📦 Installation

Prerequisites

• Lethal Company (Steam)
• BepInEx 5.4.x
• .NET Framework 4.7.2 or newer

Installation Methods

1. r2modman (Recommended)

   • Search for "LethalMic" in the mod browser
   • Click install and enable in your profile

2. Manual Installation

   • Download the latest release
   • Extract to BepInEx/plugins/LethalMic
   • Launch the game

📦 Dependencies

LethalMic requires the following mods to function correctly:

• BepInExPack (BepInEx-BepInExPack) - Core modding framework
• InputUtils (Rune580-LethalCompany_InputUtils) - Advanced input handling for Unity mods

These dependencies are automatically handled by r2modman/Thunderstore, but if you install manually, ensure both are present in your BepInEx/plugins folder.

Technical Note: When specifying InputUtils as a dependency for Thunderstore/r2modman, use the string: Rune580-LethalCompany_InputUtils-0.7.10 (with underscores, not dots).
