Chunk Cycle

ChunkCycle

A survival challenge on one floating chunk that never stays the same.

You start on a single chunk in an otherwise empty world. Every few minutes the chunk renews: everything on it disappears and a fresh chunk of a new biome takes its place. Gather what you need, build quickly, and keep moving — because the next renewal is always coming.

Features

Renewable chunks

• Choose the ChunkCycle world type: the Overworld, Nether and End become empty worlds with renewable chunks.
• Every renewal (default 15 minutes) picks a new biome (with a configurable chance to repeat the same one). All renewable chunks of a realm share the biome and connect seamlessly.
• On renewal, mobs and items inside the chunk vanish. Players are lifted to the new surface so nobody suffocates.
• Animals native to the biome spawn on every new chunk, so there is always something to eat.
• A stone ring (4 blocks wide) surrounds the chunk at y=64, and fluids at the edges are sealed with glass that disappears at the next renewal.
• Nether portals you build survive renewals.
• The first chunk is always a forest with at least one tree.
• Nether: its own renewable chunk with Nether biomes. End: a single renewable chunk behind the obsidian platform, small islands for the crystal pillars, and a working Ender Dragon fight with its exit portal.

Expansion and contraction

• Expansion Chunk (enchanted coal ore): use it on an empty chunk next to a renewable chunk to make it renewable too.
• Contraction Chunk (enchanted deepslate coal ore): marks a renewable chunk to be destroyed at the next renewal. The original chunk can never be destroyed.

Merchants and the Exchange Coin

• After each renewal there is a chance a merchant appears (one per cycle, then it leaves at the next renewal):
  • Expansion Merchant — sells Expansion and Contraction Chunks.
  • War Merchant — sells War Banners.
• Everything is paid in Exchange Coins, a currency you can only earn inside invasions.

War Banners and invasions

• A War Banner summons a themed invasion on an empty 2×2 chunk area: a symbolic version of a structure appears, opens a stone path toward you, and sends 3, 5 or 7 waves of themed mobs (bosses in the last wave).
• Defeat the last wave and loot chests drop with the structure’s loot, plus Exchange Coins. Rewards scale with the banner level. After a few minutes the whole camp disappears.
• Invasions can also start randomly after a renewal. The first invasion is guaranteed after a few renewals, so you can always get your first coins.
• Themes: Village (zombies and corrupted iron golems, drops villager spawn eggs), Pillager Outpost, Woodland Mansion, Desert Temple, Jungle Temple, Stronghold (drops End Portal Frames), Abandoned Mineshaft, Witch Hut, Igloo.
