guys i need a solution when i open the game there is no server in zombie mod and also in multiplayer

SpazmicParadox there are no ai bots in zombie mode. The game never had that and it would be alot of work to write an ai bot script since the bots couldn't just stand around and do nothing, they would actually have to interact with the map and avoid being killed by zombies.
