This is the fully armored version of the Sintek grunt.
The armor shows some of the details of the uniform underneath (the game includes a difficulty system that will add armor to a character depending on your abilities as a player).
The proportions are off due to the fact that it is to be modeled on a HL2 skeleton (shorter legs, long arms), which made it a bit more challenging to make him look heroic.
I added flashing lights on the shoulder pads to show that the Sintek grunt is primarily a police force (controlled by the evil Elexis).
In the rendering I tried to show the color spec as well as texture and reflectivity.
