Bad Blood is a Player versus Player (PvP) expansion for Dying Light. Your aim is to evacuate before nightfall, scavenging weapons and attempting to harvest enough blood samples from the infected to get a set on the extraction chopper. Players can team up to take down bosses and split the goods, or turn on one another and ransack their blood samples. “Make sure you have enough evacuation points once the chopper arrives, and don’t get killed as you race to the extraction zone.
