In Uncharted 3, Drake's outward appearance is fairly generic, consisting of a simple white shirt and blue jeans and a gun holster on his back in the first game, and a brown henley in the second. He was deliberately costumed in a simple shirt and jeans to provide a blank slate on which the everyman persona could be imposed. The programmers designed a layered-animation system to make Drake's motions realistic by blending multiple poses and reactions together. This allowed a complex facial and wrinkle mapping system, which provided Drake more human emotional reactions. Drake's physique is fairly fit, but not overly muscular. Drake's appearance underwent minor changes in Uncharted 2: Among Thieves. Hennig stated that Drake was skinnier than intended in the first game, and thus the designers bulked him up for the second.
