This is my first bigger project I share online. It contains a dungeon of 3 parts with lots of riddles and traps. Good luck =)
If you have 'Single Player Commands' -Mods installed use 'goto AztekDungeon' to teleport you to the dungeon. If you don't have SPC you can download it here : http://www.minecraftforum.net/topic/94310-125-single-player-commands-v322-official-download/
If you don't want to install SPC, you can find the dungeon at: x: 101.98 y:64.62 z:397.43
Please do NOT destroy bricks to shorten or cheat the way through the dungeon and please don't empty dispencers.
