Events are shared quests that spawn around the world and are only available to be completed for a limited amount of time before they despawn and go back on cooldown. Any player character can participate in these event quests, regardless of level, and some event quests encourage player characters to team up to complete the objective. These quests are displayed under the section "EVENT" of the Pip-Boy.
Some events are triggered by any player character approaching an event's location. Each event has a time limit to complete. Any player characters can participate by traveling to the location or refuse to by avoiding or leaving the area. These quests can be repeated every 1 hour and 12 minutes.
Public challenges are a new form of public events that will be introduced in Tales From the Stars. While similar to seasonal events, public challenges will be of a global range to the World, encouraging players to rely on each other to succeed.
↑2021 Bethesda AMAMark Tucker: "We’ve been talking (internally) about doing something fun with the Zetans since before we launched the game, so we are excited to finally have the chance to do something with them. We are working on a new feature we call Public Challenges that will be similar to Seasonal Events, but will be global to the World and encourage players to work together to succeed. We will showcase the Zetans in our first one and plan to add more in the future."
