The intention of a public test server is for the public to test things — it’s literally in the server’s name. One Redditor, however, has taken the latest PTS build of The Division 2 and returned with a whole lot more than just the newest build’s features.
Among these items are a variety of story details for seasons two, three, and four, as well as seasonal manhunt targets, which we’ll not spoil for you here (and are hidden behind spoiler tags in the source link). What we can more openly talk about are some audio files that seem to be tasking players with securing a skyscraper floor by floor, with some floors operating as safe zones for players to pick up their progress. This “skyscraper mode” sounds fairly similar to the Survival mode of the original title’s Underground expansion.
We can confidently discuss this mode by virtue of the fact that one of the game devs has effectively confirmed that this new mode is in the works:
“We are indeed working on more content outside of upcoming Seasons and that one of the current ideas is to add a PVE mode that is meant to scratch the replayability itch. This is still in the early stages of development and is not set for release soon. In addition, while we understand the comparisons that are being made to Underground, we want to clarify that we don’t inten[d] to simply copy game modes from the first game, and that this new mode will not be ‘Underground 2.0’ and will have a unique and new take on the topic.”
