The GozMod is a modification for your AFM pinball machine which would have been included in the pinball machine, had the technology been available when it was originally designed. This modification replaces the PCB of the Mothership and uses bi-colour LEDs which change from green to red in accordance with the game play. The resulting modification is subtle and enhances the game play without being too brash, intrusive or "in your face".
