Level 3
"Electrical Station"
Level 3 consists of a mix between Level 2 and Level 1. There are remains of pipes and building equipment from previous levels, apparently this level was supposed to be expanded. It's an Electrical Station, having a faulty power box that requires a restart upon entering. There are three main walkways to go down, two of which being useless. One of the "useless" walkways contains the faulty power box, even if it isnt required. However unless you have played through it before its smart to just turn it on.
Origin
"Electrical station" is one of few levels in the game that stays true to most fandoms naming, Due to the constant electrics running its said to be uncomfortably hot and humid, its decrepit and forgotten, hence its reasoning for having pathways that arent used, because theyre unkempt and ruined by time.
Exiting requires that you get past the smilers, the power box is optional to restart unless you know the level's layout by hand. At the exit hallway, you can either choose to proceed to Level 1 Annex 2 (to be added) or risk yourself to The Fog.
