The IOS version which was released on April 3, 2013, is a free-to-play game with buyable upgrades, such as Power Credits and Energy Cards. Recent updates have included DLC Characters such as The Red Son Pack (with Superman, Wonder Woman and Solomon Grundy) and the Man of Steel pack (it contains an exclusive Superman and Zod, availabe for a limited time only).
There also exists a Challenge Mode, which allows players to get exclusive Gold Character Cards by beating many battles within a certain time period.
The following characters can be claimed (that are confirmed) from Challenge Mode: Batgirl, Zod, Red Son Deathstroke, Regime Raven, Regime Aquaman, Blackest Night Batman, Hawkgirl, Elseworld Flash and Martian Manhunter, John Stewart Green Lantern, Mortal Kombat Scorpion, 600 Wonder Woman, Containment Doomsday, Boss Solomon Grundy, and Darkseid.
NetherRealm teased at WonderCon a multiplayer trailer, adding new skins for existing characters and a new multiplayer system with a genuine new interface, coming soon to Injustice Mobile.
Injustice for the iOS features different gameplay than it does on its console version, resembling more of a card battle game rather than it's "fight-style" console counterpart. Players collect characters in the form of cards and use them on 3v3 battles to defeat their opponents.
The player starts with three random Bronze characters at the beginning of the game, and can get more characters by completing specific battles, buying them from the shop, or earning them as rewards from the Challenge Mode. Every character can level up to Level 40, and buying more copies of characters allows you to promote them, from Elite I-V; every "Elite" on the character has bonuses towards Damage and Health. Character cards come in three rarities; Bronze, Silver and Gold. The higher the rarity, the better base stats come with the character. Each character has a "Passive Ability" which grants them a boost in gameplay for themselves or for the whole of the team. (For example: Superman Regime gains 50% more damage for 6 seconds at 40% health). They also have two Special Attacks which are unlocked at Levels 1 and 5 respectively. The higher the Special Attack, the more powerful it is. The first two Special Attacks can deal Special Effects such as Poison, Bleeding, Frozen, or Stun the opponent. The level 20 attack is a Super Move which is a High-Damaging UNBLOCKABLE Attack.
Each battle has a requirement of "Energy" to use before a battle starts, as many as 1-3 Energy may be used for battles. Each character has 10 Energy slots that recharge over time. If a character lacks the energy to participate in a battle, the player must wait until it is recharged or use an Energy Consumable, which can be rewarded from matches or as daily rewards. Energy can also accumulate faster for cards with the purchase of a "Support Card" for each character found in the shop or from "Booster Packs". Cards that boost Health and Damage can be found as well.
The Challenge Mode is a event that happens usually twice a month, that may last for 10-17 days. It consists of 63 battles within five certain "Sub-Challenge Stages". Each of the five challenges has a certain requirement in order to beat them or even partake in them. One example is that one of the parts of the challenge may require the player to have Bane on their team, which includes Bane, Regime Bane, or Knightfall Bane.
The battles within the challenge mode have an Energy Cost and an extra cost known as "Challenge Tokens". Tokens are won by doing ladders outside the challenge mode in quantities of 1, 2, and rarely 3. Every time a challenge starts, 25 tokens are awarded to the player to get started. Without any losses, a total of 63 tokens is required to beat the challenge mode completely. Tokens can also be bought from the shop in quantities of 3 or 20. Tokens disappear from the player when Challenge Mode ends. When a Challenge Mode is completed, a "Gold" character will be awarded to the player. Other rewards include a free Bronze booster pack, 15,000 Power Credits and a Silver booster pack. Once Challenge Mode is completed, the player may buy the same character again to promote them. If the player has not completed it, they will not find them there. As of yet, challenge mode characters cannot be found in booster packs.
In the 1.7 Update, Challenge Mode will be repeatable up to three times if eligible. This is ONLY from Elseworld Flash onwards. For example, the challenge with Elseworld Flash will be repeatable so that's it possible to claim the prizes three times. However, with each repeat, the challenge mode gets significantly tougher; the difficulty starts from Normal, then to Expert difficulty and finally Nightmare difficulty. The same mechanic of completing the challenges one by one to get pieces for prizes will still apply. In higher difficulties, players may be rewarded with character cards of bronze or silver rarity, or very rarely gold. In the Expert difficulty, it takes 2 Challenge Credits in every battle and in Nightmare difficulty it takes 3 Challenge Credits per battle up from the original one required. Therefore, it'll take 63, 126, and 189 (a grand total of 378 credits) to complete the Challenge mode fully.
These characters were rewards from previous (or ongoing) challenge modes.
Batgirl was brought back from NetherRealm due to customer feedback. It is unknown if this will apply to old challenge characters as well.
