The cutscene title of the Terrastore underground in Kansas City, MO is incorrect:

We read "Métro de Kansas City". In French "Métro" should be used for an underground public transportation system.
Therefore here is my suggestion:
- Souterrains de Kansas City -> "Undergrounds of K.C."
- Or, more precise, if the number of characters allow it:
Centre d’activité souterrain de Kansas City -> "Underground activity center of K.C.". Source in French: https://phototrend.fr/2015/02/subtropolis-kansas-city
Take care!
