The complete comic, Bionic Commando: Chain of Command, is out. It's been out for a little while now as a whole over at bioniccommando.com. I'll try not to spoil it for those of you who haven't read it. So go read it for yourself right now! 

The Chain of Command takes place between the events of Bionic Commando: Rearmed, and the upcoming sequel. You'll see the events that transform the cool red haired Nathan "RAD" Spencer into the hard-edged, grungy looking war machine you've seen in the trailers. As always, Nathan is the hero, and he has the heart of a hero. Unfortunately, his conscience lands him in prison to rot.

To find out how he gets out of the confines of prison... Well, you'll just have to play the game when it comes out to find out!

Until then, go read the story! BTHR ZERO X of Capcom Unity has it up with a cover, and of course you can find it on the official Bionic Commando site.
