Extract the Criswelvania vRC2 folder to your .minecraft/saves directory. Do NOT create a new folder when extracting, the World folder is contained nin the archive file.<br />

Criswelvania is current with Minecraft version RC2. No mods are required to play. An AdventureCraft-modified version may be forthcoming in the future, but the intention is to maintain a vanilla MC-compatible version as the official edition.
