Walkthrough - Laboratory

Welcome to the heart of Umbrella's dark research. The Laboratory is a dangerous, multi-layered area filled with advanced B.O.W.s and environmental hazards. Precision and resource management are key to survival here. Be prepared for tight corridors and unexpected encounters.

Entering the Laboratory

After activating the main elevator in the Guardhouse, you'll descend into the Laboratory. The first area you enter is the Main Corridor (B1). Immediately to your left, you'll find a save room. Use it!

  • Save Room (B1):
    • Items: Ink Ribbon (on the table), First Aid Spray (on the shelf).
    • Action: Save your game. Organize your inventory. You'll want a strong weapon, plenty of ammo, and at least one healing item.
  • Main Corridor (B1):
    • Exit the save room and proceed down the corridor. You'll encounter a few Zombies. Conserve ammo by using your combat knife if you're confident, or headshots with your handgun.
    • At the end of the corridor, you'll see a door leading to the Generator Room.

Restoring Power

The Laboratory is partially powered down. Your first objective is to restore full power to access critical areas.

  • Generator Room (B1):
    • Upon entering, you'll find a large generator. Interact with the control panel.
    • Puzzle: You need to activate the generator. The sequence is usually indicated by a blinking light or a subtle audio cue. If you fail, a Hunter may drop from the ceiling, so be ready! The correct sequence is generally Up, Up, Down, Up (this can vary slightly between playthroughs, so pay attention to visual cues).
    • Once activated, the lights will fully come on, and you'll hear a distinct hum.
    • Item: Check the small desk near the entrance for Handgun Ammo.
  • Back to Main Corridor (B1):
    • As you exit the Generator Room, be wary! The restored power often triggers new enemy spawns. A Hunter or two might be waiting for you. Use your shotgun or magnum for these creatures. Aim for the head or a quick two-shot body kill.
    • Proceed to the double doors at the far end of the corridor, which are now powered.

The B2 Level and V-ACT

The double doors lead to a staircase descending to B2. This level introduces a new, more aggressive threat.

  • Stairwell (B1 to B2):
    • Descend the stairs. You'll hear unsettling noises.
    • Item: Halfway down, on a small ledge, you can find Shotgun Shells.
  • Main Corridor (B2):
    • This corridor is darker and more claustrophobic. You'll immediately encounter V-ACT Zombies (Crimson Heads). These are faster, more resilient, and have a devastating lunge attack.
    • Strategy: Do NOT try to run past them unless you are extremely low on health/ammo and know the path perfectly. Engage them with powerful weapons like the Shotgun or Magnum. Aim for the head to stun, then follow up with more shots. If you have a Grenade Launcher, Flame Rounds are highly effective.
    • There are two doors here: one to the left (Observation Room) and one straight ahead (Research Lab A).

Observation Room and Keycard

The Observation Room holds a critical item for progression.

  • Observation Room (B2):
    • Enter the door on the left in the B2 Main Corridor.
    • Inside, you'll find a console and a large glass pane looking into a research area.
    • Item: On the console, you'll find the MO Disk (or Lab Keycard depending on your character/version). This is essential for accessing further areas.
    • Encounter: As you pick up the item, a Hunter may burst through the glass or drop from the ceiling. Be prepared for an immediate fight.
    • Item: Check the small cabinet for Magnum Rounds if you have the Magnum.

Research Lab A and the Fuel Supply

With the keycard in hand, you can now access Research Lab A.

  • Research Lab A (B2):
    • Use the MO Disk/Lab Keycard on the door straight ahead in the B2 Main Corridor.
    • This room contains several research stations and a large tank.
    • Item: On one of the tables, you'll find a Fuel Supply Capsule. This is crucial for the next puzzle.
    • File: Look for the Researcher's Will file on a desk, which provides some lore and hints.
    • Encounter: Expect a few Zombies or even a Hunter to be lurking here. Clear them out to safely retrieve the item.

The Incinerator Room and Activation

The Fuel Supply Capsule is used in the Incinerator Room to activate a critical mechanism.

  • Incinerator Room (B2):
    • From Research Lab A, head back to the B2 Main Corridor and take the other path, which leads to another set of doors.
    • This room is characterized by a large incinerator unit.
    • Action: Insert the Fuel Supply Capsule into the designated slot on the incinerator control panel.
    • Puzzle: You'll need to activate the incinerator. The controls usually involve setting a temperature or pressure. The correct combination will cause the incinerator to roar to life, opening a hidden passage.
    • Hidden Passage: Once activated, a section of the wall will retract, revealing a ladder leading down to B3.

Proceed down the ladder to the next level of the Laboratory. Be ready, as the deepest parts of the lab hold the greatest horrors.
