Teenage Mutant Ninja Turtles: Out Of The Shadows is a downloadable game published by Activision and developed by Red Fly Studio. Out of the Shadows is a four-player online co-op brawler with a "skill-based combat system built around combo-driven action." Out of the Shadows is not based on the 2012 series, but exists in its own "hyper realistic 3D-style" world inspired by the show. It was released on August 28, 2013. for Xbox Live Arcade and Windows PCs (Steam platform). It was initially scheduled for September 24, 2013 on PlayStation Network, but exactly one week prior, it was heavily delayed, eventually releasing on April 15, 2014.

The game was pulled from all digital stores in January 2017 as Activision chose not to renew the license.
