This is story related so it is unmissable.
When you get to Afterlife and you're fighting off a wave of enemies whilst doing a set of 4 objectives, you'll unlock this achievement as you kill the last enemy and the 4 objectives.
This is the third and final achievement. The only missable achievement is 'Meticulous' and you should have gotten that before this achievement.
I couldn't say anymore without giving spoilers but you should need to know anything else for this achievement to pop.
