About this video

" ITEM is an ending mod which embraces the Indoctrination Theory, modifying dialogue and sequences during the final moments of the game, starting after Shepard enters the beam to the Citadel. This mod aims to build upon the theory and give a satisfying conclusion with a few loose ends as possible. "
