Done quite a while ago i've detailed the walkways with card tiles and some sand in the crevices, undercoated black then worked up the greys. I was looking for a very generic look and there are no modern touches apart from the loopholes in the corner section.
The ends are cleverly designed to push together (but not lock) to give a more solid wall effect or they could be scattered around as each piece can stand alone. The straights have two levels and the corner has four with the landing at the rear. There are two more kits which i don't have which are the gateway and a breached wall section.
