Added a little bit more of a Metropolis-y flourish to the mostly Rooftop Run dominated bassline, removed a few of the guitar riffs because I thought I overused them, and added a few more bars of bassline before the bridge near the end.

Copied from the v1 blurb:

"Funnily enough, Metropolis Zone and Rooftop Run Classic have the same chord progression - I-II-IV-I (which it turns out, thanks to a quick bit of research, has its first known use in the Beatles' "Eight Days a Week". So a fairly recent development).  It seemed like a nice opportunity to try and mix them together into something.  Different parts of each melody line have been played around with to try and fit the tunes into each others backing.

"Hopefully it works out all right.  It feels a little slow maybe - Rooftop Run got to pick the key (A Maj vs. Metropolis' C Maj), so it's only fair that Metropolis got to set the tempo.  Let's call it mellow. Yeah. Mellow."
