The color of the red areas of the suit and the glowing bits can be customized in multiplayer. These colors then carry over to any vehicle or mech you commandeer. Originally the player's name was going to go on the chest plate and the back plate as seen in the concept. This was deemed too much work for the benefit and was dropped.
The rendered image below was chosen to be included in the "Into the Pixel" Exhibition at E3 this year.
The model is around 7000 polys with 2 512s and a 128 with normal, spec and reflection maps. The readout on his visor animates.
I'll try to get some in game shots, a shot of his back and wires shortly [more like tomorrow].
Thanks,
Josh
