My original hijacked map used vanilla minecraft, but this one uses the latest Direwolf 20 pack from the feed the beast launcher.
I included some Multiplayer features that wasn't in the vanilla as redpower micro-blocks isn't added into vanilla minecraft, area's that include this feature is the middle of the map. Other features are better aesthetics from FTB only blocks. Leave a comment and visit my official minecodproject website (here) which includes more maps like this one.
