Advent Map 16 is a hand-made survival world of 3,072 × 3,072 blocks, made with WorldPainter, World Machine, Gaea, Axiom and WorldEdit, built for Minecraft Java 1.21.5. You download the world folder and play it like any other save, in singleplayer or on your own server. ### How big is Advent Map 16? 3,072 × 3,072 blocks, so about 9 million blocks of surface. Walking from one edge to the other takes roughly 12 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 Advent Map 16 need? Advent Map 16 is built for Minecraft Java **1.21.5**. Newer releases normally open it fine. Opening it in an *older* release is not supported: blocks and structures added after that version cannot load, and the world can be damaged by the attempt. Bedrock players need a converted copy. See [the Bedrock notes in the FAQ](https://mcmeddon.com/faq#install-bedrock). ### Which biomes are in Advent Map 16? 29 in total. The land is mostly Plains (35.9%), Beach (10.8%), Dark Forest (8.2%) and Stony Shore (6.8%), counted as shares of the land rather than of the whole map. Water covers 36.7% of the map, and land 62.7%. By volume this world's caves are Normal Caves (94.1%), Lush Caves (3.0%) and Magma Caves (1.6%). The [cave breakdown](https://mcmeddon.com/worlds/20251216-advent-map-16#caves) has the rest. The [full breakdown](https://mcmeddon.com/worlds/20251216-advent-map-16#biome-composition) is further up this page, with every biome and its share. ### Which structures are in Advent Map 16? 5 of the 19 structure types the scan checks are confirmed present: surface (1/7), underground (2/6), ocean (1/4), portal structures (1/1) and settlements (0/1). Not confirmed: Desert pyramids (not checked), Igloos (not checked), Jungle pyramids (not checked), Pillager outposts (not checked), Swamp huts (not checked) and Woodland mansions (not checked). "Searched, not found" means the scan looked and came up empty; "not checked" means it has not been looked for yet. [The structure list](https://mcmeddon.com/worlds/20251216-advent-map-16#structure-coverage) above names every one of them. ### Is Advent Map 16 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.
