DEUS EX: Mankind Divided – Time Traveler Achievement
You managed to bring Koller the Neuroplasticity Calibrator before he even asked for it
In order to do that you have to find the device before you finish mission 3 where you visit Koller for the first time.
Travel to the North-West Metro station and find the underground casino. Otar runs this place and he has the calibrator locked away in his main room. Take out the guards there and steal it from him.
Now you can get back to Koller and surprise him with the “Time Traveler” Achievement / Trophy.
