Umlauts or no Umlauts

Umlauts or no Umlauts is a secret achievement/trophy in the A Criminal Past expansion for Deus Ex: Mankind Divided. It is awarded for successfully conversing with The Fixer at the end of the mission, and deciding whether he stays behind or instead accompanies Adam Jensen on his way back to TF29.

Walkthrough
To complete this achievement, The Fixer needs to survive the confrontation with Hector Guerrero at the Helipad. The easiest way to accomplish this is to select the dialogue option permitting Guerrero to kill The Fixer, and then immediately incapacitate Guerrero before he is able to actually kill The Fixer.
