After taking enough damage to my center torso to getting cored, in the third person view of the death scene I noticed some heavy stretching on the faces of the center torso. Faces affected are the top and frontal faces of the model, the intakes for the center torso is also affected. From the 5+ I've played trying to recreate the effect, its focused on ballistic munitions such as AC and Gauss weapons. Laser weapons still work properly.
Variants I've recreated this on are the DRG-5N and -1N.
