This mod was built for a 16:9 screen ratio, and as such only works as expected at that screen ratio.
Alternatively install the binkw32 bypass from the tools menu. If you get a DLC authorization failed at the main menu, THIS MOD WILL NOT WORK PROPERLY, TO FIX IT YOU MUST START THE GAME USING 'START GAME' FROM MOD MANAGER. Mod Manager Mod Package 1.060 | Mod Manager Moonshine has been gone for several months so Dybuk and I have maintained it in the meantime, which is why it lives here now. This mod is installed through Mod Manager and was originally developed by MoonShine with fixes done by Dybuk and FemShep (me).
The multiplayer version is available here. This does not work with multiplayer and multiplayer is simply not available when this mod is installed. This mod brings the native Xbox interface to Mass Effect 3's Single Player.
