It covered them all the world wide, though at the start they showed the new Call of Duty game and how they incorporated them in it.
They visited Activlink who have built an Aliens style power loader type item which is designed for use in eathquakes.
They also visited MIT to look at robotic hands and extra arms so you had 4 arms! That was clever, it was worn on the back and it followed your arms, so when trying to put up a roof panel the other two arms sensed what you were doing and held up the panel from behind your head as you attached it with your arms.
They visited Decca in the US to see their arms
They covered gloves that would increase force you applied in your fingers and legs
They also covered walking suits from exobionics
The Zion D3o suit is amazing its a flexible foam that becomes solid if hit.
