This is a DLC and needs Base Game Dying Light.
Dying Light: Bad Blood is a multiplayer battle royal game developed by Techland. You are one of the 12 players released onto the map, with a single task in mind — survive! No zombie and certainly no human will stop you, as there are no other options but to be the last one standing at the end of this massacre.
Use your wits, your skills, and your game knowledge to strive in the environment specifically designed to end you. Parkour your way out of danger, and when there’s no other choice, fight in a melee combat with all your might, it’s either you or them. Twelve comes in, one goes out.
