Gameplay
Crackdown 3 retains the core gameplay of Crackdown and Crackdown 2, featuring a number of different organizations controlling the city of New Providence that players need to take down by killing their bosses and Kingpins, destroying their facilities, and destabilizing their infrastructures. Players can use a variety of weapons to achieve this end, from guns to grenades to rocket launchers, as well as their own physical power. Players can also drive any vehicle found in-game. The game features the "Skills for Kills" system as found in previous games, in which killing enemies with different tools and finding pickups hidden throughout the city award the player with orbs, which increase the player's core skills – agility, firearms, strength, explosives, and driving.
Crackdown 3 includes a new system known as "Gangs Bite Back", in which a boss's or a Kingpin's attention can be drawn to the player upon destroying locations and elements that they specialize in. Gang members can retaliate for these actions at any time and in any place. If enough retaliations are beaten back, the bosses and Kingpins can come for the player personally. Another new element is the inclusion of destructible environments in a competitive multiplayer mode, Wrecking Zone, in which the entire city is destructible.
Plot
Ten years after the events of Crackdown 2, a terrorist attack from an unknown source kills power around the entire world. The Agency is thrust back into action after the attack is traced to the city of New Providence, controlled by the mysterious organization Terra Nova. After the Agency's first strike against the organization fails, the player characters - super-powered Agents - are called into the field by the Agency's Voice (Michael McConnohie) and led by Commander Jaxon (Terry Crews) as a last resort to dismantle Terra Nova any way they can.
