I made a weapon based on Noriaki Kakyoin' Stand, Hierophant Green, from the manga/anime: Jojo's Bizarre Adventure: Stardust Crusaders.
In fact I made it 2 years ago, was saving it as an easter egg for a map I never finish, so... Yeah.

The Weapon:
weapon_standhgreen / Hierophant Green


Installation

Extract the .rar content inside Steam\steamapps\common\Sven Co-op\svencoop_addon\ and edit the "default_plugins.txt" file located in Steam\steamapps\common\Sven Co-op\svencoop\ adding these lines:

Code:
"plugin"
    {
        "name" "Stands"
    "script" "../maps/stands/stands_register"
    }
As map_script:
Extract the .rar content inside Steam\steamapps\common\Sven Co-op\svencoop_addon\and edit any ".cfg" file on the maps folder, adding these lines:

You can add the weapon too, so everyone can start with them.
Code:
