Description

Notes for OpenLOCK Barbican:

Rampage is a modular interconnecting scenery-building system that allows you to build everything from perfect dungeon tiles to large buildings and fortifications.
Rampage uses ‘OpenLOCK’ locking clips to attach the walls to floors so you can mix and match to make amazing combinations. The walls tessellate perfectly, allowing you to make true-form tiles, rooms, and buildings.
Please also get the locking clips from the base pack here.

what scale should i print these at for 30 mm miniatures?
