Executive Audio Director Steve Szczepkowski narrates the video, showing off Adam Jensen arriving at a train station in Praha. From there on he partakes in a conversation with a woman in the train station, discussing the corruption in the agency and the oppressive environment they are surrounded by. 

Judging from the in-game footage, which is only in its alpha stage, the game looks great, and Steve Szczepkowski does comment on the combat perspective of the gameplay saying:

If Mankind Divided plays anything like the last installment, critics should be jumping all over the Deus Ex series once again.

[By the way, there is a spoiler scene from 18:25 to 22:20, so skip past that if you don’t want to see any spoilers before you play the game.]
