To give players something to do when they are trying to fill the server I am thinking of having bots for them to play against when the player count is low.
Basically until there is at least 10 humans there would always be at most 5 bots which would all become zombies each round. I am going to try to see if I can intercept the first zombie if it is a human so that no humans will be made a zombie in these cases at the start. When there is 6 humans there would only be 4 bots 7 3bots so that when there is 10 humans there is no bots. Note that at 6 humans a human can be a zombie in addition to all the bots becoming zombies.
I think this can be a way to help seed the server. What do you all think?
