Part of a series of 18 models of a brick constructed tunnel complex. Tunnels come in both square and round profile and both profiles may be linked together. This is an indoor model so outer textured are there just to assist placing. May be used to make tunnel complexes from small to many 'miles' long. Could be great for multi-player maps. Tunnels may be populated by debris, enemies ETC. Works in a mix 'n' match fashion with my other tunnel packs.
