So I've noticed there are a few enemies in the game that are kind of invisible, there is only an outline of them visible. Kind of exactly like in the first Darksiders the invisible chests that you needed the mask to see. But I just finished the game and have not found any item to see then yet. (also have 2 ability slots unsused weirdly). I heard there was a quest to kill them from the Master move trainer, but there is no such guy in the game, only basic and advanced.
Anyone figured it out yet?
While we are on topic of secret stuff. Wicked K is supposed to be in the game looking at the achievements, anyone found him yet?
