This achievement is unlocked during the plot point in Act 3 Chapter 4 where
*** Spoiler - click to reveal ***the large Swarm Leviathan thing is trying to pull down the rocket launch tower, of course while you're in the middle of trying to launch said rocket. Upon the conclusion of running down falling platforms and having to stop and shoot glowing orifices on said giant monster you'll eventually come to the conclusion of this act and chapter via the secured launch of the satellite rocket for the UIR Hammer of Dawn.
