I've been looking forward to this vehicle for a while, and am quite impressed with it. It was definetley larger than I had first thought it would be.
There is some assembly required. The eyes, guns, and side tread pieces need to be attached.
This vehicle has two forward firing missiles, and two opening hatches for a driver and gunner. The two side tread pieces have wheels on the bottom, and the large center tread is made of rubber and can move. The two inside parts have little detail, but the outside has some nice detail and a good looking paint job. The tops of the side tread pieces do not have foot pegs on them, which was disappoiting since we saw the droids standing there in the movie.
The two hatches can only be opened from one side.
