Just figured I'd post some links to where you can find blueprints of many of the maps in flee the facility. Feel free to use these to help memorize any maps you haven't fully memorized yet.

Prison, Airport, Facility_0, Forgotten, Homestead, & Library (Maps by u/UnderstandingStill93 on Reddit) Flee The Facility Map Blueprints (Updated) : fleethefacility (reddit.com)

School (Map by u/croco_chomp on Reddit) i made a map for the school with my own labels. feel free to use it to memorize! : fleethefacility (reddit.com)

Sewer, Lab, & Optimus (Maps by u/DatIronGolem21 on Reddit) Official Map Layouts of the New Maps : fleethefacility (reddit.com)

I wasn't able to find any maps for Mansion or Nuclear so if you've made a map for either of those please don't hesitate to message me.
