Overview
- Bethesda will release Update 66 as a free download on March 3 for PC, PS5, and Xbox Series X.
- A new ‘uninvited guest’ system can spawn extra bosses after activities, including Bigfoot as a rare four‑star encounter with a five‑minute despawn timer and an exclusive Thrillseeker mod, appearing more frequently at launch before settling to roughly once per hour.
- Roughly 50 events and activities have been adjusted with clearer icon distinctions, tighter timers, and XP that now scales with player level, with activities tuned for smaller groups and public events built for larger crowds and bigger rewards.
- Quality‑of‑life and balance updates include a faster, more responsive Pip‑Boy, a Recipe Book and Keyring to cut inventory clutter, reduced stored‑armor weight, and standardized base stats for Under Armor.
- Season 24, titled Rip Daring and the Cryptids from Beyond the Cosmos, launches with the update and is slated to run until April 7, with some low‑use activities such as Dogwood Die Off and Jailbreak being removed.
