I made a local cope of this mod to see what's in it, and here are the highlights.

In the "gfx" folder I found a low quality image called "spalling".
I believe it to be something anime related.

In the files of the "HealthSystem UI" folder I found an image titled "R".
It's Walter White. (Transparent PNG)

In the "icon" folder
I found several gun attachments of the devs of Mors Longa
You can find two of these attachments using the "loot" panel in the debug menu.
Although I can't find the rest of them.

Also in the "icon" folder is many unused items.
These include, cigs,"container, gasen, vodka, and many more.

In the "images" folder
I found "ainsley".
"AYO UR NOT SUPPOSED TO SEE THIS
oNLY YOU CAN see this text because you opened it with ms paint or something.
PLS STOP LOOKING AT ANSLEY" -"ansley" image 2022
You can open pictures without using ms paint, Devs.
Apologize right now for this horrible mistake.

I also found a Phantom Forces reference.

In the "main" folder
I found "UntilDawn" which appears to be a menu concept for a mod.
The menu has a purple outline and purple text.

In the "Melee Weapons" folder
I found a scythe that looks pretty cool.

In the "prefabs" folder
I found a naming scheme.

Originally posted by Naming Scheme:

prefabs = {
enemies = {

mil = {
infantry = {
ranged = {
soldier1,
soldier2,
soldier3,
soldier4,
officer1,
officer2,
sniper1,
sniper2,
},
},
vehicles = {},
},

insurgent = {
infantry = {
ranged = {
aggressor1,
aggressor2,
aggressor3,
elite1,
elite2,
elite3,
elite4,
},
},
vehicles = {},
},

}

In the "vox" folder
I found "Empty" which contained a single grey voxel.

That's everything I could find.
I hope you found this interesting.
