So far we knew the DLC Extended Cut of Mass Effect 3 would add new scenes to different endings to better clarify the points remained in abeyance. After the release of the content we discover though that BioWare has added an additional final: more details below, with the caveat that we speak of the end of a game and then do not continue if you haven't completed the title and you don't want to ruin anything.

The three choices (or two or one, depending on the level of Galactic Reactivity with which it has arrived at the end) that we are subjected by the child/catalyst on the fate of the Raiders, it adds a "rejection" in which we may refuse to make a decision so important and seeing this thing lead (this option can be activated also by shooting the catalyst). Below is a video in English that shows this fourth option, which of course we suggest you view only if you're not going to experience it in person within the game.
