Walkthrough
  1. 1
    After the opening cutscene, explore Megan's office. Interact with the [EBOOK], [NEWSPAPER], [FRAMED PICTURE], [BOOK], and [TOY CAR]. Inspect Megan's emails and then talk to her.
  2. 2
    You'll find yourself in David Sarif's office. After a brief discussion, an alarm sounds. David will give you the elevator code: 0451.
  3. 3
    Head to the elevator and use the code. As you descend, Adam will draw his Combat Rifle. Check your inventory; you have a Combat Rifle, 43 bullets, a Frag Grenade, and a Concussion Grenade.
  4. 4
    Exit the elevator and move under the lab door by crouching. As you approach the glass wall, two scientists will be killed.
  5. 5
    Head left, move the metal crate away from the wall, hop onto the other crate, and open the ventilation grate to proceed.
  6. 6
    Navigate through the destroyed wall, being careful of flames. At the end of the hall with boxes and forklifts, enter the next hall and take cover behind a desk.
  7. 7
    Two adversaries will enter. You can sneak past them or engage them. If fighting, aim for headshots and use controlled bursts. Grab their weapons for ammo if needed.
  8. 8
    Hop over boxes in the next hallway and carefully open the door to the next lab. Three adversaries are present.
  9. 9
    You can use a gas canister near the door to eliminate them after they finish conversing, or sneak past.
  10. 10
    After dealing with the mercs, continue down the hall. You'll see an augmented woman kill scientists.
  11. 11
    Head through the door and crouch near the stairs. A team of four mercs will enter the hall below. Use cover and aim for headshots, or use stealth to sneak past behind the railing.
  12. 12
    Continue down the hall until the next cutscene triggers, marking the official start of the game.
