Alien: Covenant - Prologue: She Won't Go Quietly (2017)

"She Won't Go Quietly" depicts Daniels having to combat a Xenomorph that is loose aboard the Covenant. The video is notable in that (unlike the majority of the short films created for both Prometheus and Alien: Covenant) the events it depicts are incongruous with the feature film, and thus it clearly cannot exist within the same continuity.
