Skulls

Summary
Skulls are a supernatural enemy type in Leaden Sky and the second enemy type to be fought overall, they appear in Kyle's nightmare and some underground sections in the outskirts of the city.

Never attacking directly, they target the player by summoning Apparitions which cause damage upon physical contact with the player and are capable of traveling through walls, floors, ceilings, objects and other paranormal creatures. Apparitions are weak to light, dying immediately upon being hit with the beam of the player's flashlight, and are also immediately destroyed upon being shot by the player.

They are incredibly fragile to small arms fire, but in return they have the incredibly dangerous trait of exploding upon death, something they also do even if they aren't killed by merely getting within a certain distance of the player. Explosions caused by them are larger than that of the explosions caused by red barrel, but seemingly roughly as strong, making them dangerous to allow anywhere near the player.

It is currently unknown if Skulls are caused by humans being mutated supernaturally or not, however as with all paranormal phenomena it is known that they only began appearing once structures like The Tower were constructed by the Mercenaries.

Appearance
Skulls are small, floating, bleached skulls that have their mouths permanently agape as if screaming in agony and are permanently bathed in a massive flame.
