Description
Destroying enemy constructs is useful, but destroying the ones who keep them running is even better. The Golden Maw use these machines to repair their damaged constructs. If you tampered with them, I bet their engineers would come running... right to the slaughter.
Upon completion
Killing the Golden Maw Engineers ought to slow down the cultists for awhile. At the very least, it'll give Defiant engineers more time to figure out their technology.
