no, its not random. When you first join single player the first round of any map will have a significant increase of zombie spawn rate and max zombies allowed. But when you die for the first time on that map the max zombies allowed goes back to 24. and if you want the same amount of zombies as last time then you will have to leave the game and join multiplayer again.
