The map is creative and at some points jaw-dropping (Turbine room, Vent jumpscare)

For the First few days, I've been at the area near the fake village because of how hard it is to navigate the hallways, everythings the same, and it gets easier once you get a GPS (not map cuase its just a hint to the escape).

but while the map helps to locate where you are, just how hard to know how to get to point A to Point B, you have to wander Alot of times to find new locations, with the map (GPS) only outlining A few routes.

Difficulty depends on which area you are in, I've had only 1 death so far due to tripping into a hole in the catwalk in the factory area, which I like how difficult it is with limited visibility there is with the map.

Now a few advantages and disadvantages i've found with the map...

1) is the common Problem with using 3rd person in vents or other routes to cheat other areas on the map.

2) most of the drops and ledges in the maps are a pain, most of my bones in my legs have been crumbled to dust by now from trying to fall onto the small ledge which lets you into the vent system from ladders and what not, its a little challenging but its not a big deal, most deals are the fall from ceiling vents which crushes your legs on fall.

3) Zombies are pretty easy with enough ammo or weapons to deal with, throughout my play through i haven't encountered any mega zombs or any boss like entities. (but those burners, god the burners).

4) I don't know if this was intentional or not but most crafting supplies and objects are 'Barricade' objects, and you can place them anywhere, which is helpful for most vents because you cant crouch jump in this game. but the plates have been helpful to crawl into the vents.

while most of these advantages and disadvantages are jumbled together, most issues from these haven't been a problem.

as act 4 is planned acorrding to the description of the map. the map is fun, probably more fun with a freind or team. I could see Most locations could be villages populated with other players if teamwork & trading I could see being possible.

Trams are a nice addition, but if you use them to one location and go back to another previous location, you'll have to go back to the last place you left the tram.
The NPCs, which at this time have no interaction, have no Reason to what they're doing here. I'm not saying remove them, i'm saying why is there a team of "militia" or I'm guessing they're militia, is under the first tram station.

and I've had a similiar problem in elver where I found this Female NPC during the last mission with the Elver "Storyline", Which She was only there to say "I'm so Cold", and not do anything to help her, and trying to put a campfire near wont help because of the area protection.
A similiar problem with the Scientist, the Last REMAINING and LIVING Scientist Calling for help, to which instead of helping him you just ignore him for literral Ingame MONTHS and still helplessly holding oin for dear life to escape his turbine death.

Map is fun, but I hope Act 4 will expand this, helping scientists to safety and a better GPS layout would help, It's a great map and I hope the story will explain more unlike Elver.

My rating would be a 4.5/5, But I just wanted to give my thoughts to the map creator how I liked it, and it was great entirely :D
