The game involves a series of puzzles where the player is to avoid the infected blade in-order to hit the "P2" panic button hidden under these blades. And in-case the player touches a sharp edge, a jarring splatter of blood splashes the screen and the puzzle will reset. Between each level of the game, a screenshot or a concept art related to the upcoming game Prototype 2 is displayed. This application can be downloaded on iTunes. * Slice HD. * Slice SD.
