I received this achievement despite not even coming close to the three elims required for it. I only managed 1 elim and one immortality field destroyed. At the end of the ultimate there were still 4 enemies alive but I had already gotten the achievement.
I mean, I guess it’s better than the achievement being unobtainable like Mauga’s Heartthrob… but I’d still prefer if they just worked properly in the first place.
Replay code: X87ZYE. Achievement received on my first ultimate at the end of first checkpoint.
