Upgrade to ME3Tweaks Mod Manager, which supports all 3 games and is fully backwards compatible.


Backup and Restore

Backup and restore your game files to quickly change between mods. Restore MP, SP, or everything in 2 clicks.

ME3Tweaks ModMaker

Like modding gameplay? Don't like spending tons of time figuring out how the engine works? ModMaker was designed for you. Design mods on the web.

Direct Updates

Mod Manager updates itself directly from ME3Tweaks. When an update comes out, you're one click away from being up to date.

Additional Features

Developer Tools

Generate blank working DLC mods, edit mount.dlc files, compress mods for deployment (for both Mod Manager and manual installation), dump PCC data into easily searchable files - just to name a few of the tools.

Restore only what you need

Restore only the DLCs you want, and delete the Custom DLCs that are installed without having to know the specific name of the DLC folder - Mod Manager looks it all up for you.

Tools from start to finish

Mod Manager can download other modding tools on demand directly from their Github, including ME3Explorer (ME3Tweaks Fork) and ALOT Installer. It'll even offer to update them when your local copy is out of date.

Mod multiple game installations

Have multiple copies of game files laying around? Mod Manager can update your game's registry key so you can boot and mod other installations of the game.

Drag & Drop Automation

Drag and drop all sorts of files onto Mod Manager to perform batch tasks, with things like TLK, Coalesced, PCC Data dumping, mod importing and more.

Keybinds Injector

Use custom keybinds but like MP mods? Inject a custom BioInput.xml file into mods so your keybinds move with you. You can also quickly fix the Talon Mercenary keybindings.
