This is a beautiful set. I never knew it existed. Honestly, when I found it and did some research, it almost seems that it was only sold in the UK. I purchased it via Amazon from a UK seller. This set is amazing. It comes with several figures and the fortress details are outstanding.
It would have been awesome to see Mega Construx produce single figure packs like they did for Call of Duty, Monster High, and HALO. The characters could have been unlimited.
