His hitman roots give him the abilities to use a variety of guns, while his powers can be used in five main ways including summoning a black hole, and creating little creatures to take out your enemies.
Story is a strong priority with the game as one of the top writers of the comic was hired to write the entire story for the game. Starbreeze also hired a swath of voice talent including Mike Patten from Faith No More to increase the production values. Similar to The Chronicles of Riddick, Starbreeze's standout game, the story is told through a series of real-time and interactive cutscenes. At various points in the story Jack will stand alone delivering a monologue of what's happening in the story, which is actually a clever way to hide loading times.
Gameplay is split between standard first-person shooter fare and action elements with the darkness powers that gain abilities and prominence as the story goes on. As per its name, Jack must stand in the dark to gain the juice necessary to launch his dark-power attacks.
A multiplayer mode is included that leans heavily towards the shooter side of things. Jack's powers are completely stripped away, and the only "power" left is the ability to morph into a darkling, a small creature, that lets you run fast, jump far, and crawl along the walls.
