Play the role of protector, switching back and forth between Balian (Orlando Bloom) and Sybilla (Eva Green). Your mission, spelled out at the onset of each level (there are ten), is to rescue the trapped and helpless citizens of Jerusalem. You are given a requisite number of innocents to save, but there are always more peasants cowering in fear than required to finish a level. In order to rescue the extra innocents, you must explore the city blocks in greater detail, seeking out alternate routes and secret passages. What was once a quick three-minute level perfect for jamming between classes can evolve into a ten-minute challenge over lunch.
