Knights in the Nightmare hitting PSN and stores in October

Knights in the Nightmare is leaving Japan, and heading west on October 19.

To get you ready, Atlus released a trailer for it which you can find below.

Originally released for DS in 2008, the RPG-shooter mix was re-released on PSP in Japan back in April.

This version contains all-new controls, an opening anime movie and a catalog of in-game dialogue for players to browse through.

Here's the backstory:

Somewhere between heaven and the underworld -- in the center of a quiet lake -- stood an ancient castle known as Aventheim. One night, without warning, denizens of the netherworld emerged and slaughtered the kingdom; nary a soul was left alive.

Within an abandoned, long-forgotten church deep in the woods, a wisp is set free. Bereft of memory, it is drawn toward the monster-infested castle and re-awakens the souls of the vanquished knights, leading them back towards the fallen stronghold to confront the very forces of evil that took their lives.

Luckily, you have three options of getting it for yourself come October 19: Drive to the store and buy it, order it online, or download it via PSN.

Choice is a good thing.

Enjoy the video.
