HBO has unveiled another glimpse into the upcoming sixth season of "Game of Thrones" with this video focusing on the prosthetics -- primarily, those for the White Walkers and wights, with some Stone Men and giants thrown in for good measure.

If you're looking for clues to the new season, you may find a few in this video: There's a shot of sizeable army of White Walkers and wights, as well as glimpses of the Night's King and some of his forces at a weirwood (presumably the current abode of Bran and the Three-Eyed Raven).

"I don't think I've ever worked on a project that has such a varied amount of prosthetics," says Barrie Gower, the drama's prosthetic designer. "You have such a variety of things to make that it's very rare that you'd be on a project that you'll be decapitating somebody the one week and then you'll be doing a full-body prosthetic the next week."

"Game of Thrones" returns Sunday, April 24, on HBO.
