LAMBERT – A few minutes ago, Third Echelon intercepted an encrypted communication between Jin Soo and the UN Headquarters in Manhattan. Something dirty is going on.

Lethal force is not allowed and I'll abort the mission as soon as I hear a general alarm.

Trivia[]

  • By attracting guards to the combination locks you can recognize their codes by using Sticky Camera and Thermal vision or Night vision mode. Secret code in security room is 250282.
    • The simple method is to stun the guard in room and push to another guard but in this way the stealth rating will be lowered. In any case, we already know the secret code.
