Thanks

i saved a few different copies of that "storm mode" you requested
depending on what fits your needs... script version or mutation version
however, my own copy merges both together, so I don't know if that's a problem
another user did reupload the original separated versions
there is also a custom version I made with "united we stand"
so, you can also enjoy the storm with all 8 survivors on any map
