HBO released a new trailer for “Game of Thrones’” sixth season and it hinted more deaths are coming this season.

The 30-second footage highlighted deeply frightening messages, Los Angeles Times noted.

The trailer opened by Tyrion Lannister, played by Peter Dinklage. Tyrion is speaking of taking part in a great game. “Are you afraid? You should be. You’re in the great game now. And the great game’s terrifying,” Tyrion said to Daenerys Targaryen (Emila Clarke).

Then The High Sparrow, played by Julian Glover, chanting how all deserve death, and finally hearing Jaqen H’ghar, played by Tom Wlaschiha, making assurance that “a face will be added to the hall,” referring to the Hall of Faces in which  Arya Stark (Maisie Williams) lost her sight at the conclusion of season five.

The new trailer also offered a glimpse of the “biggest” battle scene yet that writer-producer Bryan Cogman earlier revealed, The Telegraph reported.

Meanwhile, Kit Harington opened up about how sad he is to be “done” with “Game of Thrones” and how he is going to miss the hit show.

In an interview with The Guardian, Harington said: “Thrones is an amazing thing, and is going to continue to be incredible – so it is a loss not being there, in the circus. It has had an amazing impact on my life. I wouldn’t be in this, or getting a lot of the offers I have, were it not for Thrones.”

When Harington was asked if Jon Snow is really dead, the actor replied: “He’s featured on the posters of season six… I’m really dead. I’m not coming back. I’ve got a film lined up straight after this [Faustus] with Xavier Dolan, The Death and Life of John F Donovan. I’m playing a young TV star about to break into movies, who is very troubled and finds himself wrapped up in scandal, and is unfairly set upon. It’s about his descent.”

Harington portrayed Jon Snow from season one to five. He will be coming back in the upcoming season but only in the capacity of his character’s corpse. “I filmed some scenes of me being dead – it’s some of my best work,” the actor said in an interview with  Time Out recently.

The much-awaited “Game of Thrones” season six will premiere on April 24 at 9pm on HBO in the US and will be simulcast on Sky Atlantic.
