This is a great addon set to Barricades. Along with Platforms and the Gate you now have an even greater flexibillity as to how you would like to construct your SciFi fort complex. I give 5 stars as this is another inexpensive addition that you can make as many as you would like. I recomend downloading the guide to also assist you in your decision. I decided that his was definately going to be added to my set!
