This is part of a collaborative project I introduced to students during my time as a TA at SCAD; this doubled as a huge part of my thesis. Walking City was a tournament styled comic project, where students would introduce their own characters into the provided scenario and depict their characters surviving matches while telling their character's story.
The comic is purposely made to provide vague info to allow the competitors (the students in this case) to easily mold the story, characters, and environment to their own.
