In 2013, NetherRealm Studios and WBIE released Injustice: Gods Among Us, a fighting game showing what could happen to Earth if Superman had gone rogue. Luckily this scenario happened "only" to an alternate Earth. The heroes from the "main universe" arrived to assist the remaining heroes of the alternate Earth to oppose the rogue Superman and his army of heroes and "former" villains. At the same time, a popular free-to-play smartphone app was released for iOS and Android devices. The smartphone version was unique in the way that it introduced several new characters not available to the console and PC-versions of Injustice, such as the BTAS Harley Quinn, the Arrowverse-version of The Flash (played by actor Grant Gustin) and Reverse Flash, two versions of Darkseid, Cassandra Cain, Green Lantern/Jessica Cruz, the Suicide Squad-versions of Deathstroke, Harley Quinn and Jared Leto-Joker, among others. While the game could be played offline, it didn't have a story mode. 4 years later, in May 2017, the story on the alternate Earth continues in the sequel Injustice 2. And as usual, we'll get a smartphone version based on it. Since February 13 2017, it is also possible to pre-register it, just go to your local Google Play/AppStore to do so. Does it mean that NetherRealm Studios will shut down and delist the original Injustice from AppStore and Google Play when the sequel is released? One Injustice mobile-fangroup on Facebook doubts it, but no one can know for sure... Here's a gameplay video from the mobile version... EDIT: which can only be watched on YouTube.
