The Public Test Server, which will allow gamers to test updates and DLC before they get released, has gone live for The Division players on PC. The server will be active so long as there is something to test, then it will go dormant until the next update or DLC is ready to be tested. For a full breakdown, check out this statement from Ubisoft:
“On the PTS, you will be able to test the current build for Update 1.4 before its official release on the live game, in October. This will be an opportunity for us to gather feedback on the major changes done with this Update and learn of any critical bug that would need fixing before it goes live. Your feedback will be crucial to help us improve the game!
In order to access the PTS, you will need to own a version of The Division on PC. Starting Monday, you will find The Division PTS in your games (“My Games” on Uplay, “Library” on Steam) listed separately from The Division main game.
Since this is considered as a new game, you will need to download the client entirely (about 45Gb). Note that this will not overwrite your existing client as it will be saved under a new folder name on your machine.
Note also that the first days of testing will be focused on progression between World Tiers, and thus your characters will not be transferred from the live server to the PTS. Instead, you will be able to directly create new fresh level 30 characters. “
