In a more or less near future, the Black Ops soldiers and the General Dade will see their abilities increased thanks to armor, as well as the DNI system IDN in the French version of the game. This system is directly implanted in the brain and spine of the soldiers, allowing them to communicate with each other and with HQ. They can also connect to any gear and take control of it. The soldiers also have robotic limbs replacing those they previously possessed, less effective. Treyarch announced his desire to make the solo less scripted by letting the player complete the mission the way he wants.
