Everything up to now was purely based on blocks, which were individual units. The only way they affected each other was with collisions. Thanks to Unity5, which has better and faster physics, connecting blocks near eachother is now possible.

Walls along with pillars, which are connected to neighbouring now make up bridges, roofs or anything that’s above the ground with the help of supports.

When dropping explosives near the structure, joints that don’t reach their breaking points allow some parts of the building to stay almost intact. The left wall along with some glass stayed together.
