I compiled most of the Renegade interrupts i could find in my playthroughs of Mass Effect 3. Some of the most douchebaggery and badass moments come from some of these interrupts and full of spoilers. There's a good chance i missed some so comment below and let me know.
I also did a Mass Effect 2 version below.
