Development Injustice: Gods Among Us was first announced on May 31, 2012. According to Ed Boon, the main goal heading into Injustice was to create a game outside of the Mortal Kombat series that was dramatically different within the fighting game genre. Producer Hector Sanchez stated that NetherRealm Studios did not feel constrained by the parameters of Mortal Kombat, allowing the developers to take more design risks with Injustice, such as removing Mortal Kombats traditional dedicated block button. Similar to Boon's previous DC-related title, Mortal Kombat vs. DC Universe, the use of the DC Comics license implied restrictions to the amount of violence in the game; however, Boon intended to push the "Teen" rating by replacing violence with "crazy, over-the-top action." When questioned if the studio's past experience with Mortal Kombat and its characteristic violence would influence Injustice, Boon replied that he wanted to keep the two titles as separate entities. The online mode in Injustice was built upon the foundation laid from Mortal Kombat. Due to complaints about severe lag in the online multiplayer portion of Mortal Kombat, Boon reported that the development team had looked back upon their past mistakes and created a "new, more elaborate system" for an improved online experience. Senior Producer Adam Urbano stated NetherRealm Studios spent two years of development focusing on netplay. During development, NetherRealm shared their idea for an automated system to push Injustice downloadable content to all users' consoles. The game would connect to the Internet during use and automatically download the information required for players who have bought DLC characters to play against others who have not. The system also allows NetherRealm to quickly send hotfixes to patch noticeable glitches. Like Mortal Kombat vs. DC Universe and Mortal Kombat, Injustice runs on the Unreal Engine 3,
