During the day, players will traverse an expansive urban environment overrun by a vicious outbreak, scavenging the world for supplies and crafting weapons to defend against the growing infected population. At night, the hunter becomes the hunted, as the infected become aggressive and more dangerous. Most frightening are the predators which only appear after sundown. Players must use everything in their power to survive until the morning's first light.

Techland and Valve have teamed up for a homage to the cooperative first person-shooter, Left 4 Dead 2, by creating a 4 day crossover event within Techland’s Dying Light. 

In this 4 day event commencing October 24, 2019, Zombie slayers will experience an increased number of Virals, waves of attacking hordes, an intensifying fight for survival, along with an increased amount of guns and ammo at your disposal.  

Those who complete the challenges will be rewarded with three event exclusive Gold blueprints that will let them craft the following iconic Left 4 Dead 2 weapons (Electric Guitar, Frying Pan, and Golf Club) to use in Dying Light.

The four day event starts on October 24th, and will be available for both PC and console players. After the event concludes the standard blueprints for the Left 4 Dead 2 weapons will be available as a free DLC.
