Nate Walker

Pvt. Nathaniel "Nate" Walker is the playable character and main protagonist in Shellshock 2: Blood Trails.

In-Game
Nate grew up in the shadow of his older brother, Cal, and was constantly made to look up to him. He was drafted in 1969 and sent to the American base in Pleiku in order to gather information from his infected brother.

Throughout the game Nate appears to be a quiet, kind hearted sort of person. He risks his own life in the search for his brother, and seems somewhat surprised by the other soldier's callousness to bloodshed. An example of this is when Sgt. Jack Griffin fires at an unarmed Cal as he is attempting to escape over a fence. Nate is astonished, but Griffin simply replies that he "tried to stop him. And I'll keep trying until I do!"

Nate survives waves of Infected and hostile Vietnamese as he tracks down his brother, aided by strange visions in which he sees though Cal's own eyes. It is unknown whether this is because Nate has protracted some of the infection, or if the blood relationship between the two acts as a psychic connection.

At the end of the game, Nate is given the option to either kill his brother and take Dr.Pierre DuMont with him, or leave WhiteKnight and save his kin. If the second option is chosen, Nate and Cal board a helicopter and fly to safety as DuMont is killed by Infected. Nate's voice then comes in to say that Cal later died, and the infection spread all across the continent. If Nate kills Cal, however, he acknowledges the fact that it was a necessary sacrifice, and swears to hunt down DuMont once he has delivered the antidote. It is unknown whether he succeeded.

The actor Tim Davenport played Nate Walker.
