- The Cameo: Aisha Tyler appears several times in the game as herself. As does Phil Brooks
- Fan Nickname: Not Deadmau5 for Default.
- What Could Have Been:
- Early gameplay demos showed that the ctOS mobile app could be used in the main game to assist players with missions. This feature didn't make it to the final release; instead, the app was retooled into a competitive multiplayer mode where the console player races through a series of checkpoints under a time limit while the mobile player uses the app to activate hacks and deploy police in an effort to stop them.
- The E3 2012 demo has several graphical options that were locked deep in the PC version of the game, which was unlocked by a modder. While they do make the game look better, some people who have activated them have noticed the gameplay slows down a little.
