But whoa, I just had an idea. What if: ok the ending WAS indoctrination, shepard snaps out of it, gets to the beam. He has to make his way through the citadel to get to the catalyst, however Harbinger's influence is even stronger in the citadel. The player has to navigate an injured shepard (though not as slow moving) through warped corridors and rooms, inspired by past traumatic experiences in ME1 and ME2 (subtle of course), magnified by Harbinger's maddening indoctrination attempts. Ever played the original Max Payne? Remember the nightmare sequences? Similar to that I suppose. He has to confront the ghosts of his past of allies he couldn't save, and enemies that just won't fade from his memory (such as saren). He might re-live past sequences throughout the entire series, but with Harbinger's own sick twist to each one. He may have to battle ghostly doppelgangers of lost squadmates, and make the hardest decisions in the form of dialogue, but the player's choices rarely play out as they plan, since Harbinger always comes up with a unique way to twist the player's choice into something they do not want. Perhaps shepard's eyes can glow yellow (assuming direct control) during these sequences, as shepard makes his way through the deranged citadel as well as the vast abyss in the darkest depths of his mind. Upon completing the trip through the citadel, shepard gets to the catalyst (no child since harby already tried that), and this is where there has to the that twist bioware compared to "Luke, I am your father". Shepard has the final showdown against Harbinger (standard end game boss fight) and....ah I'm just pulling stuff out of nowhere really. I'm not sure how TIM is going to fit in to all of this but hey, sounds like a neat idea. What do you think?
