Frankenfurter makes an appearance during Operation: Hollywood and Vain. He is one of the three Hollywood action hero parodies to make appearance in the game and can be controlled by the player to make a stand against Yuri's occupation.
He is armed with a minigun, able to take on infantry and vehicles easily and to an extent, buildings and structures. Despite this, it would not be advised to use him to take on large groups of gattling tanks or garrisoned buildings. Frankenfurter's immunity to mind control makes him useful for combating Yuri clones.
Note: in patch 1.001, Arnnie Frankenfurter uses the voice set of a GI.
For unknown reasons, Arnnie and the other action hero parodies have had their unique dialogue and names replaced by patch 1.001, with all of their quotes replaced by standard GI ones. In this version, Arnnie is called simply Hero. The original strings and audio files are still found in the game files.
His secondary death animation uncovers a T-800 skeleton underneath his skin.
