This is the third film in a kinda of accidental “trilogy”. The running order is: 1st film: Alien Infinity 2nd film: Alien Continuum 3rd film: Alien Omega It’s not essential to have seen the first one. But it would help you understand what is going on in this film if you watch the second film, though. Some of the characters have hard-coded subtitles, but if you need/want subtitles for ALL the characters, then there are English-language subtitles available if you enable CC.
