So I came into the invasions and managed to team wipe this team with a missle barrage with all of the deaths within a second of each other. Now you would think that would count as rapid kills for this triumph, as it would turn out it does not. So I am genuinely curious what does the term "rapid kill" actually mean on this triumph? Cause getting a triple kill yields no progress and idk if there is anything else to try for this to work.
