Nocturnal

Together with his partner Stiletto, a former supervillain converted to the side of the good guys, he is the sworn protector of Noctropolis, a city where it's always night time because of a permanent ash cloud that hangs over it, the result of a volcanic environmental catastrophe which occurred decades before.

One night, as Peter is leafing through the newest issue of "Darksheer" to hit the stands, a courier brings him a package which eventually transports him into the city of Noctropolis, where he has to take the role of Darksheer himself.

Coincidentally enough, his arrival as Darksheer occurs at the same time as five of the superhero's deadliest arch-villains decide to gang up on him after they are mysteriously released from incarceration.

It turns out that the real Darksheer had disappeared several weeks prior to Peter's arrival.

It's up to the unlikely hero to find out who released the criminals, while simultaneously trying to keep them from wreaking havoc across the city of Noctropolis - and maybe, in the process, find a way back to the real world.

Noctropolis is a puzzle-solving adventure game, with game mechanics similar to Sierra and LucasArts titles belonging to the same genre.

Controlling Peter, the player has to interact with characters and objects, manipulate inventory items, solve puzzles and overcome the obstacles the main character will have to face to advance the story.

The game has a verb-based menu interface that appears if the player right-clicks on the screen.

It features live actors filmed over digitized graphics; many conversations and cutscenes are displayed as short movies shown inside a smaller screen.

Nocturnal for Xbox One is currently worth €63.92 loose. Prices are based on real sales and update regularly on Gamevaro.

Nocturnal has only a handful of tracked market sales, suggesting relative scarcity compared to more common Xbox One titles.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. These are tracked as separate market values because the price gap between them can be significant, especially for older releases.

The PAL version of Nocturnal is currently worth €63.92 loose, versus €57.32 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
