Deception IV The Nightmare Princess makes its debut on PS4 this week and to give gamers a taste of what to expect Koei Tecmo released a Deception IV The Nightmare Princess demo on the Playstation Network which introduces the game’s story mode and the rather cool quest mode where players can assume the role of new character, Velguirie. We’ve captured the story mode antics alongside a number of predetermined tutorial scenes from the quest mode which show how you can accomplish the objectives. It has to be said, there are more ways than one to complete each task where the beauty of the game lies in figuring out the most outlandish trap combos. Deception IV The Nightmare Princess releases in Europe on July 17th.
