Tom Clancy's The Division Expansion I: Underground Released on PS4

Underground is available with the Season Pass or can be purchased separately
Ubisoft has announced that the Underground expansion for Tom Clancy's The Division, previously released on Xbox One and Windows PC, is also available now on PlayStation 4. Underground is the first of three paid expansions bringing new activities, features and items to build upon the original gameplay experience after the main story is completed.
In the Underground expansion, agents will confront and fight the threat rampaging through New York's treacherous and claustrophobic underground. Players will hunt deadly enemies with up to three friends through an endless maze of tunnels and subways.
