Instead of having all unlocked characters available for purchase, the system is now changed to show only 3 characters (Bronze, Silver or Gold) rotating every 12 hours. Players were also able to buy characters as many times as they want, but the new system only has players able to buy character cards only once and wait for the next 3 characters to show up.
 * New Quests have been introduced, taking place in the Netherrealm (if players have completed the Outworld portion of Quest Mode, a portal will appear in the middle of the Quest map. Tapping on this portal with transport the player to a new map, with new Quests with exciting rewards).
 * Background music during battles have changed entirely.
