The Division has been out long enough that most players have, by now, reached the endgame. And there is a lot to do in the endgame, sure, but after almost a month of playing it, the most dedicated players have probably seen all that there is to see. This probably explains why so many of them are trying to find evidence of more end game content coming.
YouTuber King Gothalion spent quite a lot of time in the north-western edges of the map near the Dante’s Run safe-house, and he managed to glitch himself into a new, pretty much completed area- an area that contains a massive battleship in the background. This area could in fact represent the location of an all new Raid for The Division– maybe even the site for a multi group one.
We already know Ubisoft are working on getting some additional end game content out the door as soon as possible, so we might even see this new raid, or this new area, at any rate, relatively soon. I’m pretty sure it will be the most exciting bit of end game content for The Division yet.
