Template:Infobox Knights in the Nightmare is a strategy RPG from Sting Entertainment, and the fourth episode in the Dept. Heaven saga. It will be released by Atlus in North America on June 2.
Sting released a special edition version of Knights in the Nightmare, called the "Knights in the Nightmare DHE Series Special Pack", and it includes a copy of Yggdra Union: We'll Never Fight Alone for the Game Boy Advance.
Battles take place in real time on an isometric grid. The wisp, controlled via the touchscreen, moves around and is how the player gives orders to allied units. When the wisp comes into contact with a unit that can act, an item can be selected, and the attack must be aimed by moving around the wisp. However, the wisp will be under constant enemy fire. The player must guide the wisp to dodge the shots as well as order the allied units to attack.
However, despite having a timer, time is only deducted for charging attacks and when the player's wisp takes damage. Thus the player has "unlimited" time to plan strategies and in this manner resembles other strategy role-playing games.
Permadeath exists as characters have a vitality stat which decreases when they use skills and other special circumstances. Vitality is replenished through leveling up, Transoul System, and other special circumstances.
