PLEASE view this world with the included mod TERATOMIC MOD 1.5.1.zip installed. You will need to have MODLOADER installed as well - it's available here: http://www.minecraftforum.net/topic/75440-v151-risugamis-mods-updated/
I've also included the texture pack for 1.5.1 alone. You'll miss out on custom blocks and items, and some builds may appear incomplete, but at least most of the world will look right.
When the map is released as an adventure map in its final format, the experience will be extremely limited without using the mod. If you are downloading this map because of a particular build I've included, please understand that it may contain custom blocks and items which depend on the Teratomic Mod to be complete.
See the included README file for more info/instructions.
