Of all the resources available to you in AitD: Illumination, light is the most abundant and yet the most precious. The monsters that infest Lorwich are nearly invincible in the dark, but light removes their thick carapace and leaves them vulnerable to your attacks. Fortunately, there are a number of light sources available to players throughout the game.
Each player is equipped with a flashlight that when shined on monsters will momentarily stun them, make their skin crack with blue light, and most importantly, make them partially vulnerable to gunfire. When playing cooperatively, as more players shine their lights on any one monster the effect is multiplied until the monster is left defenseless. Communication is imperative to survival, and players will benefit from focusing their fire on single enemies.
Additionally, there are strong light sources scattered across the maps, including fire barrels, lamps, and overhead lights. These light sources remove 100% of nearby monsters’ defenses, and cause their skin to crack with gold light. In this state, even small arms can quickly take down an otherwise unmanageable foe. While these light sources are invaluable, they can be extinguished by monsters - and once they’re gone, they’re gone for good. The only exception is electrical light sources, which can be repaired by the Engineer. While formidable on her own, this passive skill can be her most important contribution in cooperative play.
Players will often find themselves alone and outnumbered with no strong light sources available. While the flashlight works in a pinch, you’ll expend too much ammo to make it your primary strategy for survival. Fortunately, each character has at least one special ability, which creates its own light source and always deals 100% damage. The Hunter has a flamethrower, the Priest has the Wrath of God, the Witch has Chain Lightning, and the Engineer has the Tesla Wall.
Use these skills wisely and sparingly to ensure your survival, as you make your way, Alone in the Dark.
