Physics based mass destruction

I tested mass physics in UE4 and set up a little hoover vehicle that can shoot bullets to bring down a wall of 1600 stacked cubes.

It was a test, but one could think of scripting buildings from the cubes, or any other levels, and try to rescue the ragdoll that is sitting on the wall. Just adding a grab arm to the hoover vehicle.

All this has been tested with the idea of physics based gaming behind it. Everything in the demo is physics based. No scripting/animation at all.
