Laboratory & Neo Ark

• Swipe the Bowman Card (or Yoshida Card) in the B2 elevator hallway reader to enter the operating theater.
• Climb into the upper laboratory: you will find an item chest, a telephone save point, and the Central Mainframe Computer.
• Access the terminal and enter the password:

A3EILM2S2Y

• Select the 4th menu option to answer three randomized security questions:
  • Desert where facility is located: Mojave
  • Theory of human origins in Africa: Mitochondria Eve
  • Agency supervising MIST: FBI
  • Product of mitochondria combining glucose and oxygen: ATP
  • Organism possessing mitochondria: Crustaceans
  • Manhattan incident culprit: H. Klaup
  • Victim causing the N.Y. outbreak: Melissa Pierce
  • Town near Nevada facility: Dryfield
  • Organelle containing DNA: Mitochondria
  • Mitochondrial gene transmission: Maternal
• After reviewing the files, the phone rings. Proceed to Pod Gantry Service on B1, enter the control room, and cycle through all camera feeds to unlock Neo Ark, disable automated security turrets, and power up the B2 elevators.

• Descend to B2 and ride the express elevator into the massive underground biosphere of Neo Ark.
• Exit the observatory south toward the Shrine structure.
• In the puzzle chamber, inspect the 4x4 hieroglyphic tile board. Every valid solution leaves the bottom-right slot empty, and each color arranges independently:
  • Red (4 tiles, required): arrange them diagonally, from the bottom-left corner to the top-right corner. Unlocks the rear doorway to the Alpha Generator.
  • Blue (3 tiles, optional): line them up along the top row. A sarcophagus slides out of the wall with an MP Boost2 inside.
  • Yellow (4 tiles, optional): line them up along the left column. Triggers a Black Beetle ambush — no item reward, just a fight.
• Solve the red arrangement to progress. The blue and yellow puzzles are optional and become inaccessible once you defeat the Alpha Generator, so solve them first if you want the MP Boost2.

Expand

• Step through into the energy chamber and locate the Alpha Generator:
  • Attention!: Destroy the wall power console first before attacking the beast itself.
  • Destroy the generator monster to sever the biosphere's first primary power feed.

Expand

• Return to the central observatory and take the northern path into the dense forest dome.

• Ascend the Pyramid of Tlaloc and step onto the four colored step switches:

  • Press in this order:

  BLUE x6, WHITE x2, RED x3, YELLOW x5
  

  • A lever will emerge beneath the Tlaloc statue: pull it.

• Advance through the submarine tunnel toward the central island. Pick up a Lipstick concealed in the lower shrubs and descend into the well:

Giant Diver (Well Amphibian)

Difficulty

An electrified amphibious predator guarding the underwater basin.

Expand

Attacks

• Arcing electrical homing lightning bolts
• Subaquatic ramming dive

Strategy

• Sprint in circles around the well perimeter rim to evade homing plasma discharges.
• Whenever it surfaces above the waterline, bombard it with Pyrokinesis or FireFly incendiary shotgun shells (it is exceptionally weak against Fire).
• Upon defeat, search the drained basin to retrieve the Skull Crystal relic (+25% weapon damage).

• Return to the pyramid and enter this second step combination to swing the bridge toward the Beta Generator:

  RED, YELLOW, BLUE, WHITE, BLUE, WHITE, RED, YELLOW, WHITE, BLUE, YELLOW, RED
  

• Cross the new catwalk into the beetle courtyard (collect the Neo Ark map), climb the stairs, destroy the control console, and eliminate the Beta Generator.

Expand

• With this final objective, your incursion into Neo Ark concludes. As you ride the elevator back up to the facility, you will witness an introductory cinematic for the Golems, the lethal cybernetic elite units that will dominate the final act of the game.

Expand

Expand

• With both generators offline, return to B2, save your progress, and equip the Grenade Pistol.
• As you advance down the hallway toward the living quarters, destroy the wall speakers to prevent continuous MP siphon.

Giant Bowman (Psychic Warden)

Difficulty

A high-tier telekinetic guardian guarding young Eve's residential quarters.

Expand

Attacks

• Homing psychic telekinetic sphere barrage
• Active cellular health regeneration

Strategy

• Continuously fire 40mm explosive grenades: every direct blast staggers the creature and completely cancels its health regeneration.

• Enter the bedroom: meet young Eve, take the MD Player from the dresser, and grab the Ringer's Solution from the IV stand.
• As gas floods the chamber, inspect the glass pod, then walk (do not run) toward the elevator so Eve follows closely behind.
• Witness the submarine tunnel confrontation with No.9. Return to the B1 underground parking garage.

Expand

• Call M.I.S.T. from the Pod Gantry telephone after reading Pierce's note (Mandatory for True Ending).
• At the parking crane console, press the following combinations: Red + Green + Blue for a Belt Pouch, then Blue + Yellow to lower the red sedan.
• Swipe the Bowman Card on the gate terminal to open the exterior blast door.
• Pick up Eve's Teddy Bear lying on the pavement near No.9's motorcycle.
• Defeat the 2 Golems in the control bunker, flip the switch, and exit to the surface military encampment.
