Bryan Dawson (Prima Games): Dragon Ball Xenoverse caters heavily to fans of the series. Just about everything you can imagine was included in the game, aside from beam struggles. That includes the ability to collect seven Dragon Balls and summon Shenron, who will grant you one wish. Once you summon Shenron you can wish for special armor or hidden characters to help further your progression.
Now that you know you can summon Shenron, the next step is to collect all of the Dragon Balls in a fast and convenient way. Many of the item drops in Dragon Ball Xenoverse are random. You may know what mission or quest to play through, but what you need to make an item drop is completely random, and even if you get everything, you need to find the item you're looking for. On top of that, you may not get that item.
