Winter isn't the only thing coming on Season 7 of "Game of Thrones" — all-out war is here!

A new promo released on HBO Spain's Facebook page features footage from Season 7 and most of it teases a clash of the various titans: Daenerys Targaryen's invading army, Cersei Lannister and her royal soldiers, and the Northern lords commanded by Jon Snow.

Most of the footage is behind-the-scenes, showing the battles being filmed. There's a cool shot of soldiers getting torched by fire — add in a CGI dragon and it looks like Daenerys could be deploying her babies as the ultimate weapons.

There are also brief glimpses of Daenerys getting her first look at Dragonstone, a new maester character in the Citadel, Jaime riding to battle, and Brienne and Pod training with swords.

"Game of Thrones" Season 7 premieres July 16 on HBO.
