What are you all doing with the Cybermen once they've been disabled?

I slipped away from that 'UNIT'(?) member and hacked into their comms systems in order to determine that this was the place to was told that this would be a good place to get some answers.

I went from Gotham to London in the blink of an eye. I don't think that this is a kidnapping because, if it were, dumping me in the middle of a public area and abandoning me wouldn't exactly be an ideal strategic move. So what is it? What's going on here? And how is something like this even possible?
