Backyard Monsters Walkthrough and Guide

Print page (no screenshots)   |   Print page


Inferno is a world that was added to Backyard Monsters in early 2012. You can access it as soon as you have a Level 5 Town Hall, and defeat Moloch and his army.

Once you have the Level 5 Town Hall you will be able to build the Inferno Cavern. Moloch and his army will then attack you on five different occasions. After the fifth one, you are able to enter the cavern and destroy Moloch himself. This will grant you the ability to have an Inferno Yard.

The Inferno Yard has different Monsters and Buildings, but they share similarities with the above-ground items.



Bone Cruncher:
This is the equivalent of the Twig Snapper.

Coal Extractor:
This is the equivalent of the Pebbles Shiner.

Sulfur Swirler:
This is the equivalent of the Putty Squisher.

Magma Pump:
This is the equivalent of the Goo Factory.

Resource Pod:
This is the equivalent of the Storage Silo.

Magma Tower:
This is the equivalent of the Tesla Tower.

Quake Tower:
This is unique and can be built above ground once you have unlocked it. You need Inferno resources to be able to build it either way).

This is the equivalent of the Sniper Tower.

Blast Tower:
This is the equivalent of the Cannon Tower.

Infernal Academy:
This is the equivalent of the Monster Academy - except you obviously train Inferon monsters with it.

This is the equivalent of Housing, a Monster Bunker and a Flinger all rolled into one.

This is the equialent of the Town Hall.
