He runs public scripts that were modified for epoch, same as we do on our legion server.
His Chernarus Server has a custom loot spawning script he adapted to the a3mp chernarus map, and fixed up the files to run in tangent with it. Which is just awesome, and he gets all the credit for that one. He was the first out of all us to get Chernarus up and going, but I doubt he is just going to give you his server files. Even with his mission .pbo, you'd still have to write a new script to call to from server side.
Jester, i highly doubt you even run an A3 server, so why are you going around asking for files for? you were banished off our server for glitching into bases, so if you are running on Mike's server - i hope you are practicing more restraint.
