Ahead of the Doctor Who series seven opening episode, we've been asking ourselves exactly what is The Asylum of the Daleks? Well this new 40-second trailer doesn't answer that question, but it does raise a new one - what is the Predator of the Daleks?
“The Asylum must be cleansed. The Predator of the Daleks will be deployed."
It's a Dalek voice uttering those words, before the Doctor says "I'm not a predator, I'm just a man with a plan."
There's also a blink-and-you'll-miss-it glimpse of the legendary Special Weapons Dalek, which we know could take out your average Dalek without too much effort.
All in all it makes that final question just a little bit harder to answer: "Who killed all the Daleks?"
Who do you think?
