With the 2nd Edition, came a new system of cardboard terrain clipped together with modular plastic bulkheads.

Only simple cardboard building sections were included with the original boxed game, but shortly after, a range of the modular terrain was released. With the advent of Necromunda and Gorkamorka, the same system was used, with specific terrain being released for those games.

Some of these terrain sets would continue into the 3rd Edition, with a re-re-branded industrial terrain boxset to co-incide with the updated book-only Necromunda (2nd Edition).
