When you play the "Game of Thrones," you win or you die — and in the final season of the fantasy epic drama, death is coming for them all.

HBO released the first full-length trailer for the highly-anticipated Season 8. It showcases all of the major players, including Daenerys Targaryen (Emilia Clarke) and Jon Snow (Kit Harington). The latter warns that the Night King and his army of White Walkers are coming. "Our enemy doesn't tire. Doesn't stop. Doesn't feel," he says.

The trailer begins ominously, with a panicked Arya Stark (Maisie Williams) running through Winterfell and continues with a shot of an awed Sansa (Sophie Turner) watching the dragons fly over her home.

Then, there's Cersei Lannister (Lena Headey) looking smug and drinking wine (of course!), Jaime (Nikolaj Coster-Waldau) promising to fight for the living, and Tyrion (Peter Dinklage) gazing upward pensively.

Seriously, everybody gets a moment, including the recovered Jorah, Missandei and Grey Worm passionately kissing, a still-alive Tormund patrolling with an also still-alive Beric Donddarion, and even Gendry overseeing a forge.

And we see glimpses of the humongous battle that may be the longest one ever filmed.

"Game of Thrones" premieres April 14.
