Rupert Zideck

Rupert Zideck is the agent of actress or prostitute Serena, and works in some way or other with the U.S Military.

In-game
He is first seen during the mission Infection, when Nate is taken to a field hospital after being knocked out by an artillery shell. Zideck is arguing with Serena about her wanting to use a gun, insisting that "this isn't a game." She replies by insulting his courage and calling him "candy-ass." During the NVA attacks on the hospital, Zideck is seen cowering in a corner, not doing anything to help in the battle. When the station is finally overrun, he is the first one to leave, running as fast as he can away from the combat.

Zideck is seen again when Nate is being taken upriver to a mansion where U.S special forces are holding his brother. As soon as the boat docks, Zideck leaves Nate behind, disappearing into the jungle. A while later, he is seen again in a boat outside the mansion, calling to Nate to escape before it is too late. The pair make their way further along the river, pursued by VC units and Infected. They finally reach a U.S unit, but as soon as the sounds of the approaching enemy become louder Zideck takes off into the jungle again, leaving the others to fend for themselves.

The last encounter with Zideck is during the level Trip. Nate sees him inside a temple, once again shouting that they should try to escape. However, it seems that his luck has finally run out, as at the moment he finishes calling to Nate an Infected grabs hold of his legs, pulling Zideck through a tunnel and throwing him off a rock ledge. Other infected then proceed to tear him apart.

 * The only time he ever fires a weapon in-game is during his escape by boat from the colonial mansion.
