<step zero>
Mr. Bergmeister can be defeated with the help of either Officer Effiong or your landlord, Kurt, if the tracker in his cybernetics has been disabled.

<step one>
Talk with AIKO about defeating Bergmeister. She will tell you that the manager and Kurt have shared military experience and that he may be of use in defeating Bergmeister. Alternatively, she recommends speaking with Officer Effiong at the Gym.
<Effiong Route>
Meet with Officer Effiong at the gym and talk with her about her thoughts on her boss. After exhausting her dialogue options, she will agree to help you. She promises to contact you with a plan of attack in the future.Â
<Effiong Route cont.>
While leaving work after talking to Effiong about pitting Bergmeister and Mr. Pawn against each other, she will corner you in the elevator to 'borrow' you for the evening. She will take you to the parking garage. After a tense conversation, you will be given three choices to determine Bergmeister's fate. No matter which you choose, the questline will end.
<Kurt Route>
Meet with Kurt at Cafe Newtype after removing his trackers. He will talk to you about his time in the military and give you a memory chip that can be used for blackmail. You're going to need to find a time to talk to Bergmeister without raising suspicion; thankfully, the Thursday parties will do nicely (these will become available again after you have rescued Mrs. Antlers from her brainwashing).
<Kurt Route cont.>
Meet with Bergmeister at the party and show him the chip Kurt gave you. No matter what option you take, he will get the idea. Continue the night as normal and leave the party.
<Kurt Route cont.>
Later, you will get a phone call from Bergmeister demanding a midnight meet-up at the construction site. You will contact Kurt who will agree to pick you up and join you for the meet. After a decisive ass-kicking and some reckless driving, you will be given three choices to determine Bergmeister's fate. No matter which you choose, the questline will end.
