After Prometheus and Alien: Covenant were met with less amazing responses from Alien fans and critics, Alien: Romulus tries to take the franchise back to its origins. Along the way, it takes a look back at essentially every other major piece of media in the Alien series, calling back iconic lines and mirroring unique scenes and images. It spends a lot of time revealing how much the original movies, Alien and Aliens, influenced it, but it’s drawing from everywhere–including Alien: Isolation, the phenomenal 2014 video game.

The references in Romulus range from overt to subtle and contain a few that even a true Alien fan might miss. Here are all the homages, callbacks, Easter eggs, and references we caught–let us know if you find anything else in the comments below.
