the railway is supposed to connect to c2a4h (questionable ethics) which is a mod i have installed but it doesnt go there

Mod is dead

Apprehension before my marriage

@faringanlaster I think the author has stopped development

can you please expand the last sections of map and include the areas from Azure Sheep

@pacmanproductionsz27 Did you download the pre-disaster core?

There is small rainbow signs everywhere that say "ERROR" that have guard voice lines there is also some with scientist lines so is there any mods you need for this?

Can you make "pre disaster superbus via incintiae"
?

the elevator in the crazy huge pit section doesn't seem to work - also has a missing texture when you activate the button panel inside it after noclipping. Other than that, it was great exploring the place

Though, I suppose it's quite likely that the area was actually flooded before the disaster, since it seemed to be abandoned? (might be wrong though)

Feel like the cage room should be deflooded too, as it wasn't originally. Also the helicopter removed too.

ahaha that's a great idea

I really hope somebody when all of the pre disaster maps are done does a full pack of the pre-disaster maps where the experiment at the start goes well and Gordon goes for a walk around the Facility

hmmmmmmmmmmmmmmmmmmmmmmm

The scientists are using the area as a temporary ichy laboratory.

but the ichyosaur is in a place that is flooded so i dont think that place is supposed to be flooded

@duckrotation that's because of the xen beta. I'm not going to patch it until after the full release

"Node Graph out of date. Rebuilding..."

@Daxdub360 Keep in mind that the Ichyosaur was contained in that area pre-disaster.

I Think You Should Remove The Ichyosaur And Water Where You First See The Ichyosaur.

that look like normal

Surface tension would prob be the hardest map to make pre-disaster besides the Xen labs.

still no surface tension ;-;

I'm sure there will be a work-around. Considering the frozen room can kill you by inflicting cold damage.

Vents are required to access the final area of the map in the original game (frozen room to the section before residue processing).

also the shark cage seems to be very very old not recent or modern maybe the crossbow

Since the scientist where being conservative and using as much space as possible they used abandoned post-renovation sectors for reasearch ect.

You didn't need to use vents to access different sections of this map. The map was flooded and you traversed the waters to connect to the different sections. In the last screenshot, there is no water in the silo meaning you just walk to the other section. For example, to access the room with the shark cage where the Ichy makes an appearance, you just walk from the silo to the shark cage room. That's me presuming that is what the map creator is going for, mind you.

ON TOPIC: I wonder how this map will connect the different sections. Will it be the same to where you need vents to go through or will there be new rooms made connecting different sections.
OFF TOPIC: I realized that in the Xen trailer there are labs in Xen. I feel sorry for whoever is insane enough to try to make a pre-disaster version of that when it comes out.

T'was, yes

Makes sense, the original name for the chapter was 'Abandoned Silo' after all.

Apprehension is arguably the most confusing place in Half-Life because no one can really seem to piece together what the place actually was used for. I theorise that it was, as Elan and MacAttack pointed out, abandoned due to old age and lack of purpose and maybe Black Mesa started plans to renovate the silos for modern use. However, with the shark cage randomly sitting there and modern equipment already present in the old makeshift labs such as computers, I suspect scientists were secretly using these labs for aquatic study. The scientist remarks about the Ichthyosaur which hints maybe the Ichthyosaur you fight is the very first one captured and maybe this area was ground zero for studying the creature before they created modern labs in the Biodome Complex to properly study them in a modern environment.

@below I actually didn't know that. Thanks! The ladder catwalk still does have some issues tho. You can fall through certain solid parts of it.

also black mesa was renovating this sector as well as the whole decommisoned transport to OSHA and black mesa modern standards.

well in apprehension alot of the in-work places where flooded during the cascade

A lot of Apprehension wasn't destroyed due to the invasion, it was abandoned even for the disaster took place.

I really like the pre-disaster maps. It is great to see what the place looked like before Xen destroyed everything. I only had three problems with this map. The first was the "node graph out of date" thing that only appeared once. The second is that the shark cage should really be blocked / lowered underwater as you appear to need to noclip to escape it. The third is that the staircase guard won't talk at all (then again it might be intentional... sorry if it is). If I had a suggestion I would suggest repairing the place a bit more (removing the gas leak and fixing the first section catwalk instead of placing ladders as bandaids). This is a great map and I hope to see this be completed.
