Dying Light is an open-world first person survival horror video game developed by Polish video game developer Techland and published by Warner Bros. Interactive Entertainment. It was released in January 2015 for Microsoft Windows, Linux, PlayStation 4, and Xbox One. The game revolves around an undercover agent sent to infiltrate a quarantine zone in a city named Harran. It features an enemy-infested, open-world city with a dynamic day and night cycle where gameplay is focused on weapons-based combat and parkour free running.
At night the infected transform to become much more dangerous. Without daylight, the senses of the infected become more acute and accurate. They gain the ability to sprint after the player and have increased damage, as well as the ability to jump and climb buildings like the player. In order for players to avoid contact, they need to use their ‘Survivor Sense’ to locate the infected in the dark to stay out of their way. If spotted and trying to escape their pursuers, players can use distractions and traps to lower their numbers. Players can use sound to lure the zombies. The player’s main defense against the infected is ultraviolet light, which slows down the infected.
