It occurred to me that epic gamers seem to make very small terrain. So i deced to make some big terrain, while its not practical to make 2 meter tall sections of hive innards, 50-80cm tall looks like a good hieght. To achieve this swiftly and at the minimum expense i propose the use of square flowerpots. You can get 100 for a few £ and even with the larger ones counted in i think a 70cm tower will cost less than £2. Poly-cement sticks to them so they will be easy to detail.
I need to go out and buy a lot more pots, but a brief play about with a few looked like this, so i think the concept will work:
Hopefully ill make enough to cover a table, with a lot of gantry and walkways to cut the LOS corridors. A large fly-over motorway 20cm or so off the ground on arched supports would be cool as well.
It was inspired by the pictures in the E:40k battles booklet, which has lots of small pictures of battles set against vast, vast cities.
