There are two different types of Map in Zombie Master. Fun maps and Serious maps.
Serious maps are mostly objective based and can take a long time to complete. These maps rely on the strategy aspect of Zombie Master.
Fun maps are for casual rotinajs looking for an instant of fun. These maps are not as lengthy as serious maps and occasionally do not have zombies thus creating a great debate that these should be made for Gmod and not ZM, eventually the 'fun' maps overcome the good ones making the developers dissapointed and killing ZM in the end for good.
