Nexus Mods carries Big Walk mods as well, and several Thunderstore packages list a Nexus page as their home site, including Big Person View and SourceMovement; ModSettingsMenu goes further and lets an author register optional Nexus Mods or Thunderstore links alongside a mod's settings. Steam Community guides are a third source, mostly for install walkthroughs rather than files. This wiki does not link Nexus pages, and mod files hosted anywhere other than the author's own official pages should be treated with caution, exactly as the r2modman and Gale READMEs advise.

What this page does not cover

The Big Walk community includes packages aimed at flight, moderation and other host-side control, and a debugging explorer for the game's Unity objects. Mods built for cheating or for spoiling other people's sessions exist here as they do in every Thunderstore community, and this wiki does not write install or usage instructions for them.

Sources and last check

Checked 3 September 2026. Package versions, download counts, dependency strings, folder paths and multiplayer requirements come from the Thunderstore package pages and READMEs for BepInExPack_IL2CPP, r2modman, GaleModManager and each mod named above, at thunderstore.io/c/big-walk. Game facts, including the 12 Steam achievements, online co-op with crossplay and the 4 August 2026 release, come from the Steam store page. Patch 1.5.1 and its 28 August 2026 date come from the official House House Steam announcement, condensed on patch notes.

Everything a mod is described as doing here is the author's own README claim rather than something this wiki has verified, and the same applies to the multiplayer requirements table. The launch-from-the-manager instruction and the answer that achievements still unlock with Big Voice are player-reported, taken from the mod author's Steam guide. No developer source addresses modding, so whether mods affect achievements is marked not confirmed yet rather than answered.
