Find answers about Flat Survival Expanded

Flat Survival Expanded keeps the Flat World experience but adds ways to obtain resources and access progression that would normally be limited or unavailable.

The goal is not to turn Flat Survival into an extreme challenge. Instead, the add-on expands what you can accomplish while preserving the distinctive experience of building and progressing in a Flat World.

Establish your base using oak trees, bamboo and the water, pumpkin, lava and dripstone areas. Fuel the Cobblestone Generator and Iron Extractor, then use the Gravel Crusher to turn gravel into sand.

Develop villagers and renewable resources using normal Minecraft mechanics. Obsidian from the Generator helps you reach the Nether; gather Eyes of Ender to finish activating the installed End Portal. The complete journey through the End has been validated. The machines supply essential materials at a balanced pace rather than handing out excessive resources.

Add supported fuel to the fuel chest and collect cobblestone from the output chest. Each cycle produces one cobblestone in 100 active ticks (about 5 seconds at 20 TPS) and uses 4 energy.

A lava bucket provides 400 energy and returns an empty bucket immediately when consumed. Once its entire energy contribution is spent, the Generator also yields one obsidian—normally after 100 cobblestone cycles, or 8 minutes 20 seconds of uninterrupted operation. Obsidian comes from this Generator; there is no separate Obsidian Converter.

The Generator pauses when its output is full and preserves remaining energy. Its chunk must be loaded and ticking.

The Iron Extractor uses supported fuel to produce one iron ingot every 2400 active ticks (about 2 minutes at 20 TPS), consuming 16 energy per ingot. It does not need iron ore as input.

Collect ingots from its output chest. Production pauses when the output is full, preserving remaining energy. Like the other machines, it only advances while its chunk is loaded and ticking. Its slower output provides essential iron without overwhelming Survival progression.

Yes. The complete Survival progression, including the Nether and the End, has been validated in gameplay, including earlier builds.

Use the Cobblestone Generator’s lava-fuel obsidian to build a Nether portal and continue through normal Minecraft progression. The installed End Portal starts inactive, so you still need to obtain the missing Eyes of Ender and activate it. Each frame has a 10% chance of starting with an Eye, but installation always leaves the portal inactive.

No.

Flat Survival Expanded is intended to complement normal Minecraft Survival mechanics rather than replace them.

The add-on focuses on filling progression gaps created by the limited resources of a Flat World while allowing standard Minecraft systems to remain an important part of the experience.

Place gravel in the material chest and supported fuel in the separate fuel chest. Each cycle consumes one gravel and 4 energy to produce one sand in 100 active ticks (about 5 seconds at 20 TPS). Collect sand from the output chest. The machine consumes gravel; it does not generate it.

Gravel is reserved when processing starts. The reserved material and progress survive reloads, exhausted fuel and blocked output. Already ignited fuel keeps burning during stalls, so keep materials supplied and output space available. Its pistons are decorative and it has no furnace.

A new installation adds whole oak trees, bamboo shoots, grass and flowers; water and pumpkin ponds; lava and dripstone; the Cobblestone Generator, Iron Extractor and Gravel Crusher; a villager house; an enclosed zombie villager cell; and an End Portal complex. There is no separate Obsidian Converter or acacia house.

Leo and Sam spawn once after construction, with professions handled by vanilla Minecraft. Reopening the world does not respawn or reposition them. The End Portal template has no silverfish spawner or active infested blocks. Natural features vary using an add-on seed saved for each world.

All three machines share these fuel values: bamboo: 1 energy; stick: 2; oak planks or oak log: 4; coal or charcoal: 32; coal block: 320; lava bucket: 400. Consuming a lava bucket returns the empty bucket immediately.

Only the Cobblestone Generator awards obsidian after a lava bucket’s full energy contribution is spent. The Iron Extractor and Gravel Crusher do not produce obsidian.

Machines advance only while their chunks are loaded and ticking. There is no offline production or automatic chunk loader. Saved machine state is retained when the world is reopened, but time spent away is not converted into extra output. The listed production times assume 20 ticks per second.

The original machine blocks and chests are protected against mining and explosions. Blocks you add outside the protected structure can be removed normally. Item frames are protected, but their displayed items can be removed or replaced.

Use the designated chests to operate the machines. The Generator and Extractor furnace interfaces are blocked; the Crusher has no furnace. Installed structures are not automatically rebuilt or repaired when you rejoin.

Open Beta is the stage where Flat Survival Expanded becomes available for broader player testing before version 1.0.

During this period, progression, balance and functionality may continue to improve based on testing and player feedback.

Beta releases may also contain issues that are corrected in later updates, so keeping backups of important worlds is recommended.

Every public update is documented on the Changelog page.

There you can review additions, improvements, changes, fixes and known issues for each release.

Yes, keeping a backup of an important world is recommended before installing a new beta version.

Flat Survival Expanded is designed with world continuity in mind, but beta releases are still part of an active testing and development process.

No. Installed worlds retain their saved structures, inventories and machine progress. Rejoining does not rebuild structures, repair them or respawn residents.

Older experimental layouts are not automatically upgraded to the current layout. Back up your world and check the notes for the build you intend to install before updating.
