This is the Vertical Bundle Kickstarter set (Archon Studio, 2022) from the Rampart: Modular Terrain line. It cnsists of two packs of unassembled, unpainted plastic elements to add vertical accessibility to a terrain build. Part 1 includes functional floors (88 elements) and Part 2 includes bridges, ladders, ramps, and stairs (54 elements).

Both packs are new in shrink wrap, but the boxes have some crushing.
