A buddy of mine, Benny, had me to create a broken up head model for the headshot moments in Brothers in arms: Hell's Highway.
This is the first version of that model.
After going a little overboard on the headshots, I was held back a little and created this next version of the headshot.
This is the final version of the headshot that was used in the game. These images are just a basic render out of 3ds max.

I created the headshot shader in Unreal 3 as well as tweaked the severed limb shaders for the characters.
