Deus Ex Mankind Divided - Express Elevator to Hell, Going Down Trophy / Achievement Guide - Land an Icarus Landing & Strike on foes and clear out the pack with the Typhoon. [Bronze / 15G]

You can do this in the open world anytime after "Main Mission 3: Getting in Top Shape Again" (where you fix your augmentations). I did it in a gangster hideout near Adam's Apartment. Places with enemies are marked in red on the map.
First you need to fully upgrade the augmentations "Icarus Landing" and "Typhoon". This will cost you 4 Praxis Kits - you'll get more than enough after mission 3. Create a manual save game before doing this, so you can retry if something goes wrong (and reload it later to get your praxis kits back).

Basically, what you'll want to do is go up a tall building and drop down onto an enemy. Hold circle (PS4) / B (XB1) while you drop down to activates the Icarus Strike. Then follow up with the Typhoon to defeat another enemy. You are allowed to walk around after the Icarus Strike to get near another enemy. The typhoon only hits enemies in close range.

Keep in mind you must attack enemies for it to count (civilians and policemen don't work).
