I really liked how Portal justified the Player being able to tank multiple gunshots from the Turrets. Rather then never explaining it or just saying "its because shes super strong" they instead go for a more mechanical explanation by saying the bullets use the entire casing.

@dspike90 @PBValve That's how you get the entire bullet

@dspike90 @PBValve it's just a spicy nerf gun at that point then
