Although four hours still remain for the Scorpion Challenge Stage to be completed, the next iOS Injustice Challenge Stage has already been revealed by NetherRealm employees on the Facebook group Injustice iOS: Alliance Credits Hub. The group was formed to help players receive more Alliance Credits, which are received when your friends sign up to play Injustice from Facebook. For instance, the Joker in his Killing Joke attire can only be purchased with 60 credits, which means players must have 12 friends accept their invites to play, as each accepted invite is worth 5 credits. This sounds much easier than it actually is. Thus, if you are having issues unlocking Alliance Credits, then this group may be for you. Members frequently delete their apps, notify other members, accept friend requests, and then reload the app to accept Injustice requests and give others Alliance Credits.
The overall reactions to Scorpion being added to the DC card-fighter have been mixed. Some players love Scorpion’s special ability, which causes bleeding after a heavy attack combo. Bleeding causes any card-fighter to lose small amounts of health over time. However, other players were very disappointed with his lower health and strength stats. Either way, Scorpion is a classic annoyer who can cause long-term damage problems for teams.
There are currently three Green Lantern card-fighters available in the iOS Injustice game, but none of them are Gold level cards. Last, it has also been mentioned, but not confirmed, that after the Green Lantern Challenge Stage an update will be offered, and the Shazam card-fighter will become available.
