If you pay Filben for the password you use when speaking with Curly you will earn some points for it. (A nod to Marc for finding this.)

Talk with Curly in the shanty town at Battery Park. If you got the codeword from the bum earlier in Hell's Kitchen, he'll give you the code for the phone booth and some points to go with it. (Tip 'o' the hat to Rob for the info.)

Fix the water problem for the molepeople by opening the water valves in the northeast end of the Brooklyn Bridge Station.

After fixing the water problem talk to the moleperson just south of the door you entered to reach the water valves.

Find the secret passage that leads from the Brooklyn Bridge Station to the helibase. No way of avoiding this since its the only path you can take.

Either kill Rook the drug dealer and talk to El Ray, or give a zyme vial to Larry in the men's restroom in the northwest part of the station.

In the molepeople tunnels find and talk with Kevin Bradly.

Find the secret room in the molepeople tunnels where the NSF terrorist commander is hiding.

Instead of killing the NSF terrorist commander talk with him.

Just before you reach the restrooms, look under the rubble for an armed LAM and goodies. In reaching this area you may also trigger the Progress Bonus listed below. (Conpiratorial nod to Paladin for finding this.)

Enter the men's room to proceed from the molepeople tunnels to the helibase.

After passing the two robots guard the passage you'll get this as you approach the two steel doors that lead to the helibase.

Shortly after passing through the double steel doors mentioned above, you will run right into one of the missing Ambrosia canisters.

Enter the secret room that connects off the computer room on the second floor of the helibase. The button for opening the room is behind a plant.

Find the other secret room in the helibase. Its also located on the second floor but on the opposite side of the one mentioned above. Hack the security terminal in the aforementioned computer room and open the door associated with camera one. Alternately, use the pinball machine in the room to open it.

Arrive at the airfield either by the elevator or sewer. (Thanks to Rob for the tip.)

Find the Ambrosia canister in the Boat House at the airfield.

Enter the secret room behind the staircase in the Barracks at the airfield.

Enter the passage connecting the Barracks to the hanger containg the 747 at the airfield.

Find the last canister of Ambrosia in the Cargo Bay of the 747.

Onboard the 747, instead of assassinating Lebedev, keep talking to him until Anna Navarre gets pissed.

However, if you kill Agent Navarre and Lebedev lives he'll provide more info for you and you will earn 200 points instead of 175. (A nod with dark sunglasses to Jason for the tip.)
