The Steel Spartan also features removable CQB armor new to the Halo universe - chest and shoulder plates and helmet are removable and will be interchangeable with other McFarlane Spartan figures

This is actually pretty cool because now you can change them around and mix em up. For example you could go agienst the game's color system and put a red helmet on a blue body with white shoulder pieces...or something..lol..

Thank you. Now I can die happily.

So, when you take the helmet off will you see Chief? Or will it one piece therefore the head is not visible?

It might just have it so the "head" is like a black circle that the helmet clicks onto..Im not sure..I'll find out in March 2008.
