These descriptions are dated. Our source's newest post is August 2025. Event shape is stable — a bi-weekly event stays bi-weekly — but rewards, scoring and exact timings change. Treat the shape as reliable and the specifics as needing a second look.

Three events are missing. Dead Rising and Wasteland King — their pages are long walkthroughs with no sentence that says what the event is, and we would rather leave a gap than write a definition ourselves. Lairathon — our source describes it as one alliance's own activity, not a game event.
