Part 12 of the Deus Ex walkthrough: Explore Castle Clinton, disable security, find hidden items like Augmentation Canisters, and deal with NSF threats.
Walkthrough
- 1In the shanty town, find the black box next to the soda machine in the Northwest corner. It has a 20% Strength Lock. Use one or two Lockpicks to open it, revealing the code 9183.
- 2Northeast of Josh's location, find a large memorial statue. A ZYME VIAL is on top. This vial can be sold later for 65 credits.
- 3Return to the soda machine and proceed forward. On a table, find a MULTITOOL and two FLARES. Beneath the table is a BIOELECTRIC CELL. In the water nearby is 10MM AMMO.
- 4Go down the stairs. Turn right and pick up the PROD CHARGER, then enter the ventilation.
- 5Disable the NSF terrorist guarding the ventilation area and avoid the camera. Wait for the guard to move or use a tranquilizer dart. Be mindful of the noisy metal floor.
- 6Descend the ladder in the ventilation shaft. Turn right (North) and crawl. Avoid the patrolling NSF pyro with a Flamethrower and the camera. If the pyro is far enough South, you can use a Tranq Dart to prevent him from sounding the alarm. You can pick up the Flamethrower if desired.
- 7With your back to the grate and water to your left, proceed down the hallway. To your left, find a MULTITOOL. On a table, find 7.62x51MM AMMO.
- 8Around the next corner to your left, an NSF patrol must be neutralized before they can sound the alarm. Use the Riot Prod or a lethal takedown to acquire the CASTLE CLINTON SAFE NANOKEY.
- 9In the next room, a camera is present. Sprint towards the stairs to avoid the turret. Open the door and find the lower door. Bypass this 20% Strength Lock door with Lockpicks or the GEP gun.
- 10Entering Castle Clinton's Control Room grants 65 SP AREA LOCATION BONUS.
- 11If you used the GEP gun, the safe will be blown open. Otherwise, use the Nanokey obtained from the NSF patrol. Inside the safe, find a TORSO1 AUGMENTATION CANISTER, a DataCube, ROCKETS, a MEDKIT, and a NAPALM CANISTER. You also find the KIOSK DOOR NANOKEY.
- 12Use the Security Terminal to disable all security beneath Castle Clinton. You can disable cameras, or if you have high Computer skill, turn off turrets or set them against enemies. The login for both the computer and security terminal is NSF/RIGHTEOUS.
- 13Return to the room you sprinted across. If security is disabled, open the crates to find 10MM AMMO, a MEDKIT, and ROCKETS. Find 100 CREDITS on a ledge and a BIOELECTRIC CELL on top of a container.
- 14In the room to the South, find the Ambrosia Canister to gain 150 SP ACCOMPLISHMENT BONUS - Locate Ambrosia.
- 15Exit into the courtyard. Go up one level, turn right twice to find the stairs going up. You will find a red button.
- 16Alex will contact you. Ignore the keypad that opens the hatch you just came from. Use the Keyring with the Kiosk Nanokey to open one of the doors. Remain crouched as NSF are present.
- 17If you approach Billy the Kid unarmed, he will ask for food. Feed him a Candy Bar or Soy Food to gain 50 SP - Feed Billy.
- 18The nearby crate has a 20% Strength Lock and contains a BIOELECTRIC CELL.
