Part 102

Head North to find a Repair Bot and a door labeled UC Control. Break it open using a 90% Strength (Str) Lock, a 90% Str Keypad, or a Dragon's Tooth slice to turn on the Emergency Containment. This will block the UC that produces creatures.

Southeast of the UC Control room, locate a Terminal. Hacking it will unleash a friendly Security Bot to assist with enemies.

Find the stairs to the Southeast and go up one level.

Upstairs, find another Repair Bot. Nearby, there is a cabinet with a 60% Str Lock that can be destroyed. Inside, you will find a REBREATHER, a clip of 7.62x51MM AMMO, 10MM AMMO, and a MEDKIT, along with a DataCube containing a blueprint.

Around the corner, near a radioactive barrel, find a cabinet containing a BIOELECTRIC CELL, two FLARES, and a DataCube with the coolant system code: 2242.

The chest with a 60% Str Lock, which can also be sliced open with Combat Strength, contains a NAPALM CANISTER, a PLASMA CLIP, and a RECOIL WEAPON MODIFICATION, the final weapon modification in Deus Ex Remastered.

Head East and ascend to the next level. It is advisable to activate a Hazmat Suit here; combined with Environmental Resistance, it will grant immunity to leaking nuclear apparatus.

In the Southeast corner, find the third blue-fusion reactor, code 7243. Beneath it are TECH GOGGLES. Exit North.

On this level, Grays patrol near the final blue-fusion reactor (7243). Your Hazmat Suit offers protection, and Cloaking is effective.

Immediately past the door, you can find crates with TRANQUILIZER DARTS and BUCKSHOT SHELLS.

Head North until you can turn West to find the final blue-fusion reactor.

Return to the infusion control room on the upper level. To the far West, you can find a UC that spawns Grays and its UC Control room. Another Security Bot system can be hacked to unleash a friendly Security Bot.

To the Southwest, find crates with 10MM AMMO and 7.62x51MM AMMO. If you shut down the UC on the floor below, you can eliminate any remaining creatures.

Return to the Radioactive room and descend the two stairs.

Find the elevator Switch in the Southeast corner and summon the elevator. Ride it up to the upper level.

Head Northwest, past Page, into the Northern pathway. You will find another UC Control room that can shut down the UC to the West, which spawns small Arcbots. Disabling Arcbots with a Spy Drone or EMP Grenade prevents them from respawning.

Head East at the juncture. Around the corner is the Aquinas Router, relevant only for the Helios ending.

To the West, find the Infusion Control system. Press the Switch to kill Page and end the game, leading to the Illuminati ending.

For the Helios ending: Deactivate the uplink locks on the Aquinas Router at the east end of Sector 4. This allows Helios to exchange information with your augmentations (HUD (heads-up display — the on-screen icons showing health, ammo and the minimap) - Heads-Up Display).

To initiate the Helios ending, head East to the Aquinas Router. Stand close to the door for Helios to contact you. You can bypass the 90% Str Keypad to enter the Aquinas Router door now, or proceed to the Aquinas Substation to open it.
