Some may be locked even AFTER beating the story in Dragon Ball Xenoverse 2, unlock them with this method. Like Xenoverse 1, it also seems some are unlocked by talking to NPCs that start the PQ with you before its added to the list. Look for the blue exclamation marks on the map.
How to unlock all parallel quests in Dragon Ball Xenoverse 2
First thing’s first, make sure you beat the game because that means you are at your top notch game when starting parallel quests. So, if you’re wondering, for example, why Parallel Quest 89 isn’t unlocked yet then to unlock it make sure you beat the parallel quest before it. In short, just start playing them in order and you’ll unlock them as you go.
On a side note: A lot of people have trouble getting the High Combo on the Hercules Quest. The main complain is that they can’t find a good spot to do it. Anytime they get a high enough combo, the enemy either teleports out or uses a ki skill. It might appear impossible and a lot of people are dumbfounded as to how to get a 42 hit combo. A basic solution to that is doing a combo and then quickly adding a meteor crash afterwards.
