City of Walkways 1
i
This level did get some significant changes in the way of layout.  There also might have only been one City of Walkways mission, which might explain the unimaginative names.

The car was changed a whole lot.  It went from being a sky blue to silver, and from a convertible to a hard top.  The wheels were changed, the body was changed, so basically, they totally redid the car.  And also, in this room, there is no light hanging above the car.  Sorry I couldn't get Christmas Jones out of the way for this picture...

This area got changed a lot.  First, there are no guys that have 7.62mm ammo there.  And the only guys that even carry that size bullet and Valentin's friends, and there are none to be found in this part of the level.  And look at the right side of the picture, in the middle.  You could go under the building there in the beta picture.  It is just walled off in the final picture.

This area isn't changed a whole lot, but the question is, what the heck is Bond standing on!?  In the beta picture on the left, he is clearly in the air, standing on something.  But in the final version picture, there is absolutely nothing there that he could stand on!  Did a pipe run through there, that you could walk on?  Was there a boat there?  Who knows.
