Mortal Kombat 1, like many of its predecessors, has a lot of unlockable items for players to earn. There are alternate skins for each fighter as well as a variety of other cosmetic odds and ends. In order to unlock most of the cosmetic items, players will need one of the four currencies in MK1: Koins, Dragon Krystals, Krowns, or Seasonal Kredits. Each one is earned differently; Koins are earned through daily and weekly quests and leveling up, but players might be wondering how to get their hands on the Dragon Krystals, since they unlock all sorts of premium items.
