Going Nowhere Studios has debuted a pretty impressive trailer for Deathstroke: Arkham Assassin, a fan-film prequel to the Warner Bros. video game Batman: Arkham Origins.

In the game, a bounty is placed on the Dark Knight by the Black Mask, bringing eight of the world's greatest assassins to Gotham City on Christmas Eve -- including the formidable Deathstroke. But as the trailer teases, the crime lord requires a demonstration of his skills.

The short film is set to premiere Monday online.
