This set will get you started with our Sector 73 line, providing you a solid base to work from at a discounted price.
Included in this bundle are: 1x SC73-001 (small square building), 1x SC73-002 (rectangular building), 1x SC73-003 (L shaped building), 1x SC73-004obj (large objective building), 1x SC73-01x (set of 3 alternate roof sections), 1x SC73-059 (Set of 3 short and 2 long ladders), 1/2x SC73-052 (1x U shaped stairs), 1/2x SC73-053 (1x short walkway and 1x long walkway).
You can then expand easily by adding additional buildings (or extra floors for buildings since you will have roof sections to spare), scatter terrain, and billboards.
NOTE: The main image shows all items included laid out separately other than the proper number of ladders (includes 3 short and 2 long). The other images show some simple ways that the buildings could be arranged.
