Guerrilla Games managing director Herman Hulst made an appearance on Late Night with Jimmy Fallon to demo Killzone: Shadow Fall.
During his appearance, Hulst discussed the new DualShock 4 controller, stating that radio messages being broadcast in the game will come through the controller's speaker. A bit of an interesting note, there.
While the footage is from the same section as Wednesday night's reveal, Fallon's desire to try the game confirmed it is in a completely playable state. He is given the controller towards the end of the video and does an excellent job of butchering the ISA's quest to eliminate the Helghast threat.
