This is a simple proof of concept to show destructible objects in Unity3d similar to how it's done in the frostbite engine. Could be textured a little better, and particles could be better, but shows a great proof of concept on the idea.
This is just a wall explosion, and not the whole building collapsing in on itself, but that rarely happens in the frostbite engine. I'm thinking of a way to make a dynamic collapsing in on itself system, but it may only be possible with a pre-made animation while inside of unity.
