Pearce sliding over a car, demonstrating freerunning.
Freerunning is a form of parkour acrobatics, in which participants navigate through a landscape by performing fluid movements over and across urban or natural structures. Aiden Pearce is able to freerun in Watch Dogs by jumping, evading, and dodging obstacles and leaping over objects such as cars and benches. Criminals are also seen to be capable of freerunning when running away from Pearce. Raymond "T-Bone" Kenney can also freerun as seen in the Watch Dogs: Bad Blood DLC.
As of Watch Dogs 2, freerunning has been improved, allowing for more acrobatics to traverse the environment, and can be used to start "combos" for attacking enemies.
