Hi everyone!
Here's a short description of this map. To see the full description (including the achievement list), go to the original post on minecraftforum: http://www.minecraftforum.net/topic/1919223-giant-minecraft-survival-map
So, have you ever sat down and wondered "Huh, I wonder what it would be like to be 2 pixels tall in Minecraft?" Well, your wondering days are over. Giant Minecraft Survival is an island made out of 16x16x16 blocks. However, they are not just boring, solid blocks. They are filled with fun and interesting things (like mini biomes).
Basically the achievements for the map range from finding emeralds in the mini extreme hills biome to exploring the Nether (also made of giant blocks), and killing the Ender Dragon (in a giant block End).
Now I made this map a few months ago, in 1.6, so some things aren't completely up to date (like the only flowers are dandelions and what were roses but are now poppies), but that won't affect too much.
Note: You'll have to turn off the clouds in your video settings because the map is much higher than usual, and the clouds are at sea level.
