This plugin was created by EPO (the creator of *Imperium Eternal*) for his old *Empire Earth* mod.
This weapon was designed with a much larger destructive range, but since it frequently caused the game to crash, I configured it to destroy buildings while dealing only minor damage to units.
I later added a RADIATION effect that the projectile releases upon impact, temporarily damaging all objects within a wide radius.
