We all think we know Optimus Prime, but that doesn't mean we can't get to know the big guy a little better. Activision and High Moon Studios have released a new dev diary for Transformers: Fall of Cybertron, featuring Peter Cullen, who's been the voice of Optimus since the beginning.

It's definitely interesting to get the voice actor's perspective on the game, especially considering how long he's been doing Optimus Prime.
