The game is played in a first person perspective and it involves ranged weaponry such as guns, cannons and launchers. The weapon is visible on the screen, allowing the player the ability to aim it at a target. The player is unable to see what is behind or to the sides of their character unless they turn in that direction. FPS is a common choice in fast action games.
