Lethal Company Best Mods 2026: Top Thunderstore Picks You Need to Install

Lethal Company’s base game is one of the best cooperative horror experiences available, but the modding community on Thunderstore has built something even more extraordinary on top of it. The right mod combination can expand your lobby from 4 to 16 players, add voice-morphing creatures that weaponise your friends’ recorded audio against you, and fill the ship with dozens of cosmetic suits that make every mission more memorable. This guide covers the definitive Lethal Company mod list for 2026 — the Thunderstore picks every group should install before their next shift. New to the game? Start with our Lethal Company beginners guide first. For step-by-step installation instructions, see our guide on how to install Lethal Company mods.

Important compatibility note: Every player in your lobby must install the same mods at matching version numbers. Lethal Company has no built-in mod sync system. If you install More Company to allow 16-player lobbies and a joining player doesn’t have it, the connection will fail or crash. The simplest fix is r2modman profiles — export your exact mod list as a code and share it with your group before each session. We cover this in the Compatibility Tips section below.

What Is Thunderstore and How Do You Use It?

Thunderstore at thunderstore.io/c/lethal-company/ is the official mod repository for Lethal Company. All mods are free to download. As of 2026, the repository hosts over 5,000 mods spanning quality-of-life improvements, horror content additions, new moons, cosmetic expansions, and complete gameplay overhauls. It is maintained as the community-sanctioned hub and is where every mod on this list lives.

For the full co-op setup, see like lethal company.

You have two ways to access Thunderstore:

• Direct browser download — Browse thunderstore.io, find a mod, and download the .zip file to install manually into your Lethal Company data directory.
• r2modman (strongly recommended) — r2modman is a free, open-source mod manager that connects directly to Thunderstore. It handles downloading, installing, updating, and organising every mod automatically. Crucially, it creates profiles — exportable snapshots of your exact mod configuration — which you can share with friends for guaranteed compatibility.

To set up r2modman: search ‘r2modman’ on Thunderstore or download it from the r2modman GitHub page. Install it, select Lethal Company as your game, and browse or search the mod list inside the interface. Installation is one-click and r2modman handles all file path management automatically.

Essential Mod Stack at a Glance

Quality of Life Mods (Must-Have Foundation)

These four mods form the essential foundation for any modded Lethal Company session. Install them in the order listed, starting with LethalLib, before adding any content or gameplay mods.

LethalLib

LethalLib is a shared modding framework that provides core functions other mods depend on: custom item registration, moon routing integration, network synchronisation, and in-game shop item management. As of 2026, over 50 mods on Thunderstore list LethalLib as a hard dependency, including several entries on this list.

Install LethalLib before any content mods. In r2modman, it will be flagged automatically as a dependency when you install a mod that requires it — but adding it first manually avoids any dependency resolution ordering issues. LethalLib has no visible impact on gameplay; it runs silently as the technical foundation that makes the rest of this guide possible.

More Company

More Company is the single most downloaded mod on Thunderstore and the one that most fundamentally transforms the Lethal Company experience. The vanilla lobby cap is 4 players. More Company removes this restriction entirely, allowing groups of up to 16 players to join a single session.

At 8 or more players the game’s dynamics shift significantly. Quota pressure becomes a collective challenge. You have enough crew to run two simultaneous facility teams or mount a coordinated extraction from a high-difficulty moon. At the same time, the ship becomes genuinely cramped during debriefs, creature encounters with many targets turn chaotic, and the communication overhead alone produces its own comedy alongside the horror.

More Company also extends the lobby HUD to display all connected players’ suits and status simultaneously. The host must have More Company installed and set the player limit when creating the session. Every player in the lobby needs the mod to connect successfully — this is a non-negotiable group install.

Combined Status

Lethal Company tracks three gameplay values that directly affect survival: sanity (low sanity attracts more creatures and can trigger audio hallucinations), stamina (sprint duration before your character slows), and weight (scrap carry load, which reduces movement speed and stamina capacity). In vanilla, these values are either scattered across separate HUD areas or entirely invisible as precise numbers.

Combined Status consolidates all three into a single clean HUD element showing numeric values simultaneously. During an active facility run, having precise sanity, stamina, and weight at a glance — rather than inferring them from behavioural cues — is a direct decision-making improvement.

The weight display is especially valuable: knowing your exact carry load lets you decide whether it’s worth risking one more trip into the facility or smarter to cut your losses and return to the ship. This is information the game always calculated internally. Combined Status simply makes it legible.

Host Fix

Lethal Company’s network architecture creates inconsistencies between the host player’s experience and that of connecting clients. Some creature decisions are computed on the host’s machine, certain item interactions trigger correctly only for the host, and grab priority timing can behave differently depending on your connection role. These inconsistencies become more noticeable in larger More Company lobbies where fewer players will be the host.

