Harley Filben

Harley Filben is a street informant that JC Denton encounters periodically in New York.

Biography
During the NSF raid on Liberty Island, Harley Filben was brought to the north docks with the help of a drifter woman to serve as an informant for UNATCO on NSF activity on the island. Afterwards, Filben relocated to the subway station at Battery Park and later to the Underworld Tavern in Hell's Kitchen.

When JC returned to Hell's Kitchen from Hong Kong to find Stanton Dowd, JC learned that Filben was an aide to Dowd and might know how to contact Dowd. At the Underworld Tavern, Filben revealed to JC that he was working for the NSF all along, as well as for the Illuminati. Filben agreed to contact Dowd and arranged a meeting between JC and Dowd at the ruins of the Osgood and Sons storefront. Filben also revealed to JC that the Midnight Sun reporter Joe Greene is actually a UNATCO informant.

Interactions
Harley Filben can be encountered four times during the course of the game. However, only the fourth encounter is required.

Liberty Island (1st Mission)

 * Filben is found on the north dock of Liberty Island and will pass information to JC regarding NSF activity on the island if given the password "Iron and Copper." Filben will also provide the key to enter the front doorway to the Statue complex, if JC promises that the NSF commander, Leo Gold, will be left alive.
 * Meeting Filben is a secondary objective. Completing the primary objective before meeting him will result in a different set of dialogue when he is then encountered. He will then tell JC, "Why the hell'd I come here if no one needs my help?", to which JC will reply, "I found a back way into the Statue, but I'm sure UNATCO appreciates your dedication."
 * Due to how his barks work, visiting him again after completing the mission will result in additional lines depending on JC's initial answer and Leo Gold's fate.

Second visit to Battery Park (3rd Mission)

 * JC Denton can encounter Filben a second time in the Battery Park subway station. Here, if JC does not have the password needed to obtain the code to the phone booth, Filben will sell the password to JC for 500 credits (1000 if Leo Gold was killed).
 * Filben will say that UNATCO is likely targeting Juan Lebedev, who owns a terminal at LaGuardia Airport. Filben will also tell JC that the NSF has "some of your buddies at UNATCO" on their payroll, but will not mention who specifically.

Second visit to Hell's Kitchen (4rd Mission)

 * During the second visit to Hell's Kitchen, Filben can be found in the Underworld Tavern. He will say that UNATCO is about to raid the area.

Third visit to Hell's Kitchen (7th Mission)

 * When JC is is tasked with finding Stanton Dowd, he is told that Filben is an aide to Dowd and might know how to contact him. Filben is once again found in the Underworld Tavern. He reveals that he was working with the NSF all along, and confirms that he also works for the Illuminati.
 * Speaking to Filben is required for mission progression and will initiate the secondary goal of killing Joe Greene. If JC kills Greene and reports back to Filben, Filben will say, "Man, you really did change sides. Never would've thought it possible."
 * If Filben was never previously encountered, the initial dialogue with Filben will be different. He will know who JC is and tell JC, "I'm an agent myself, a double-agent... I report to the NSF and the Illuminati."

Quotes

 * "Don't take weapons into the Lady. That makes you as bad as UNATCO." (Filben recounting what he told to Leo Gold)
 * "You're a man of your word. I like that."
 * "How'm I supposed to get back to the city? Swim?"
 * "Ah-ha-ha. You can't afford that one."

Trivia

 * Prerelease design document v13.12 includes the following description of Filben: "...he’s an Illuminati assassin, working for Stanton Dowd, pretending to be a UNATCO stoolie by pretending to be a drunken bum. Filben appears over and over again to provide information, assist the player and generally confound expectations." His general character concept of being an out-of-place informant was largely maintained in the final game. However, the aspect of being an assassin does not explicitly appear in the final game.
 * Although Harley Filben is invincible throughout the game, game data associated with the cut character Thomas Dieter imply that he was originally designed to be killable, either offscreen or by the player directly. Design document v13.12 states that "if Denton rats on him, he will find Filben DOA on subsequent missions."
