A friend of mine is interested in modding the server software, but can't be bothered making an account for a single topic. He noticed that the only modding was replacing resource files and can't find any server documentation on modding.
Long story short, he wants to know if you can put in a damage immunity timer at the beginning of each round(think no-rush options on RTS games... but with damage and not build restrictions).
EDIT: Figured I'd throw in he's been programming for years(Mostly in C#) He says he'd also appreciate any source code for the vanilla server software if it exists.
