Gaming Union writes: "In the latest issue of Famitsu, it was revealed that Sting would be releasing a PlayStation Portable port of Knights in the Nightmare, which was released in North America by Atlus last June on the Nintendo DS.
The game garnered less than impressive sales in Japan, which explains why the developer would be porting the game over to cover their losses. Sting has been known to do ports such as this in the past, most recently with Riviera: The Promised Land and Yggdra Union. But unlike those games, it is hard to see how Knights in the Nightmare can make a proper transition to the PSP."
