ME3Tweaks Mod Manager is a mod manager that supports all three Mass Effect trilogy games, as well as all three legendary versions of the games, plus the Legendary Edition launcher. This program is designed to make it easier to install mods for the Mass Effect series for end users. It has tools for developers, as well as advanced game diagnostic features that can be used to troubleshoot both the program itself and games.

ME3Tweaks Mod Manager is also known as M3.

How to install a mod
  • Make a game backup before you install any mods (in the Backup & Restore menu) DO NOT SKIP THIS STEP
  • Drag and drop your mod download onto the interface (or use Download with Manager feature on NexusMods)
  • Click Import to import the mod into the library (this allows update detection for opted-in mods and other features)
  • Select the mod and click Apply
You don't need to run the game through Mod Manager. But for Legendary Edition games, you can turn on the autoboot option in the settings to automatically boot the selected game when launching it from Mod Manager.

How to remove a mod or restore the game
If you made a game backup:
  • You can restore granularly (enable/disable/delete DLC mods, restore specific files) by clicking 'Manage Target'. Note that texture modded games will have limitations on restoration due to how texture modding modifies the game.
  • You can mirror your backup onto your game by using the Restore menu item at the top of the main window. This will make your game match your backup directory. 

If you didn't make a game backup:
  • Unfortunately your only option to reliably reset the game is to delete the entire game directory
    and redownload it from EA App or Steam or other online storefront.
    Repairing or uninstalling/reinstalling will not work as it does not remove extra files added by various mods


Manually copying your game backup will likely result in Mod Manager not recognizing your game, as it has a 'cmm_vanilla' file that is used to force Mod Manager to reject it as a modding target.

Note that texture mods cannot be 'uninstalled', simply due to how the game engine works.

Mod installation order
Mods need to be installed in a specific order in order to properly work.

  • Content mods - M3 installs these.
  • Textures (.mem files) - These must be installed after all content mods or the texture map will become desynced. Textures can be installed in M3 via the Batch Installer feature (to ensure installation order), or through Mass Effect Modder (available in the Tools menu). Mod Manager will warn you if you try to install content mods after textures, DO NOT DO IT.

Tools for mod developers
Mod Manager includes many tools for developers, accessible by turning on developer mode in the settings. This includes things like DLC mod Starter Kit, mod deployment to 7z (with a whole suite of mod checks), access to many developer tools right in the Tools menu, and more.


A note about LE1 Coalesced Files
Mod Manager 8.1 supports merging ConfigDelta files together to create a new Coalesced_INT.bin file for LE1. This has a side effect of disabling the ability to manually edit or replace the one used by the game. You can turn this feature off in the settings; however, you will break all mods that use this feature (of which there will be an increasing amount).

If you wish to use the changes from your Coalesced_INT.bin changes for LE1, you need to port the changes to the M3CD format, which is fairly simple to do.


Operating Systems
Supported operating systems include currently supported consumer editions of Windows. Versions that are no longer supported by Microsoft for the general public will not be supported by me.

- Windows 10
- Windows 11

Asking for support for other operating systems will be ignored.

Unsupported operating systems may still run Mod Manager. If it works for you, great, if it has issues, you'll have to find your own solution to the problem.

Disk Space
Disk space requirements vary based on how much you backup and what mods are installed. A game backup will take up as much space as the game (but can also take less).

Network connectivity
Internet connection is required for dynamic features such as the Third Party Importing Service. While an internet connection is not required after the first boot, some features will not work as well without a connection to ME3Tweaks or GitHub.


Support for ME3Tweaks Mod Manager and other ME3Tweak services and products are handled in the ME3Tweaks Discord.

Is your game(s) pirated?
Unofficial copies of the games are not supported.

Is your game cracked but "you bought the game"?
Cracked games are not supported.

Thanks for using my software. It means a lot that I can create tools for others to use.
