'Westworld' is coming back for a second series next year, but already here's the first trailer to whet your appetite.
As you can see, things have gone from bad to worse. And blood-stained music sheets are just the start of it.
The wild west-styled theme park is littered with corpses, as the robots continue to get back at their human creators. Ed Harris and Thandi Newton return for series two, as do Evan Rachel Wood, James Marsden and Jeffrey Wright.
Based on the 1973 film of the same name, 'Westworld' is set in a fictional theme park that lets stressed business people from the city live out their fantasies in a make believe wild west setting.
However, when the robots start to disobey their programming, they rebel, and fight back against their human creators who have treated them so harshly.
It's a joint production between HBO and Sky. In the UK, it airs on Sky Atlantic.
The series is executive produced by Jonathan Nolan ('The Dark Knight'), JJ Abrams ('Star Wars: The Force Awakens') and Lisa Joy ('Burn Notice').
The new trailer aired at Comic-Con last week. But it wasn't the only new trailer to debut. Netflix revealed the new spot for 'Stranger Things' series two, and it's full of 80s nostalgia including Michael Jackson's 'Thriller'. Take a look.
The new 'Game of Thrones' trailer sets the scene for the remaining five episodes of the penultimate series. In it, we hear Petyr Baelish tell Sansa Stark: "Every possible series of events is happening all at once."
It also shows lots of different armies across the Seven Kingdoms gearing up for war.
Finally, AMC revealed the trailer for series eight of 'The Walking Dead', and it features zombies aplenty.
