The ongoing mythology in the Assassin’s Creed video games is, to put it mildly, bonkers. Oh, it may seem like it’s a relatively straightforward story about people stabbing other people throughout history, but there’s a whole present-day angle to it that the trailers for the movie version have wisely highlighted (so as not to trick anyone into thinking this isn’t a sci-fi action thriller at heart). This latest trailer, though, takes that openness even further, name-dropping a significant object from the games’ mythology that connects the series to aliens and a pre-human civilization that used to live on the Earth. It remains to be seen just how big of a leap the movie will make into that particular rabbit hole, but it just wouldn’t be Assassin’s Creed if it weren’t throwing caution to the wind and praying that there’s a convenient pile of hay at the bottom of that fall.

Anyway, Assassin’s Creed will be in theaters on December 21.
