What ME3Tweaks Mod Manager is

ME3Tweaks Mod Manager organizes mods for the original Mass Effect trilogy and Mass Effect Legendary Edition on Windows. It installs mods with one click, including directly from archives, and can identify installed mods and detect conflicts. Its backup and restore tools offer granular or full game-file restoration, support automatic texture LOD settings, and can repair corrupt mods through cloud repair. It also handles MixIns, Custom DLC, and ASI mods.

For maintenance, the manager updates itself directly from ME3Tweaks and supports automatic mod updates. Its NexusMods integration lets users endorse mods and receive update notices for library mods from whitelisted developers. Mod creators can generate blank DLC mods, check for broken textures and other common issues, and compress mods for deployment. The application can also download and offer updates for ME3Explorer (ME3Tweaks Fork), Mass Effect Modder, and ALOT Installer from their GitHub repositories. The project is GPL-3.0 licensed. It is free, with use requiring Windows 10 22H2 or Windows 11 24H2 or newer and an official copy of at least one supported Mass Effect game. Disk space for backups and administrator privileges may also be needed.
