Crackdown 2 is modeled similarly to its predecessor Crackdown, a third-person shooter in open worldgame play. The player character is an advanced super-powered officer for the city-funded “Agency”, known simply as the “Agent”. This time around, players choose one of four faces and armor colours (eight colours if they pre-ordered it), instead of just the preset heads offered before. Along with that, the orbs have been carried on from the first game, and the Agent’s powers are expanded and enhanced such as the Agility Skill which now allows the Agent to jump higher than in Crackdown, glide, and gain access to the helicopter landing pad at the Agency Tower. The player is able to commandeer any number of vehicles in the game, including Agency vehicles, Peacekeeper Cruisers and a large number of civilian vehicles that the Cell have armor plated. Checkpoint races are back, both Road and Rooftop versions. Like Crackdown, the game allows for on-line co-operative play in the main game, but now supports up to four players. The game also features competitive multiplayer modes for up to sixteen players. While the Crackdown supported System Link playing for co-op, Crackdown 2 does not feature the same option. Microsoft Producer Peter Connelly stated: “It would’ve taken a half-day of work, for something that only a tiny percentage of gamers will ever use.”In Crackdown 2, the player fights both the Cell, a terrorist organization, and “Freaks,” strange infected mutants. Both organizations’ members can be killed with melee attacks, explosions, and bullets but there are special UV weapons made for the Freaks, who cannot survive in sunlight. There are five skills to be leveled up: Agility, which the player increases by collecting Agility Orbs and Renegade Agility Orbs, by doing Rooftop Races, or by killing enemies from a highly elevated location; Firearms, which is increased by shooting both handheld and mounted guns; Driving, which is increased by running enemies over, power slides, handbrake turns, completing Road Races, jumping through Stunt Rings and collecting Renegade Driving Orbs; Explosives, which is increased by using explosives, both Launchers and thrown Grenades; and Strength, which is increased by using hand-to-hand attacks, throwing objects, beating people with those objects, or using the moves you unlock as your Strength increases, such as the Charge or Ground Slam.
