Even if you’re tired of steampunk and zombies, this new animated movie looks like it has enough weird science and creepy horror to win you over.

The Empire of Corpses is based on a series of books by Project Itoh (aka the late Satoshi Ito), and is produced by Wit Studio, who made Attack on Titan. Here’s the official synopsis, followed by the trailer:

In an alternate version of 19th century London, the world has been revolutionized by “corpse reanimation technology” creating armies of undead who serve the living as laborers across the globe.

In an attempt to revive his dearly departed friend, young medical student John Watson becomes obsessed with replicating the work of Dr. Victor Frankenstein-the legendary corpse engineer whose research produced the only re-animated corpse to possess a soul. But when his illegal experiments put him at odds with the British government, Watson is drafted into a worldwide race to find the lost research notes of Victor Frankenstein before the secrets of the human soul fall into the wrong hands.

The Empire of Corpses will have a limited theatrical run on April 19-20; check the theater locater to see if it’ll be visiting your area.
