How to unlock the Acrobat achievement in Dishonored 2 - Definitive Guide
You can do this very easily in Mission 01: A Long Day in Dunwall with Ramsey. As Ramsey finishes his conversation and climbs up the stairs, you can crouch on the upper railings and drop assassinate him. You can do this 10 times by saving before dropping on Ramsey and then reloading after performing the execution. Unlike D1, save scumming works like a charm.
Note to bear in mind; I could not get this to unlock with drop takedowns, the non-lethal variant, and so I believe you must specifically assassinate. I know it says assassinate in the achievement description, but I was kind of hoping the non lethal variants would count.
This achievement can be earned at any time during your playthrough, specifically on the lethal High Chaos run.
You will be introduced to Drop Assassinations fairly early on in the game during Mission 1, A Long Day in Dunwall. While perched on a ledge on any kind (rooftop, railing, etc.), you can eliminate enemies who are below you by jumping off the ledge and falling on top of them. Right before you make contact with the enemy, a quick prompt will flash on the screen: to knock out or to kill.
There are several opportunities across all nine missions in the game to get this done, but do keep in mind that you must kill the enemies rather than knocking them out. The achievement will unlock once you have performed ten successful Drop Assassinations.
Civilians in hostile territory also count.
