Power Credits are the main currency of the game and are earned by winning matches in any battle - Standard, Online, Challenge or Survivor and preferably Breakthrough Mode - as well as by selling cards back to the Store for 30% of their store price. They can be used to buy packs, most characters, support cards, and upgrades to Special Attacks and Super Moves. They can also be used for direct Promotion(s) and for unlocking Gear slots as well as fusing and evolving gear cards.
In the 2.5 update , NetherRealm Studios added a feature in-game that allows users to watch videos for free power credits, to compensate for posts on the forums regarding them, as well as promoting advertisements. However, the amount can be different each time, ranging from 1 - 2,500.
Bonus Battle 6 (the battle with the white star on the sixth page) is widely regarded as the best battle to earn credits/"grind", yielding a total of 20,850 (1,950 + 4,620 + 4,690 + 4,760 + 4,830) credits per run!
When the player finishes a boss/bonus battle for the first time, they are awarded an immense amount of power credits, and possibly characters/cards. The highest reward comes from the last Bonus Battle, which yields 79,200 credits and a Gold character upon completing it for the first time.
Credits Per BattleEdit
Based on this chart, the most efficient battles for each screen are battle 5, bonus battle 2, bonus battle 3, battle 25, battle 32, bonus battle 6, and bonus battle 7, respectively.
Double Bonus Power Credits is an event (usually on a weekend) that occurs once every few months. It allows players to gain double power credits for victory in any standard, online or challenge match, including one-time bonuses on the first completions of standard battles. It will not double the credits earned from survivor matches.
Buying credits with real life moneyEdit
Power Credits can also be bought from the digital store (ex. Apple Store) for real-world money. Prices vary dependent on the credit amount requested, and the price was raised in the 2.4 update.
