To get one of the Hunter Badges, go to the Twin Axis server. When you are at the part with the Sonic statue, Bit says "There is a secret with this statue, lets look around." To find the secret of the statue, go behind the pillars. You will see a small white dot. Attack the buttons. There is one on each pillar. The first one is on the left of the arch way that you need to find the repair program for. Next, go to your left and skip the next one. Attack the one after it. Again, go to your left, skip the next one, and attack the one after it. By then the next one should be the one to the right of the unrepaired door. Do not attack that one yet. Next, attack the pillar that is directly across from the last one you hit. After hitting the last two an intermission sequence will start. Sonic will start to spin, fly into the air, and turn into Super Sonic. As this is happening he will drop a three star box that has a Hunters Badge in it. Note: You need a three star Virtua Soul to get it.
Master Course
There is a final training area available only once a player reaches ExA level 3. The second requirement is that you have all of the Hunter medals that can be located in the three-star boxes, one in each of the seven first servers. You require a level 3 skill to open them. Once you collect all seven, return to the Low A room and talk to the training instructor that you speak to every time to increase your Hunter rank. He will then say that you have the opportunity to try the Master Course. It is incredibly difficult and lengthy. This is far harder than anything you will encounter in the normal story mode.
