I should also clarify that the controversy surrounding the loot boxes is a little overblown because if you manage to do most of the side content and atleast some of the minor online missions, you will end up with more than enough gear to get the true ending of the game. (gearnuke.com)
When you do, you'll be treated to a little more content than if you finish the game without the emeralds — and that will lead you to the final, true ending of the game. (vg247.com)
Kent's route is not the true ending of the game and it begins rather awkwardly. (nerdmuch.com)
