This update will make Diablo III the second game to require the Desktop App in order to play, the first being Hearthstone.
Once the Play button lights up, you can click it to enter the game and dive into the new Patch 2.0.1 content!
The Nephalem tracks Urzael down to the Tower of Korelan and defeats him in a gruesome battle. The Reapers deploy two soul crucibles into Westmarch City to claim the souls of the dead, and the Nephalem locates and destroys them, earning the ire of Urzael, Malthael's chief lieutenant, who awaits the hero in Westmarch Heights. A fifth Act is added, which follows the Nephalem's quest through the remains of Westmarch and the Pandemonium Fortress to stop Malthael and his allies.
These timed events challenge players to fight off several sequential waves of attacking monsters, and provide rewards based on the player's success. Instead of the mostly random item properties, items now found by a character would typically have properties that could be used by the character that found it.
Summary: Season 17 is rapidly approaching, and we’ve got a bundle of item changes, new Torment levels, and quality of life changes for you to check out before the Season of Nightmares casts its dark shadow.
If you are a horsepower junky and you need a fix, look no further.
I used to have it installed and working on this machine and removed my previous install using Add/Remove Programs.
