For some reason, it conflicts with star wars lasers or any other mods but it works perfectly fine without any problems or crashes. I'm not the original author so I can't fix any other issues. 

What's edited/removed:
Custom weapon models and sounds - Removed so u can use your own without crashes. 
sound.cache file (aka custom music) - Removed it to prevent the finale to crash. 


What needs to be disabled to prevent crash:
Disable any custom particle or vision correction mods. (The Following Mods are Thirdstrike saturation boost by мяFunreal, Boomer Glasses, Enhanced Mud/Gas Droplet Overlay and any other mod that changes/replaces your vision when get attacked by certain special infected, uncommon infected or replaces your vision once you're black and white.)
Disable all mods that change common infected because this map contains a lot of uncommon infected. 


Required item for this map to display textures:
Symbyosystexturesfull - Required for this to work


About playing multiplayer in this map:
I'm not sure if it works in multiplayer. I will test it someday. You can test it to see if it works.


Message to Emilio3:
If you see this map, don't get mad at me. I only removed sound.cache file so the finale won't crash, custom weapon models and sounds are removed so u can use your own.
