One of the twelve Stages found within Injustice 2 is Metropolis. This was once (and still sort of is) the place on earth that Superman called home, at least until his regime fell and he was place in prison for his tyranny. However, even after all the destruction that was caused by the Man of Steel in the events that preceded, this city is still buzzing with daily activity as they continue to rebuild from the prior destruction. At least, until Brainiac decides to show up in search of Krytonian Hero. Outside of Gotham and a few other stages, Metropolis is the only real city environment that can be played in.
