Dual Play is a new gameplay feature in Batman: Arkham Knight.
In combat, any active combos are kept when switching, allowing players to keep their combo going. If a special move was available, the players could change the character without losing it. An additional circular meter appeared on screen, and was filled by performing any combat moves. Once it was full, the player could instantly take out any enemy upon changing character.
In Predator mode, the player needs to be out of sight and on a vantage point to change characters. They could command the NPC character to take out any normal sized enemy upon changing character, up to three times. After the three uses are consumed, the player could still change character, but could no longer instantly take out enemies upon doing so. If there was an another character present, Minigunners could be instantly taken out by sneaking behind them and pressing the takedown button. This however, was noisy, and often attracted the attention of nearby enemies.
In free play, the Batmobile works similarly to the Dual play characters, as it is summoned/entered with the same button which is used for switching characters. If the car is near to Batman during combat, the circular dual play metes appears, and when filled, Batman can perform an environmental takedown.
There are three major instances where Dual play is involved on story mode, Robin as part of the main story, Nightwing during the Gunrunner side mission, and Catwoman during Riddler's Revenge side mission.
