FUMBLING IN THE DARK
Turn on the generator using no more than 10 chemical lights. (Ch. 3)
The Evil Within The Consequence FUMBLING IN THE DARK Achievement / Trophy Guide
Early in Chapter 3 of The Consequence DLC you will lose your flash light. The Rooms are pretty much completely dark and you can only use chemical lights.
They don’t do much while you hold them and only generate light when you throw them. Luckily the way to the power generator is a very short one and you can use 10 chemical lights on the way. Once you turn the power back on the achievement / trophy will pop.
