I say “unofficial” because I noticed that the stages have background characters that can represent certain teams.
High School - Saisyu and Chizuru so it’s the Japan Team
Beach - Duck King and Alfred so that’s the Fatal Fury Team
Dojo - Butt and Eiji so that’s the Art of Fighting Team
Cambodia - Marco and Eri from Metal Slug. Since they’re military characters, I assume that this is the Ikari Warriors Team
So, what stages would you say represented which Teams?
