This Level is 2 of 5 of the Justice League Story Missions, and this is a unmissable achievement as it’s for natural story progression.
Level 17 - “Man To Mantis”
*** Spoiler - click to reveal ***This level is very short compared to the main story levels and has no major confusing puzzles to tackle, you have a short 5 heart Boss (Mantis) to defeat and then level over.
As soon as the cinematics cut in pop achievement unlocked.
Congratulations
Happy Hunting
