Dying Light: The Beast Update Introduces Nightmare Experience

"To turn up the heat on players, human and infected enemies are now smarter, more aggressive, significantly stronger, and more reactive to the players' actions. Volatiles may now even appear during the day in some of the Dark Zones, and players have far fewer resources to deal with them all. If that wasn't enough, there's a new super enemy, the Alpha Volatile. Techland calls it "the most intelligent Volatile in the history of Dying Light." It's even smarter than the traditional Volatiles and its heightened senses can track the player across the entire map unless they reach a safe zone. The Alpha Volatiles can be killed, but good luck trying to pull that off. At night, the player is the prey for this creature."

"The dev team must not have thought the new Volatiles were enough to make Nightmare Experience a true challenge. Now players have to deal with hunger, which is tracked through The Hunger System. If players don't keep their character fed, they will succumb to debilitating effects that will weaken their stamina, health regeneration, and combat efficiency. The developers even added more challenge to the game by using the flashlight--its battery can become too low to use if players don't periodically recharge or replace it."

Update 1.5 introduces the Nightmare Experience that increases enemy intelligence, aggression, strength, and reactivity. Volatiles can appear during daytime in Dark Zones and resources are scarcer. A new Alpha Volatile features heightened senses, map-wide tracking outside safe zones, and extreme lethality at night. The Hunger System requires feeding to avoid reduced stamina, health regeneration, and combat performance. Flashlight batteries now deplete and must be recharged or replaced. New finishing maneuvers for one-handed blunt and slashing weapons are added. NewGame+ and Legendary Level progression curves were adjusted to reduce farming exploits and balance difficulty.
