About this mod Author’s original text
Lethal Company v69 - The MephPack (v1.4.1) [102 mods]
After countless hours of playing Lethal Company with my friends, we've curated the ultimate collection of mods to enhance every aspect of the game. From terrifying soundscapes to unique mechanics and quality-of-life improvements, this modpack represents everything we've loved while playing together.
What started as a fun project to make our sessions more enjoyable has grown into a polished and well-organized modpack that we're now excited to share with the community. Whether you're a seasoned veteran or new to the game, this modpack is designed to elevate your experience and bring even more thrills to your gameplay.
NOTE There are a lot of different beautiful mods in that fandom right now and a lot of them could be also added, but we have chosen that one because we like them the most. Feel free to remove or add mods that you like or dislike. Be creative! But also remember that not all of them are compatible. The current build is stable from what we have experienced and a modpack has had a lot of iterations. So wether you want something that you can install & play immediately or use as a base for your own build - feel free to experiment!

Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.
Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.
Install these first, or the mod will not work:
