Gamemode 4: Ruins is the name of a custom Minecraft world created by Sparks containing a range of Gamemode 4 modules and was released for Bedrock edition on the Minecraft Marketplace. It could be played like a normal survival world, in single or multiplayer. It was removed from the Marketplace on 25 January 2024 but in the interests of preservation, the map can be downloaded for free here.

Ruins is a world download containing a mysterious ruined city at spawn (built by DuckJr). Among the ruins of this forgotten civilization, the player discovers various special broken crafting devices along with notes left by a previous explorer on how to repair and use them. Each crafter, once repaired, offers a different range of recipes. Various Gamemode 4 modules have also been converted to Bedrock edition and enhance the gameplay of this world.

Included Modules

Below is a list of included modules and their differences to the Java version. Clicking the module name will take you to the Java version page.

Module Name Module Description Differences from Java version
Bat Grenades If a player gets too close to a bat, it will explode. The explosion is fairly small and is more frightening than dangerous. Bats require line-of-sight to explode. They drop 0-3 gunpowder upon death.
Enderman Support Class Enderman will give potion effects to nearby hostile mobs like creepers and skeletons to help them fight players Spiders and caves spiders don't get jump boost. Shulkers don't stop nearby players jumping.
Damaging Snowballs Snowballs thrown by players or snow golems will deal half a heart of damage on contact with mobs. Retired from Java some time ago. Now a Bedrock exclusive module
Ink Spitting Squid Players who's heads are underwater and come too close to a squid will be temporarily blinded by squid ink. This will eventually become a vanilla feature when update Aquatic is released. No changes
Mob Conversion Similar to curing zombie villagers, cows can be infected and turned into mooshrooms by splashing them with a poison potion and feeding them a red mushroom. Zombie Pigmen can be converted into pigs by splashing them with a speed potion and feeding them a golden carrot. Mooshrooms are made using poison instead of slowness potions. Cure items are fed to the mob instead of being thrown at their feet.
Custom Crafters See crafting and recipes section below Due to Bedrock limitations, crafters cannot be created. The player must use the existing crafters found in the ruins.
Master Crafting See crafting and recipes section below No changes
Disassemblers Allows you to convert metal and diamond tools and armour (that hasn't been damaged) back into diamonds and ingots. Placing the item into the first slot of the disassembler will break it down with a high chance of loss. See below for a detailed disassembly table. The disassembler is a hopper not a dropper. Material return chances are calculated differently.
Heart Canisters Allows you to craft an item that incrementally increases your maximum health. See below for more details. Due to Bedrock limitations the functionality of this module has been completely changed.
Speed Paths Grass paths (created by using a shovel on grass) will give players and horses who walk on them a speed effect. Horses are also given speed.

Heart Canisters

Heart Canisters are craftable items that can be eaten to permanently increase your maximum health. Crafted using the Canister Crafter, up to 10 additional hearts can be added for a total of 20 hearts of player health. If the player eats a heart canister and already has 20 hearts of health, the canister will act like an enchanted golden apple instead, giving the player temporary Absorption, Resistance, Fire Resistance and Regeneration effects.

The canister crafting recipe is expensive and requires ingredients found in the End dimension.

As an alternative to crafting, Heart Canisters have a very small chance of spawning as loot in Woodland Mansions and Stronghold chests.

Custom Crafting

There are five crafters in the ruins. One in the center and one in each corner. Each crafter is initially broken and requires a repairing recipe to make it work. Each of the five crafters has a different set of recipes that can be used inside.

NOTE: On August 1st 2018, Gamemode 4 Ruins was patched to better support touch-screen interfaces. This caused crafting recipes to change. This page shows the newest crafting recipes but you can click on the links before each recipe list for images of the old recipes if you started playing Ruins before this date.

Basic Crafter

This crafter is located at the center of the ruins and offers some simple recipes to get the player started.


Complex Crafter

Master Crafter



The disassembler, unlike the other crafters, is a hopper instead of a dropper. It takes specific items in the first hopper slot and returns some of the ingredients used to make the item to the player.

The Disassembler can return raw iron ingots, gold ingots and diamonds for the following items:

  • Iron, gold and diamond axes, pickaxes, shovels, hoes and swords
  • Iron, gold and diamond boots, leggings, chestplates and helmets
  • Shears
  • Flint and steel

Only FULLY REPAIRED items can be disassembled.

Sticks and flint are not returned by the disassembler. There is a 3/5 chance for every raw piece the item is made of to survive the disassembly. e.g a diamond chestplate will return 0-8 diamonds, while a diamond shovel will return 0-1 diamonds. In each case, there is a 3/5 chance for each diamond to be returned.

Canister Crafter

The Canister Crafter does not require a repair recipe in order to start crafting heart canisters.

Notes and Planned Additions

Due to the large differences between Bedrock and Java edition it is currently only possible to convert a few GM4 modules. The ones that have been converted are included in Ruins but more will be added to GM4 for Bedrock as updates and bug fixes happen.

Bedrock Bugs/Limitations affecting Ruins

Due to an issue with the clone command, it was not possible to change the inventory names of the custom crafters so that they are called things like "Master Crafter" instead of "Dropper".

Because Bedrock has a de-sync when containers are cloned while a player looks inside: Entering a recipe will appear to cause the crafter to empty completely. It is necessary to close and re-open a crafter in order to see the result of a recipe placed inside. Once this de-sync bug is fixed, a patch will be released to improve crafter usage (if they don't fix themselves). This does not affect automatic crafting using hoppers.
