Tons of bugfixes

The ME3Tweaks team has focused on fixing bugs that lead to frustrating debugging sessions when developing mods. We've also focused on improving performance such as better redraw time, hardware acceleration, and fixing memory leaks.

High DPI support

The ME3Tweaks Fork of ME3Explorer has had multiple tools rewritten from the ground up that support much better scaling than the old tools did. This means your 4K monitor will actually be usable when you're using the toolset.

Actively developed

The ME3Tweaks Fork of ME3Explorer is the only actively developed version of ME3Explorer. Join the ME3Tweaks Discord to make your voice heard and influence the development of the toolset.


Below is just a sample of some of the tools used to develop mods for the Mass Effect Trilogy.

Package Editor

Edit packages, properties, and more in Package Editor. Newly rewritten for the ME3Tweaks Fork, Package Editor is the swiss army knife of the toolset that enables editing of almost everything.

Sequence Editor

Modify kismet sequences to create your own flow of the game, from conversations to combat. The new version written for the ME3Tweaks Fork works with Kismet Logger for debugging and automatically can logically layout a sequence.

Pathfinding Editor

Edit pathfinding networks to allow movement from non-player characters. Move, add, or remove level objects to customize the world.

Dialogue Editor

Modify conversations with easy with Dialogue Editor, including interrupts and charm/indidate requirements, FaceFX, and audio.


Listen to audio from all 3 games. Replace audio quickly and easily in Mass Effect 3 without having to use the Wwise authoring interface.


View and replace meshes for all three games with Meshplorer. You can even port (in limited cases) meshes from ME1 and ME2 to ME3.
