Questions about McMeddons Advent Map 21

What is McMeddons Advent Map 21?

McMeddons Advent Map 21 is a hand-made survival world of 2,048 × 2,048 blocks, made with WorldPainter, World Machine, Gaea, Axiom and WorldEdit, built for Minecraft Java 1.20.2. You download the world folder and play it like any other save, in singleplayer or on your own server.

How big is McMeddons Advent Map 21?

2,048 × 2,048 blocks, so about 4 million blocks of surface. Walking from one edge to the other takes roughly 8 minutes at normal walking speed. The terrain runs from Y -64 to Y 320.

Outside that area the world keeps generating normal vanilla Minecraft chunks, so you never hit a wall, you just leave the built part behind.

Which Minecraft version does McMeddons Advent Map 21 need?

McMeddons Advent Map 21 is made for Minecraft Java 1.20.2 and opens in 1.20 and later. Between the two, anything added after the release you load it in is removed or replaced (new biomes load as plains), so 1.20.2 or newer shows the world as built. Releases older than 1.20 cannot open it.

Bedrock players need a converted copy. See the Bedrock notes in the FAQ.

Which biomes are in McMeddons Advent Map 21?

19 in total. The land is mostly Plains (43.2%), Beach (22.2%), Jagged Peaks (9.4%) and Meadow (7.5%), counted as shares of the land rather than of the whole map.

Water covers 47.0% of the map, and land 52.8%.

The full breakdown is further up this page, with every biome and its share.

Which structures are in McMeddons Advent Map 21?

7 of the 20 structure types the scan checks are confirmed present: surface (1/8), underground (2/6), ocean (2/4), portal structures (1/1) and settlements (1/1).

Not confirmed: Abandoned camps (missing), Desert pyramids (missing), Igloos (missing), Jungle pyramids (missing), Pillager outposts (not checked) and Swamp huts (missing). "Missing" means the scan looked and it is not in the built map; "loot only" means its chests are here but the structure is not; "possible" means only indirect evidence was found.

The structure list above names every one of them.

Is McMeddons Advent Map 21 ready to play in survival?

Yes. A scan of the world file confirms loot tables, structures, animals and ores, so the survival loop runs from the first night: chests hold the game's real loot tables, mobs spawn as they do anywhere else, and you can mine, farm and build without adding anything. It plays in vanilla Minecraft, with no mods, no datapacks and no creative mode.

The world contents report at the bottom of this page holds the item-by-item detail.

Can I look at McMeddons Advent Map 21 before downloading it?

Yes. Open it in the 3D explorer and fly the real terrain in your browser, with the biomes, the caves and the marked structures. Nothing to install.

How do I install McMeddons Advent Map 21 on Java Edition?

  1. Unpack the archive you downloaded.
  2. Open your saves folder. On Windows press Win + R and enter %appdata%\.minecraft\saves. On macOS it is ~/Library/Application Support/minecraft/saves, on Linux ~/.minecraft/saves.
  3. Move the unpacked folder in. It must be the folder that contains level.dat, not a folder wrapping it.
  4. Restart Minecraft on 1.20.2 or newer and pick the world in singleplayer.

Full install guide

Can I play it on Bedrock, or on a server?

Bedrock needs a converted .mcworld copy, and converted worlds carry their own quirks around spawn, chests and villagers.

For a server, drop the world folder in as the server's world and start it.
