Major additions
The September 2 version 1.0 release completes the story and adds Infinite Endless Vault, four weapon aspects associated with Endless play, Shop Level 5, the Bomb Path, and Hardcore. The announcement also names new vendors, codex content, cosmetics, and quests.
Reading older guides
An Early Access guide may still explain the core dungeon-shop loop, but it cannot cover the finished story or all launch systems. Check its publication date and applicable version. When an item, perk, vendor, or route disagrees with the current client, prefer the 1.0 announcement and live interface over the older instruction.
