Kinetic Bombardment Rods are basically tungsten rods dropping at an great height.
This scene has designed just like one which is these rods are made of Tungsten.
Tungsten has a incredible high density at 193 kg/m^2 and can reach mach 20 speed in
real life.That makes it 20 times faster than the speed of sound.In the scene I made a bunch
of destroyable blocks at left.Just wait the rod and see its power.

Also these rods are designed to dropped from space so I might consider making a rod launcher
too!
