Get through the lobby | Mission 3 Dishonored 2 Guide
Last update: 24 November 2016
After arriving at the Addermire Institute equip the heart to locate the bone charm hidden underneath the rail. You can get there by jumping on top of the sewage pipe shown on the above screenshot.
If you follow the Ghost path, collect the item, head towards the stairs on the right side and crouch to avoid getting detected by a guard walking in the area. Wait for a good opportunity, approach the guard from behind and stun him. Afterwards, dispose of the body by throwing it into the bushes on the right side.
After you've dealt with the first enemy, head to the main entrance where there will be two guards talking with each other. Wait for them to split up - one of them will start patrolling the other side of the lobby entrance, whereas the other one, standing in the middle of the room, will turn his back to you. You can now use Blink or Far Reach to get to the second enemy patrolling the other side of the building and then get back to the foe located in the reception area. Afterwards, you can safely explore the reception area - you can find a document, food, bolts, potion and a coin here.
Now head towards the main lobby, until you reach the place shown on the above screenshot. The guard located on the left side can easily notice you - crouch as soon as you arrive in the area, approach the enemy from behind and get rid of him. Note that there's a second guard wandering through the corridor - wait for this foe to turn around before deciding to eliminate the first foe.
Caution! The guard patrolling the lobby might be alerted by the fact that the second guard is not standing near the railing. If that is the case, you will be forced to eliminate the guard standing near the said railing first.
After getting rid of the guard standing near the railing, head towards the right side and jump on top of the balcony shown on the above screenshot. You will notice a wall of light power supply there - take out the whale oil container from the locker to disconnect it. Doing so will also save a woman located at the bottom of the room - although she won't offer any reward or information in return. Another approach is to collect an empty bottle from the reception and throw it at the guards bullying the woman. This will not only save her, but also prevent the enemies from knocking her unconscious, allowing her to run to safely.
After you've saved the woman, get back to the main lobby and look to the left (towards the place where you've eliminated the first guard). Jump on top of the decoration shown on the above screenshot and make your way to the reception, where you will stumble upon a new guard sitting by the desk. Wait for the guards located near the wall of light to go on a patrol and get rid of the enemy.
Eliminate the last guard in the same manner and collect the bone charm from the location shown on the above screenshot. Afterwards, start exploring the now clear lobby where you can find a number of useful items. While passing through the wall of light don't forget to collect a painting located on the right side. However, before you do that, head up (to the place where you disconnected the wall of light power supply) and into a room filled with more treasures, especially a safe - it contains the first blueprint (Combat Sleep Dart), as well as coins. The combination required to open the safe can be found written on a piece of paper, lying on top of a desk located at the entrance to the room.
