This set allows you to create the ultimate battleground for the Nano V2. The V2 bugs will climb through the black tubes to either side of the elevated arena, scurrying over the orange bridge, through one-way gates, to meet in the center battle platform. Includes a bridge battle platform exclusive to this set. Builders have even more control over how to construct the set, and can customize the flow of traffic by filling the attachment points on the HEX cell base with accessories such as fixed pegs and rotating flags that help direct where the explorative micro robot roams. Compatible with all other V2 sets.
