This is my new map for the Invasion mod (found here: minecraft-mods.org/invasion-mod/ ) that is somewhat small. I recommend sleeping in the beds in the bunker in the back of the castle. There is an optional bonus for you to use if you install the Utility mobs mod. (found here: www.minecraftforum.net/topic/1153874-147-smp-forge-father-toasts-mods-special-mobs-and-lava-monsters/ ) The blocks are assembled the way they should be placed in the real world, but they are inside the chest that contains all of the invasion items. Stock up on supplies before you start, and have fun! Make sure you are in survival mode. The obsidian turret needs a netherbrick fence, so delete the extra fence and spawn yourself one. The item id is 113. You would use /give (your name) 113 1
