Brock

Brock is an explorer who found Shangri-La along with Gary, who works for him. He was trying to prove the existence of Agartha. The player must help him escape Shangri-La. Over the course of the escape, Brock recognizes that the temple wasn't made by an ancient civilization but was built by modern-era people.

Brock's voice has an uncanny resemblance to that of Dr. Maxis in Der riese radio messages. Dr. Maxis may have survived when Richtofen activated the teleporter with him, Samantha and Fluffy.

Trivia

 * According to the radio found near the MPL, Brock seemed to already know about the zombies in Shangri-La.
