How to unlock the It Has Begun achievement in Injustice: Gods Among Us - Definitive Guide
Simply finish any mission in the S.T.A.R. Lab mode. It is not required to get 3 stars. I did this on a Red Son mission so I can confirm that those work for this achievement.
EDIT: Cornerscout has provided a fantastic video for this achievement and for Overachiever

This one is pretty simple, you should have it playing your very first challenge even without any Stars collected. Please refer to World's Finest for more details.
