Gaming Boulevard reviewed The Division Underground and concluded:
Underground is more than just a DLC pack, it’s a true expansion and even demonstrates the true potential of the game. The world is well crafted and filled with details. The metro stations and tunnels all look insanely realistic and feature a certain atmosphere so you simply can’t resist moving forward. The gameplay hasn’t been innovated that much but thanks to the Directives and better weapons/gear, we know fans will have a blast playing it. The Division wasn’t perfect from the start but this first big expansion breathes new life into the game and is worth checking out.