Host Fix patches these network-side inconsistencies so that clients experience the same gameplay behaviour as the host. It is particularly important in 8+ player runs. Host Fix has no visual footprint — you notice it primarily through the absence of the friction it prevents. Install it alongside More Company and treat the pair as a single unit for any lobby above 4 players.

Content Mods

Skinwalkers

Skinwalkers is the most effective horror mod available for Lethal Company, and the one that most precisely extends what the game is already doing. The mechanism is simple and deeply unsettling: when Skinwalkers is active, certain creatures record short snippets of your group’s voice chat during a session. Then, at unpredictable intervals, they play those recordings back through the creature’s in-world position.

In practice, this means you might hear a teammate’s voice calling from around a dark corner — only to find a Bracken waiting at the end of the corridor. You might hear your own voice played back at you in a room you were certain was empty. Because Skinwalkers captures your actual in-session audio, the playback is perfectly recognisable as your crewmates’ voices — not generic sound effects.

The psychological effect is substantial. Skinwalkers directly undermines one of the few reliable information channels the vanilla game provides: if you hear a teammate speaking, they should be nearby. Under Skinwalkers, that assumption becomes a trap. The mod pairs naturally with Diversity (below), which makes creature movement and targeting less predictable through complementary means. For groups who want the full horror experience, Skinwalkers is essential.

More Suits

More Suits adds over 30 new cosmetic suit options to the ship terminal’s suit rack. Vanilla Lethal Company ships with a small selection of solid-colour suits. More Suits expands this to include thematic designs, patterned options, and distinct visual identities for every player in a large group.

In More Company lobbies of 8–16 players, visual differentiation is a practical necessity as much as a cosmetic preference. Recognising specific teammates quickly in a dark facility corridor or on the ship’s camera system is considerably easier when no two players look identical. More Suits syncs visuals correctly across all connected players as long as everyone has the mod installed — no shared suit selections required.

MoreEmotes

MoreEmotes expands Lethal Company’s minimal default emote set with a range of new animations: dance sequences, wave gestures, and expressive reactions. The practical value is social rather than mechanical — MoreEmotes gives your group tools for non-verbal celebration and communication between missions.

Surviving a creature encounter that looked impossible, returning to the ship with a manifestly overloaded haul, or watching a teammate get grabbed by a Snare Flea on their first step into the facility — these moments land differently with a fuller expressive vocabulary. MoreEmotes is the lightest-impact mod on this list in terms of gameplay, but it consistently contributes to the social energy of longer sessions.

Diversity

Diversity overhauls creature AI to make encounters more dynamic and harder to pattern-read. In vanilla Lethal Company, experienced players can memorise the behavioural rules for each creature: the Bracken retreats when looked at directly, the Coil-Head stops moving only when you maintain eye contact, the Snare Flea ambushes from ceilings after a fixed delay. Once you internalise these patterns, encounters follow predictable scripts.

Diversity interrupts those scripts by introducing more variables into creature decision-making. Creatures respond more dynamically to noise levels, the number of players nearby, and environmental cues. The Bracken doesn’t always retreat when spotted. Coil-Head timing becomes less reliable. Several vanilla creatures receive new micro-behaviours that expand their repertoire without completely replacing their core counters.

The result is that pattern memorisation alone is no longer sufficient for experienced players, while the additional unpredictability amplifies the tension for newcomers still learning baseline behaviour. For creature-specific counter strategies that remain effective under Diversity, see our Lethal Company tips and tricks guide.

Maps and Moons

LethalExpansion

LethalExpansion is the most comprehensive map expansion mod available for Lethal Company. It adds entirely new moons to the game’s routing system — not reskins of vanilla environments, but fully authored locations with unique facility layouts, exterior terrain, distinct creature spawn tables, and exclusive scrap loot pools.

New LethalExpansion moons are typically rated at higher difficulty tiers with correspondingly higher-value scrap, creating a risk-reward progression layer beyond what the base moon selection offers. Groups who have exhausted the vanilla moon rotation will find LethalExpansion substantially extends the game’s replayability. The mod requires LethalLib as a dependency and integrates cleanly into the standard moon routing terminal interface.

FacilityMeltdown

FacilityMeltdown adds a timed radiation event to specific facilities. After a set period inside certain buildings, an alarm triggers and a countdown begins. Players must exit before the timer reaches zero or take lethal radiation damage. The mechanic creates a hard deadline that forces groups to balance thorough scrap collection against the very concrete pressure of a closing window.

