This is my version of the CIS Spider Walker from "Star Wars Battlefront 2". It has 1 Security Droid. It has two lasers, top and botom, and includes "Real" walking feet.
I must say, much better than the set. My only complaint is the security droid "pilot". (The honig spider droids were indipendent units, the same as a regular battle droid, but of a more artillery category.)
Aside from colors, great. But the actual spider-droid appeared in episode two, and all droid vehicles (other than the ATT, MTT, and STAP) are actually droids themselves.
