Dying Light is a 2015 survival horror video game developed by Techland and published by Warner Bros. Interactive Entertainment. The game's story follows an undercover agent named Kyle Crane who is sent to infiltrate a quarantine zone in a fictional Middle Eastern city called Harran. It features an enemy-infested, open-world city with a dynamic day–night cycle, in which zombies are slow and clumsy during daytime but become extremely aggressive at night. The gameplay is focused on weapons-based combat and parkour, allowing players to choose fight or flight when presented with dangers. The game also features an asymmetrical multiplayer mode, and a four-player co-operative multiplayer mode.

Parkour is an athletic training discipline or sport in which practitioners attempt to get from one point to another in the fastest and most efficient way possible, without assisting equipment and often while performing feats of acrobatics. With roots in military obstacle course training and martial arts, parkour includes flipping, running, climbing, swinging, vaulting, jumping, plyometrics, rolling, and quadrupedal movement—whatever is suitable for a given situation. Parkour is an activity that can be practiced alone or with others, and is usually carried out in urban spaces, though it can be done anywhere. It involves seeing one's environment in a new way, and envisioning the potential for navigating it by movement around, across, through, over and under its features.
