The Lost Cities — Minecraft Mod

📖 Introduction

The Lost Cities is a world generation mod developed by McJty since 2017. McJty is a veteran modder behind popular mods like RFTools, Deep Resonance, and XNet, and Lost Cities is his most concept-driven and visually striking work. It's been ported steadily from 1.10.2 through 1.21.1, with code open-sourced under MIT on GitHub.

Open a world and collapsed skyscrapers, cracked roads, and abandoned vehicles run to the horizon. Every building is packed with chests, traps, and zombies, so there's effectively no end of places to raid, and you can dig down into layered subways, sewers, and basements. City profiles like 'Default,' 'Nightmare,' 'Atlantis,' and 'Wasteland' swap the whole mood and difficulty, and you choose whether to overwrite the regular overworld with cities or keep them as a separate dimension.

**What sets it apart** from other structure mods is that the city **isn't part of the world — it is the world**. Not one or two dungeons, but every visible horizon is city, which flips the gameplay loop from 'build a base and mine resources' to 'which building do I raid today?' The MIT license plus a deep config system lets pack authors freely reconfigure city density, building types, and loot tables.

In zombie-apocalypse packs like DeceasedCraft and Cursed Walking, it basically is the world. Ruined buildings simultaneously serve as loot caches, danger zones, and potential base sites — pair it with a gun mod like MrCrayfish's and the experience drifts toward something cinematic, clearing rooftops floor by floor. **Warning**: forget to pick the world type and you'll generate a normal world, so 'World Type' = 'Lost Cities' at world creation is the single most important setting.

🕒 When to Use This Mod

Set it up at world creation if you want a 'civilization fell' campaign — it shapes terrain generation itself, so adding it mid-save is awkward at best. The right moment is when you're explicitly planning a looting-focused or zombie-apocalypse playthrough, before you place a single block. After that, exploration becomes the actual gameplay loop.

📦 Where It Matters Most

In zombie-apocalypse packs like DeceasedCraft and Cursed Walking it basically is the world. Ruined buildings simultaneously serve as loot caches, danger zones, and potential base sites, and once you pair it with a gun mod like MrCrayfish's the experience drifts toward something cinematic — clearing a high-rise floor by floor instead of mining a hole and calling it home.

🎮 How It Changes Your Playthrough

Minecraft stops being a game about building a base and becomes a game about deciding which building to raid today. Standing on a collapsed rooftop, scoping out the next looting route through the skyline, feels like a different genre entirely — and after a few sessions, going back to mining holes for resources just feels boring by comparison.

🚀 Getting Started — First 30 Minutes

Lost Cities is a mod where one click at world creation decides your entire run. Get 'World Type' wrong and you'll be restarting an hour in — follow this flow exactly.

Step 1 — Pick 'Lost Cities' world type (5 min)

The single most important step in the create-world menu.

Create New World → More World Options
Change World Type to 'Lost Cities' (default is 'Default')
Pick a City Profile:

- Default: standard ruined city, balanced difficulty - Nightmare: higher zombie and trap density - Atlantis: drowned cities, underwater exploration focus - Wasteland: scattered ruins on barren terrain

If your modpack recommends a specific profile (e.g., DeceasedCraft), use that one

Skip this step and you generate a normal overworld — Lost Cities effectively does nothing.

Step 2 — Scout for a first base (15 min)

For the first 30 seconds to 1 minute after spawning, look around. Lost Cities spawns are random, so your starting environment varies wildly with luck.

Skyscraper rooftop: best sightlines + zombie access limited (top pick)
Basement / underground parking: only one entry to block, but watch for oxygen if flooded
Alley between buildings: fast movement, but exposed to zombie packs

Goal for step 2: one temporary base + one bed placed before nightfall.

Step 3 — First looting round (15 min)

Start with nearby 1–2 story buildings:

Chests: nearly every room has 1–2 — food, tools, resources
Watch for traps: dispensers (arrows), pressure plates (explosions), pit drops — scan surrounding blocks before entering
Zombies: vanilla + modpack variants. In multiplayer, split looter/escort roles
Rope / ladders: mandatory for highrise entry — falls are usually fatal, always carry some

Where to go next

5+ story buildings — diamond and iron loot rates climb sharply
Subway / sewer exploration — rare chests + extra zombie variants
Modpack-specific buildings: military sites in DeceasedCraft, hospitals in Cursed Walking, etc.
Migrate your base first floor → rooftop as you secure more height

💡 Gameplay Tips

Each building has chests with various loot. Search thoroughly.
Skyscrapers are dangerous but often have great rewards.
Don't forget about underground tunnels and basements.
Lost Cities only kicks in if you actually pick its world type at world creation — leave 'World Type' on default and you'll generate a normal world where the mod effectively doesn't exist. This is by far the most common first-time mistake; people often realize an hour in that they've been playing vanilla terrain wondering where the cities are.

⚠️ Common Confusing Points

• Some modpack configurations replace the entire Overworld with a city, while others add it as a separate dimension.

❓ FAQ

I made a world but I don't see any cities.

You didn't switch **World Type** to 'Lost Cities' at creation. It's the single most common mistake, and unfortunately the fix is **starting a new world** — there's no way to retroactively add cities to an existing save. (There's a dangerous chunk-regeneration workaround, but I wouldn't recommend it.) Next time, definitely change World Type in 'More World Options' before clicking create.

Which City Profile should I pick?

If it's your first time, **'Default'** is the safest pick — balanced zombie density, loot, and city size, good for learning. Once you're used to it, try **'Nightmare'** for harder difficulty or **'Atlantis'** for an entirely different environment. If your modpack recommends a specific profile (like DeceasedCraft's custom one), stick with that — it matches the pack's intended design.

Can skyscrapers collapse on me when I mine them?

Lost Cities itself has no physics simulation, so buildings don't collapse naturally. But **if you have Falling Tree, Block Physics, or similar mods installed**, removing support blocks can drop the upper floors. Be careful with that. Some modpacks like DeceasedCraft deliberately enable physics effects.

Traps inside buildings keep going off.

Pressure plates (explosions) and dispensers (arrows) are the usual culprits. **Building the habit of scanning surrounding blocks before entering a room** is the best defense. When entering a new room, walk around pressure plates or pre-destroy them with a pickaxe. Some modpack configs let you avoid certain pressure plates by **sneaking (shift) while moving**.

Can I run Lost Cities alongside other dimension mods?

Yes. Lost Cities can be configured as either the Overworld or a separate dimension, so it doesn't clash with mods like The Aether or Twilight Forest. Note though: if you replace the Overworld with cities, you lose normal biomes (forest, mountain, ocean), so you'll have to rely on other dimensions (Nether, End) for raw resource gathering.
