Ubisoft has announced that servers for The Division will go down for maintenance this morning in preparation for the update 1.4, which is coming with a ton of changes. It's unfortunately not coming with the new DLC Survival, however, as it was delayed last August until later this year.
Server shut down starts at 9:30 am CET (8:30 am in the UK) this morning and will last for three hours. You can try to download the update in the meantime, however, and come back to matches as soon as the servers go live again.
The list of changes and improvements has been growing since Ubisoft announced the patch. There are new features, activities, loot and rewards, rebalanced weapons, gears, skills and game stats, gameplay changes, UI improvements and a lot of bug fixes too. You can check the full list over at the Ubisoft forums. This update should be big, but what features are you keeping your eye on?
