Express Elevator to Hell, Going Down is an achievement/trophy in Deus Ex: Mankind Divided. In order to get it, you must jump down from a height and activate the Icarus Strike before hitting the ground, then immediately afterwards activate the Typhoon Explosive System. You must have both the Icarus Landing System and the Typhoon augmentations unlocked to get this achievement.
A convenient place to get this achievement is during the first mission Black Market Buy, in the atrium of the hotel. Jumping down from the top of the atrium rather than using the elevator activates the Icarus Landing System, and you can therefore use the Icarus Strike when landing. During this mission you will also automatically have the Typhoon unlocked so make sure to activate it directly after landing. It is of course possible to get it at a different point in the game, by jumping down from a height near an enemy or enemies.
Despite the description of the achievement, all enemies in the vicinity do not need to be taken out by this combination of attacks. Activating both augmentations appears to be enough.
- The title is a reference to the movie Aliens where it is a quote spoken by the character William Hudson.
