i only worked in two of the biomes and im not really sure how many of em there are. nut you can bet youll have at least a little fun getting between the two i did work in. youll also need the dynamic elevators mod just to get into bed! and if ya want i have a helicopter somewhere if ya get the thx helicopter mod. and interesting fact: it was war of the mobs in the main biome. they were fighting each other and then i came in with lightning and explosive arrows to keep them kids off ma lawn. it was an epic sight.
