If you have The Division for Xbox One or PC, you can access the game's first paid expansion, Underground, today. But how to find it? First, you need to have own it, of course. It costs $US15 ($20) (and won't be out for PS4 for about a month, such are the ways of platform exclusivity deals). The folks running the game's official Twitter account also advise people who have the game's Season Pass to ensure that they actually own the DLC by going to the online store and requesting a download. The expansion should show up as owned or free.
You'd think you'd then be able to jump into the game, head to the new entrance for the Underground that has been added to the game's HQ and get going, right? Nope!
First, you need to find the Secure Quarantine Sector mission.
You'll be fighting some level 30 enemies. At least that's who spawned for me. Do that mission.
Then go back to your HQ. Go to the back, near the rewards vendor and you'll see a new doorway:
Head on through there and you'll be in the new Terminal social space. The entrance to the Underground will now be open. Head down there and you'll wind up in this new spot:
You'll get prompts that will take you through your first actual Underground operation, and then you'll be free to just have at it.
Underground missions are designed for one to four players. You set a lot of the parameters of the missions yourself, including how many objectives you'll be going for and which difficulty tweaks to activate. A lot of these settings require a certain Underground rank, which you'll attain as you play more Underground missions.
These missions are all in no-respawn zones, so you need to play carefully. The reward aside from simply enjoying playing is the chance to get extra-good loot, without the fear of losing it that you get when grinding through the Dark Zone.
Added bonus: There are new audio logs to collect!
We've just begun playing Underground and can't yet tell if the expansion is the shot in the arm that The Division needs. We'll have impressions later this week.
