SM02: Cult of Personality is a side mission in Deus Ex: Mankind Divided. It is available for Adam Jensen to complete during his first visit to Prague. Completing this mission unlocks the "Cult of Personality" achievement/trophy.
Enter the sewers near Zelen Apartments, go to the left, where there is a long opening in the tunnel, and left again until you reach an area that has gas coming from it. Near this is a small tunnel built into the wall. Once you go through it, continue to walk until you see a man named Viznik near a door. If the player talks to him, he will tell them he has been kicked out of the cult and he thinks there is something wrong with the cult leader. He gives Jensen a card to get through the door.
Enter the Locked Area Edit
After opening the door, a small cutscene plays which shows that a part of the sewer has been converted into a large room that acts as a mini town with several followers in the room. Richard the Great talks to Jensen through the main screen, saying how he made a safe place where good people can be free in a non-violent place. If the player tries to confront him they will be stopped mid-sentence due to Richard's influence in the room preventing anyone from disagreeing. The CASIE augmentation is rendered useless as well while under the influence and the only way to get out of the conversation is to cave in and stop resisting.
After this, Richard stops and allows Jensen to wander around as long as they do not go up to the restricted area, which is guarded by lethal turrets; rather ironic for a peaceful utopia. If you want to take a diplomatic approach, find a poster promoting a magic show, which will prompt Jensen to go visit a shop in northern Prague.
Seek Out Liborio Edit
Visit Liborio's Magia shop and tell him about Richard and his cult. Liborio is shocked to learn he is still alive and tells Jensen that they used to work together on shows in the old days, giving audiences shared fantasies with the help of hypnosis and social enhancer augmentations with pheromones, making sure to pre-screen audiences to see which minds were easier to influence. In time, however, they were forced to quit because their work was deemed too dangerous. He says that Richard may be using this technology to influence people and gives jammers to Jensen that, once all three are placed, will cut off Richard's signal.
Find a Way to Confront Richard Edit
For the quick approach, you can skip over visiting northern Prague and instead head up the ladder into the restrict area. Note that, if you do not talk to Liborio, you will not earn the achievement. If you have level 5 hacking or a multi-tool, head straight to the locked gated door. Once through, head down the tunnel to Richard's room. If you do not have the required augments or tools, you will have to head left, taking cover from 3 turrets before reaching his room (this side has a level 2 security panel). Richard can be taken out, lethally or non-lethally, but be careful as he will shoot on sight if he detects Jensen. After this, disable the breaker box in the room, shutting down the signal. The cult followers will not be under Richard's hypnotics anymore, but will be rather confused and semi-shocked at their situation.
Install the Signal Scramblers Edit
If you talked to Liborio and got the jammers, you can take a more diplomatic approach. Head upstairs and, using the barrels to block the turrets' view, place the jammers, with Richard asking what you are up to each time you place one. The first emitter is on the corner in front of the first turret (if you look at your map, it is on the corner between the first area and the small hallway if you go left). Use a barrel to make your way down the guarded hallway, dropping it occasionally to keep the second turret from going into an alarmed state. Eventually you will get close enough you can quickly move under it. You will see the second emitter right after this, on the inside part of the "L" corner. The final emitter is in the room with the third turret. Make your way behind this turret and you should see the emitter in a corner.
Reveal Richard to the Others Edit
Once all three jammers are placed, head back to the microphone to talk to Richard, who is taken aback when Jensen calls him out on his charade. Choose pity then mitigate to make Richard see the error of his ways and stop, while simultaneously letting the cult followers make sense of what transpired. This, in turn, allows Jensen to now move freely on the second floor and enter Richard's room, who is now sobbing on the couch.
