Every time I play solo I try to kill george as many times so I can get the Wunderwaffe and the perks. As I was killing I noticed that George actually does show signs of his damage in stages. All of the stages are shown on the light that he carries. His first stage of damage is his blue light will shoot off sparks. This shows you have damaged him and by this time you have probly wasted a scavenger clip. The second stage of the light is a blue light that occasionally switches to a red light. The final stage is his light will show up completely red. This tells you that George is ready to DROP!
Enjoy tracking the damage you've dealt on George.
