LostCities-TFC

Imagine stepping through a portal into a world where nature has reclaimed a once-great civilization, but the stones, trees, and even the flowing rivers obey the harsh rules of TerraFirmaCraft. That is exactly what LostCities-TFC delivers — a specialized fork of the popular Lost Cities mod, rebuilt from the ground up to integrate seamlessly with TFC’s unique world generation, blocks, and items. Instead of vanilla cobblestone and oak planks, the crumbling highways, bridges, and subway tunnels are constructed from TFC-specific materials, making every ruin feel authentically ancient and unforgiving.

What Makes LostCities-TFC Different?

This is not a simple resource pack swap. The mod’s creator, with permission from the original Lost Cities author McJty, has rewritten the block palettes, fluid systems, and tree generation to use TerraFirmaCraft assets. That means you will find TFC stone types forming the towering skyscrapers, TFC wood varieties lining the abandoned halls, and TFC fluids like salt water or freshwater filling the canals. Even the loot and spawners are tuned to match a TFC survival experience, offering rewards that feel earned rather than overpowered.

Because the overworld in TerraFirmaCraft is already a complex, handcrafted geological simulation, LostCities-TFC currently restricts city generation to a dedicated dimension (default ID 111). This keeps your TFC overworld pristine while letting you explore endless urban decay through a portal. The mod is still in alpha, so expect occasional quirks — but for players who love the gritty realism of TFC and the thrill of dungeon delving, it is a match made in modding heaven.

Key Features of the TFC City Dimension

• Full TFC Block Palette: Buildings, roads, and tunnels use TerraFirmaCraft stone, wood, and decorative blocks, blending perfectly with the modpack’s aesthetic.
• Highways and Infrastructure: Massive elevated highways, intricate bridge networks, and a sprawling subway system connect the ruins, offering both travel routes and dangerous encounters.
• Dungeons and Spawners: Hundreds of dungeons hide beneath the streets, filled with TFC-appropriate mobs and loot that respects the modpack’s progression.
• Customizable Profiles: Just like the original Lost Cities, you can tweak city density, building height, and ruin decay through configuration presets, tailoring the dimension to your preference.
• Fluid and Tree Replacement: Rivers, lakes, and even decorative water features use TFC fluids, while trees are generated as TFC species, making the environment feel alive and consistent.

How to Install LostCities-TFC for Minecraft

Getting LostCities-TFC up and running requires a few careful steps, especially since it is designed for a specific modpack environment. The mod is built for Minecraft 1.12.2 and runs on the Forge mod loader. You will also need the base TerraFirmaCraft mod installed, as LostCities-TFC depends on its blocks and world generation mechanics.

To download LostCities-TFC, head to the official Technodefirmacraft modpack repository or the mod’s distribution page. Because this is an alpha release, it is not yet available on large public mod platforms. Once you have the .jar file, place it into your Minecraft mods folder alongside TerraFirmaCraft and any other required dependencies. Make sure your Forge profile is set to 1.12.2 before launching.

If you want a hassle-free setup, the foxygame.net launcher includes LostCities-TFC in its add-on catalog, letting you install the mod with a single click while automatically resolving Forge version compatibility and dependency checks. This is especially handy for players who want to jump straight into the ruined dimension without manually tracking down every required file.

After installation, you will need to configure the dimension ID in the mod’s config file if you want to avoid conflicts with other dimension-adding mods. By default, the Lost Cities dimension is set to 111, and you can access it through a custom portal or command. Remember, do not attempt to set the overworld to Lost Cities generation — the mod is not yet compatible with TFC overworld terrain, and doing so may cause world corruption.

Exploring the TFC-Infused Ruins

Once you step into the Lost Cities dimension, you will immediately notice the difference. Instead of vanilla stone bricks, the crumbling skyscrapers are built from TFC raw stone, cobblestone, and smooth stone variants. The highways stretch across the landscape, supported by pillars of andesite, granite, or basalt, depending on the local geology. Abandoned subway stations are carved from TFC bricks, and the tunnels are lit by flickering lanterns that cast eerie shadows on the walls.

The integration goes deeper than aesthetics. Chests and loot tables are populated with TFC items — metal ingots, ceramic vessels, and tools that fit the modpack’s progression. Dungeon spawners may release TFC mobs, adding a layer of danger that vanilla Lost Cities never had. The world feels like a genuine extension of TerraFirmaCraft, not a separate minigame.

Because the mod is still in alpha, you might encounter missing textures, odd block placements, or structures that generate partially. The developer is actively working on improvements, and feedback is welcome on the Technodefirmacraft Discord. However, it is crucial not to report issues to the original LostCities tracker, as these are modifications specific to this fork.

Compatibility and Current Limitations

LostCities-TFC is explicitly built for the Technodefirmacraft modpack and may not function correctly in other TFC-based packs without adjustments. It is not compatible with newer Minecraft versions like 1.16 or 1.18, as it relies on the 1.12.2 codebase of both LostCities and TerraFirmaCraft. The mod currently only supports city generation in a separate dimension; overworld generation is not implemented and could cause severe issues if forced.

Players should also be aware that this is an alpha release. Unexpected crashes, world corruption, or missing features are possible. Always back up your worlds before adding the mod, and consider testing in a separate instance. The developer has clearly stated that the mod is a work in progress, so patience is key.

Why Download LostCities-TFC?

For fans of TerraFirmaCraft who crave exploration and dungeon crawling, LostCities-TFC fills a unique niche. It transforms the familiar Lost Cities experience into something that feels organic to TFC’s harsh, realistic survival. The ruined cities are not just decorative — they are integrated into the modpack’s resource and combat loops, offering a new way to gather rare materials and test your skills.

Whether you are a server owner looking to add a fresh dimension to your TFC world or a solo player seeking a new challenge, this mod delivers a carefully crafted blend of two beloved mods. Just remember to treat it as an alpha, report issues in the right place, and enjoy the haunting beauty of a TFC city lost to time.
