M, I feel like IGN's guide is off. I read their list of endings and watched the videos. I know I got the bad ending with a low rating cause I rushed through the game.
And my ending was the same as the "perfect 5000 destroy reaper's ending." That can't be right. In their own guide, they say with the 5k rating, Shepard lives, but that video clearly showed him dying.... so, there's gotta be something off with their videos.
