Underground depicts my experience from 2008-2010 when I began walking on crutches to hold myself up and to keep from falling. People on the street would ask me "what did you do?" and I would quip "motorcycle accident." My disease was still "underground" so to speak, but the fight against it was becoming visible. During this time frame I moved from Chicago to Phoenix in order to take an academic position and get away from danger of the ice and snow. This piece is a shooter game in which all of the "enemies" are invisible but the shooting device and ammunition are visible. There is an explosion sound when the projectiles come in contact with the enemy. This game is easy to learn and there is nothing to master. The game is experienced for the sake of the game.
