'Crysis 3 features full-performance motion capture which is a first for Crytek.
Film and TV actor David Kennedy who currently plays the character Michael 'Psycho' Sykes in Crysis 3 speaks to Matt Cuttle about acting in the 'volume' -- the space in which the motion capture is recorded.
Unique to acting in a first-person game is that the actor playing the main character Prophet acts as the camera as he interacts with fellow actors. The actors perform around markers and scaffold poles and use storyboards and mock-ups for reference and speak to the director to help them understand the environment.
David quotes Crysis 3 director Steven Bender when he says that actors will still be integral to movies and video games as they raise the bar when performances are captured for animation in films such as Avatar.'
