High Quality Content by WIKIPEDIA articles! Each level starts with The King in a "sandbox" free play mode in which the King is able to walk around and freely explore the level. It is here the player also selects the challenges- a set of specific rules for food delivery. For example, some missions may require the player to not be spotted, others may require a certain chain combo, etc. After a challenge is completed a letter score will be given. "C" is the most common award, "B" and "A" awarded for better points or faster completion times. There are four levels- Saw Mill, Cul-De-Sac, Construction Zone, and Downtown. Each features a unique map and 20 challenges apiece. The general gameplay borrows from games such as Metal Gear Solid and Manhunt. Other characters have a blue "cone of vision" in front of them, if the player walks into this cone or if a character approaches the player will be spotted.
