Backup and Restore

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

ME3Tweaks ModMaker

Want to mod your game but don't want to dedicate huge amounts of time? ModMaker was designed for you. Design mods in a web point and click interface.

Direct Mod Updates

No going to sites to download and extract new mods. Mod Manager will check for updates and directly update mods for you.

Additional Features

MixIns for any mod

Want to spice up a mod? Add MixIns to change things up like making all enemies hackable.

Mount.dlc Editor

Put that hex editor away, because the Mount.dlc editor will do it all for you. Enter your new values and your mount file is ready to go.

Selective Restore and Custom DLC Manager

Restore only the DLCs you want and delete the Custom DLCs that are installed without having to guess what the codenames are.

Direct Mod Manager updates

Mod Manager updates itself directly from ME3Tweaks; you don't need to hunt down and extract every new version as they come out.

Restore to a modded state

The basegame and unpacked DLC game repair database keeps a snapshot of your current gamestate, and when restoring files will restore to the snapshotted state.

Keybinds Injector

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