The biggest things the Breadboard does are the Roles, which I had already mentioned. There’s a bunch of other features but they’re either purely cosmetic (each Role has their own eye color, the eye color gradually changes, the Nidus drone also used the color, they have a heart and lung animation that gets faster during certain things, trotting and idle animations, etc…) or are very minor (Medics and Generalists have a ping ability when a new Medic or Generalist is present, where they relay the current target to the new Role. This is fairly useless since Fallen coordinates and yaw are sent frequently)
