The Extended Cut to Citadel is a mod that extends the ending of Mass Effect 3, adding a new plot twist that works with the extended cut of the game. It works with all endings and allows you to send a message from the game to the real world.

The mod also adds the option to disable the splash screen.

You need to install this mod with the Extended Cut ending and it will send you from the credits and clicking the message from Bioware straight to the Citadel DLC apartment. It will work even if you've started some of the Citadel DLC.
