XENOMORPH TIMELINE
Full disclaimer : I'm not affiliated at all with anything Alien/Fox related, nor the Company or Weyland Industries!
Xenomorph Timeline is just a fan site that aims to help newcomers or veteran make sense of the chronology of all the medias available for our beloved franchise <3.
The chronology is based on official informations publicly available.

Every media gets one in-universe year: the year its story takes place. When a film, book or game shows a date, that date is used. When it does not, the year comes from official guides, the publisher's own summary or the stories it connects to, and the site marks it as approximate ("around 2180").
The main sources are the works themselves, the publishers (20th Century Studios, Titan Books, Marvel, Dark Horse, Free League) and Xenopedia for cross-checking. Every entry was reviewed again in October 2026.
Each story is also sorted into Canon, Alternate or Legacy. The rules are on the canon explained page.
