Yes, you are right, the bottom images are from the BCD demo.
But where did Agent MB get the BEL images from? I haven't seen them before, that's amazing!
Easy! I was searching some old C2 screenshots for my pre-release collection, and then I found some Beta screenshots of BEL and BCD in the 1995 to 2000 versions of Eidos and Pyro Studios websites.
And guess what, C2 was going to be released in late 1999, and not in 2000 nor 2001.
