The new Underground mission lets players work their way through randomly generated 'dungeons'.
The expansion, which is due on June 25 for Xbox One and PC and August 2 on PS4, lets you battle the Cleaners underneath Hell's Kitchen in areas that generate randomly.
Our friend Arekkz went hands-on with the new expansion at E3 and has uploaded a video, highlighting the tense team-based gameplay The Division fans know and love.
Speaking as a lapsed Division player, it looks pretty fun.
You'll be able to play through these operations in the game's new Heroic difficulty mode as well.
