This collection was total ownage. With 4 different creative sets combined, you could build like anything. The 4 main mechs were able to be made at the same time, and also had an instruction booklet full of many great ideas. I made this amazing dude one time and its was pretty cool yeah =]. Huge variety of elements, including all the primary colors, oranges, greens, blacks, and silver. Basically almost anything you would use to make a robot thing.
