Dying Light is an open world, action horror game. It takes place in a zombie apocalypse environment, similar to the Dead Island games by the same developer. The game is set in the large city of Harran, with influences of ancient Turkey, overrun by a mysterious epidemic. The protagonist is Kyle Crane, an undercover GRE operative sent inside a quarantine zone. His initial mission is to neutralize the rogue GRE operative Kadir Sulaiman, but he can also choose to focus on helping the survivors instead. He can freely explore the city using parkour and freerun mechanics. The game has a dynamic day and night system – during the day zombies are less aggressive, so players can gather supplies, weapons, craft items etc. and prepare for the night, when infested are stronger and more dangerous.
