Asteroid 5251 is a Minecraft adventure map.
You are an astronaut whose rocketship crash-lands on a barren asteroid in the middle of space-nowhere. Some exploration reveals that the asteroid is far from empty — it's full of the ruins of a civilization of people who mysteriously died out after some cataclysm. This one is notable for being an adventure map that's heavy on plot.
This map contains examples of:
- Abandoned Laboratory: Alpha Hub has one where they were doing experiments on Nether materials.
- Apocalyptic Log: The story is told entirely through these, usually in the form of letters and diary entries.
- Artifact of Doom: The crystal in the Nether fortress (actually a diamond block) that is what's powering the Zombie Apocalypse.
- Beneath the Earth: Gladsbury's citizens lived beneath the earth under an artificial sun for thousands of years.
- Colony Drop: It turns out that this is what happened to the planet Leeir — it got blown apart by a meteor shower, turning it into the very asteroid you've crash-landed on.
- Decade Dissonance: Intentional: The medieval Gladsbury folks and the futuristic Leeir people lived smack next to each other for quite a long time before they discovered one another.
- Deus ex Machina: In the end, you are rescued and handed a spaceship free of charge by a race of aliens called the Durinians.
- Evil Tower of Ominousness: The fortress in the Nether has a couple of these, all topped with Spikes of Villainy.
- Flying Saucer: The Durinian ships are huge flying saucers.
- Fungus Humongous: One area contains a bunch of giant mushrooms made out of glowstone. The biggest one even has a little house inside.
- Lethal Lava Land: You can take a roller-coaster-esque minecart ride through one.
- The Maze: There's a really elaborate one under Lord Muford's castle.
- Minecart Madness: There's one through a Lethal Lava Land, though fortunately, there are very few obstacles, so you can mostly just enjoy the ride.
- Pipe Maze: One of the puzzles in Alpha Hub is a pipe maze.
- Ragnarök Proofing: All of the minecart lines still work just fine, although several are dead ends due to cave-ins.
- Raygun Gothic: The futuristic civilization of Leeir has this look, being mostly constructed out of shiny iron, glass, and glowstone.
- Terraform: At the beginning, you're given a "Bio-Terrain Kit" that includes grass, saplings, flowers, wheat seeds, cacti, and sugar cane, allowing you to terraform the crater you crash-landed into, which then prompts cows, pigs, wolves, etc to spawn in.
- Underground Level: Most of the levels are underground.
- Weird Sun: Gladsbury used to have an artificial sun.
