This is for missions in any city, anywhere in the world.
For example New York City, Los Angeles, Sydney, London...etc.

and if you were wondering...here's New York!

Anywhere not a city but not quite the country -the suburbs-

The wide open spaces. The forests, hills valleys and anywhere rural.

Genosha, an island near Madagascar and a long-time apartheid regime against mutants. Given control by the U.N. to Magneto for some time.

The magikal relm Limbo, where Colossus' younger sister ruled for a time. This world is completely real and yet totally unreal - the manipulations of magicks herin can tear asunder all that you know....beware!!!

Anywhere "off~world" not in another dimension or on Asteroid M... you know, out there.

Anywhere not of the same dimension as our original world...looking similar or not it's not home- to be sure!
