From the campaign:
Infinite Crypt is a new class of laser-cut gaming terrain that we haven’t seen before. It provides modular architectural elements that are solid and sculptural, and can be reconfigured to create all sorts of adventurous locations – catacombs, labyrinths, fortifications, bridges and more.
Rather than whole buildings, Infinite Crypt standardises towards 2? x 2? x 1? elements with which you can build whatever you like. We’re looking to keep the cost right down – because however cool and configurable it is, you need to make sure you can get your hands on LOADS of it.
