In the making of my current WiP 'Urban Maul', I had the idea to add these weapon tables to it. I made 3 variants, each shown in the pics.
Just take everything in the 'Weapon Table Prefab' Folder and put it in your steamapps/common/left 4 dead 2/bin/prefabs folder.
Autoshotgun, Desert Rifle, Incendiary Rounds
Hunting Rifle, Combat Shotgun, Explosive Rounds
AK-47, Pump Shotgun, First Aid Kit
There is also a Magnum spawn for all variants.
Add suggestions below for more variants, and I might just add them.
