I created Duriel's More Zombies and Larger Random Hordes (DMLRH) to provide a solution to the problem of not enough zombie spawns for a solo player.

When playing alone, it's not fun to just stand in the middle of the town and wait for the zombies to come to you. It's even less fun if they're deadly zombies or if you have to fight them.

There are many different solutions to this problem. Some players prefer to wait for a random horde to come to them, while others prefer to prepare for a specific attack, like a zombie raid.

But for me, the solution is to provide a way for players to customize their worlds by providing hordes of zombies and zombie dogs.

You can specify the level, the type of entity, the difficulty, and the other settings, to create a unique world for yourself.
