Mechanicum Ruins I did ages ago.
The bulkheads have been painted in the same style as the Manufactorium Ruins by simply undercoating black then heavy drybrushing Macharius Orange followed by Boltgun Metal. This way you can get great looking terrain painted rapidly and join the fight against plain grey plastic scenery!! Bases are optional, mine make the pieces sturdy and can rulewise delineate the 'moves through cover' etc. It is cut from a sheet of 3mm hardwood (fibreboard) and sanded at the edges to give a smooth curve.
For more Terrain ideas and to join in the fight against plain grey plastic scenery, see the TERRAIN posts. Thanks for reading.
