Gameplay
The game had a unique feature; along with the action sequences and point-and-click game elements, there was a "popularity meter" that would go up or down as Nightshade performed good deeds well or poorly. Higher popularity meant greater recognition by everyday denizens of Metro City and allowed Nightshade access to more areas. The game also included fighting segments, that required quick button responses.
Instead of a save feature or extra lives, the villain Sutekh would throw Nightshade into a deathtrap. The first four traps each had a solution and Nightshade would escape back onto the streets of Metro City (minus some popularity points). The final one does not, and the player would have to start over from the beginning of the game. Additionally the game begins with Nightshade tied to a chair, next to which Sutekh has placed a small bomb. While technically not a deathtrap (the bomb, if not escaped on time, does not do lethal damage) this introduces the trap escape, problem solving element early on.
