This video contains spoilers for some early and late game moments from the base game and for the Phantom Liberty DLC. I recommend you play / watch them before proceeding with this video.
For this video I am only including Flatlines that have a unique moment to them, usually done in cutscenes or the deaths are changed and tailored instead of the usual falling over to the side death animation we see in normal combat.
Not all deaths are included, if you know of any that I've missed please let me know and I'll make a Part 2. *I am aware I missed the Chimera QTE deaths very early after rescuing Rosalind.
