 The game has a brightly colored, minimalist style and differs from most previous first-person perspective video games in allowing for a greater freedom of movement with regard to its 3D environment.This allows for a wider range of actions—such as sliding under barriers, tumbling, wall-running, and shimmying across ledges; in having no heads-up display; and in allowing a range of vision which incorporated the legs, arms, and torso of the character as frequently visible elements on-screen.
