Aran Tal is one of the newest characters in Star Wars: Hunters, and it is one of the only characters in the game not currently available through the typical means to unlock them. Most characters in the game can be unlocked just by playing the game. As you level up, the characters are slowly unlocked one by one, and it usually does not take long for you to collect most of them. However, Aran Tal is not like the others.
