Atlantis - security office | Chapter 3 DARK Guide
Last update: 11 May 2016
Use the narrow corridors to reach the security room. Eric will make an unsuccessful attempt of contacting Rose and that's not the only problem you'll have to deal with, because four new guards will arrive in an elevator soon and of course it will make it harder to reach the exit.
Quickly take cover to the right and wait for all enemies to reach their designated posts (don't try running to the exit from the security office, because you won't make it in time and as a result you will be noticed by enemy forces). Keep using cover, waiting for the first guard to appear to your right (screen above). The best way of killing this person is to use a long-distance attack. If for some reason it's not possible then you will have to wait for the guard to turn around and quickly move closer to him to perform a standard execution.
Head over to your right, avoiding the main part of the security room for the time being. Make sure to keep checking your surroundings here, because you'll find a PDA (200 experience points) along the way (screen).
The next person you should take special interest in is the guard seen on screen 1. Wait for this person to turn around and to move closer to one of the computer terminals. You can now either use one of your vampiric powers to kill the guard from a distance or activate Shadow Leap to avoid a metal detector in order to get enough for a standard kill (screen 2).
Avoid the metal detector for the second time and return to the main part of the security room. One of your enemies is standing here and you should eliminate him.
The last guard is stationed close to the exit from the security office. Just as before you should consider using Shadow Kill or Shadow Grip to eliminate this person from a distance. If you want to do a standard kill then use Shadow Leap, but make sure to choose a destination for your teleportation as far away from your target as possible.
Your current destination can be seen on the screen above and it's an exit from the security office. Important - If you don't want to kill anyone in this location then you must rely heavily on teleportation, pay special attention to two of the guards who are constantly moving and avoid stepping through metal detectors.