In vanilla, the only time pressure inside facilities is creature danger. FacilityMeltdown introduces a second, independent timer pressure. Facilities with meltdown events also tend to spawn higher-value scrap, making the risk calculus genuinely interesting: you might be carrying a significant haul with the alarm blaring and a Bracken between you and the exit. The high-pressure extraction moments FacilityMeltdown creates are some of the most memorable in modded Lethal Company.

Gameplay Tweaks

Helmet Cameras

Helmet Cameras adds a live security camera feed to one player’s visor, which the ship monitor can display. Vanilla Lethal Company restricts the ship monitor to static facility security camera feeds only. Helmet Cameras extends the monitor’s capability to include a first-person-style feed from a designated visor-wearing crew member, giving the ship manager dramatically more useful situational awareness.

The value is most apparent when one player takes a dedicated ship management role: monitoring scrap values, managing power routing, and watching camera feeds for incoming threats. With Helmet Cameras, that player can track crew positions in real time and call out threats the field team can’t see from their own perspective. In 8+ player More Company runs with a dedicated ship manager, the difference in information quality between vanilla and Helmet Cameras is significant.

ShipLoot

ShipLoot adds a persistent display showing the exact total value of all scrap currently stored on the ship. In vanilla, determining whether you’ve accumulated enough value to hit quota requires either using the sell terminal (which only tallies as you sell) or manually estimating values item by item.

ShipLoot eliminates quota guessing entirely. You can see the running total at a glance at any point during or between runs, enabling precise planning: you know whether you need another moon sweep or whether you’re already clear to fly to the Company building and sell. For efficiency-focused groups optimising their quota cycles, ShipLoot removes one of the most consistent sources of poor decision-making in the late-session phase.

Compatibility Tips: Keeping Your Group Aligned

Modded Lethal Company requires every player in the lobby to run an identical mod configuration at matching version numbers. Here is how to stay aligned and avoid the most common causes of connection failures and crashes:

• Use r2modman profiles to share your exact mod list. In r2modman, open your profile and select ‘Export Profile as Code.’ This generates a short string that any other player can paste into their own r2modman to instantly replicate your entire mod list at the correct versions. Share this code in your group chat before every session.
• Update mods together, not independently. When a mod on your list receives an update, notify the group and update simultaneously. If one player updates More Company to a new version before others, connection failures will follow.
• Never join a lobby with a mismatched mod list. If a joining player has mods the host lacks, or is missing mods the host has, expect either a failed connection or mid-session desync. This is the expected behaviour of a system without built-in mod synchronisation — not a bug.
• Keep a vanilla profile. r2modman supports multiple profiles. Maintain a clean vanilla profile (zero mods) so you can quickly switch back to diagnose whether a problem is mod-related or a base game issue.
• Check mod compatibility notes before adding anything new. Some mods explicitly list incompatibilities in their Thunderstore descriptions, particularly creature AI overhauls like Diversity that may conflict with other behaviour mods. Review the description and comments before adding any mod that touches creature logic.

Frequently Asked Questions

Do all players need to install the same mods for Lethal Company?

Yes — this is the most important rule of modded Lethal Company. Every player in the lobby must have an identical mod list at matching version numbers. There is no built-in mod synchronisation system. The easiest way to guarantee this is to use r2modman’s profile export feature so all players download the exact same configuration from a shared code.

Will installing mods break my save file?

Most mods are non-destructive to save data. Quality-of-life mods, cosmetics, and gameplay tweaks generally do not alter save files. Content mods that add new moons like LethalExpansion may affect save data if removed mid-campaign, as the custom moon entries would disappear from the routing terminal. Best practice: once you begin a campaign with a specific mod list, keep it stable for the duration of that run.

What is r2modman and is it free?

r2modman is a free, open-source mod manager available on Thunderstore. It handles all mod installation, update management, dependency resolution, and profile sharing automatically. It is the recommended installation method for every mod on this list. All mods on Thunderstore are free to download — some creators accept voluntary tips via links in their mod pages, but installation is always zero cost.

What happens if I join a lobby with mismatched mods?

You will typically either fail to connect, be kicked from the lobby immediately, or experience crashes and gameplay desync during the session. The most common scenario is version mismatches: both you and the host have the same mod, but at different versions. Always coordinate updates with your group and use r2modman profiles to eliminate guesswork. Persistent connection issues in a previously working group are almost always caused by a mod version mismatch.

Is modding Lethal Company safe?

Mods from Thunderstore are reviewed and used by the wider community, but always install from official Thunderstore mod pages rather than third-party sites. Use r2modman rather than placing files in game directories manually to reduce installation errors. Back up your save file before starting a heavily modded campaign as a precaution, particularly when adding content expansion mods like LethalExpansion.
